Stanford University scientists say experiments on ancient Chinese stone tools, including 15,000-year-old hand axes, have solved a longstanding mystery about the critical technological transition from rudimentary hand tools to more versatile ground-edged tools, suggesting these new technologies enabled uses beyond food harvesting.

The research team behind the new analysis said the discovery of ground-edged sickles and knives in Neolithic North China, likely used for fiber production and harvesting, combined with their replica-based experiments, highlights the growing technological capabilities of the transition between Paleolithic and Neolithic peoples.

“The combined experimental and archaeological evidence from the site of Peiligang indicates that the emergence of ground-edged tools marked a significant step in technological specialization from the Late Pleistocene to the Early Holocene,” the researchers write in a paper detailing the work.

Mysterious Technological Transition Hidden in 15,000-Year-Old Stone Tools

According to lead author Ran Chen and colleagues, archaeologists widely regard ground-edged cutting tools like the modern sickle as “technological hallmarks of early agriculture in North China.” However, they note, the functional foundations of this advanced toolmaking capability “remain insuf­ficiently tested.”

The research team also noted that most analyses of the transition from the Upper Paleolithic to the Early Neolithic (ca. 15,000–8,000 BP) in ancient China have viewed tools through “the lens of food production.”

“Within this framework, cutting tools, including early flakes and blades and later ground-edged sickles and knives, are often interpreted primarily as implements for harvesting cereals through cutting stems and leaves,” they explained.

The researchers said these earlier findings made them wonder whether this “food-focused perspective” could have led researchers to miss the broader range of plant resource exploitation possibilities in some of the 15,000-year-old stone tools previously discovered, prompting their replica-based experiments.

“The development of stone tool technology in North China provides a framework for reassessing this long-term relationship between plant use and technological change,” they explained.

Experiments Reveal Ground-Edged Tools Were Multifunctional Implements

To test their hypothesis, Chen and colleagues analyzed 140 stone artifacts previously collected from the Peiligang site in Henan Province, China. This included some 15,000-year-old Upper Paleolithic flaked stone tools and several more advanced Early Neolithic flaked and ground-edged stone tools.

Rather than test irreplaceable artifacts, the study authors created realistic experimental replicas.

Testing the effectiveness of the oldest, most rudimentary stone flake designs and the more technologically advanced ground-edged tools for harvesting seed-bearing grasses, the researchers found little measurable advantage between the two designs.

However, when the researchers compared the 15,000-year-old stone flake tools against ground-edged tools made thousands of years later, they found the more technologically advanced tools were “significantly more efficient at cutting thick-stemmed weeds and fiber-yielding plants.”

“Upper Paleolithic flaked tools were multifunctional implements used for processing diverse plant and animal materials, and Early Neolithic flakes continued to serve similarly flexible roles,” the study authors explain. “In contrast, Early Neolithic ground- edged tools show marked specialization in plant- related tasks.”

More Advanced Tools Emerged Through Broader Functional Demands

When discussing the experimental results, the team noted that their findings were supported by microfiber and starch residues found on some of the ancient tools, suggesting that “ground- edged sickles and knives were used not only for plant foods but also for harvesting and processing fibrous plants.”

“These findings indicate that ground- edged cutting tools emerged through broader functional demands, including fiber production, and potentially vegetation clearance, rather than cereal harvesting alone,” they explained.

Beyond the food-harvesting uses of ground-edged tools, Chen and colleagues said their identification of non-food plant labor like fiber production as an important driver of technological evolution and specialization “reframes the emergence of ground- edged tools as part of a broader technological and economic reorganization in early Holocene East Asia.”

“These findings identify nonfood plant work as an important contributor to the adoption of ground-edged cutting tools and show that tools conventionally linked to early agriculture were shaped by broader demands than food production alone,” they explained.

Finally, the study authors suggested that their analysis of 15,000-year-old Chinese stone tools could “invite renewed attention” to ancient fiber-based economies and nonfood plant use during forager–farmer transitions and in early farming societies beyond China.

The study “Plant fiber exploitation contributed to the emergence of ground-edged cutting tools in North China” was published in Proceedings of the National Academy of Sciences.

Harvard-Smithsonian Center for Astrophysics scientists studying water ice believed to be stored in the Moon’s ‘pits of eternal darkness’ have concluded that there likely isn’t enough of this critical resource to support long-term future human colonies, meaning visions of large-scale cities on Earth’s largest natural satellite may be more science fiction than science fact.

Conversely, the researchers calculated that smaller settlements with fewer than 10,000 human colonists could have enough accessible water to survive for centuries. They also suggested that other technological advances in water harvesting or advances in scanning techniques that explore below the top few meters of surface regolith may reveal significant amounts of hidden lunar water.

Water Ice Stored in Moon’s Pits of Eternal Darkness

The Moon’s surface is covered with visible evidence of asteroid collisions. Along with its textured appearance, some of these massive impact craters contain areas that are permanently shaded from direct sunlight.

The Harvard-Smithsonian research team behind the new study said some of the earliest “pits of eternal darkness” could be over one million years old. More critically, they can maintain a temperature of 110K, or just above absolute zero. At this low temperature, frozen water ice trapped in the sunless craters won’t lose more than a millimeter of thickness to space every billion years.

When announcing the new study, the researchers noted that “a succession of Moon-orbiting missions” has mapped out possible locations of stored water ice since 2013. The results suggested that the Moon’s pits of eternal darkness may contain as much as a billion tons, with the largest concentrated around the Moon’s northern and southern poles.

Since those missions, scientists and industrialists have begun to speculate about the viability of long-term human lunar habitation. Unlike astronauts trapped in capsules or space stations, lunar colonists could theoretically possess enough on-site water to support farming, full-service bathroom facilities, and production of hydrogen-based fuels.

Still, researchers wondered if one billion tons of stored water ice is enough to support the types of cities that billionaire industrialists and science fiction authors have proposed.

On-Site Solar Power Could Support One-Million-Person Lunar City

To start, the team modeled how long large human settlements ranging from 100,000 to one million people could survive on the water stored in lunar pits of eternal darkness. This included water-recycling rates up to 98%, as achieved on the International Space Station (ISS).

After running the numbers, the team found mixed results.

First, even colonies up to one million humans wouldn’t run out of power. The team said that number is based on solar power generation and excludes nuclear reactors.

Instead, the Harvard-Smithsonian team proposed constructing one-kilometer-tall solar energy towers near the rims of the craters. Their models suggest that an array of towers covered in photovoltaic arrays could generate three gigawatts of usable electricity.

The team noted that the materials needed to build solar panels, including the primary ingredient, silicon, are plentiful on the Moon, meaning future lunar colonists could manufacture new solar power-generating towers on-site. Such lunar colonists could theoretically maintain enormous AI data centers near these towers capable of servicing paying customers back on Earth.

“That would be the start of a true lunar economy,” the research team explained.

Even Generous Water Ice Estimates Limit Large Lunar Colonies

When the researchers crunched the water numbers, long-term lunar habitability became significantly more dubious. In fact, most estimates had future lunar colonists exhausting the most generous one-billion-ton projected supply of water ice within “a few years.”

When researchers modeled an ISS-level water recycling efficiency level using those same water estimates, a colony of one million humans would run out of water “in just over a century.”

“And today’s best estimates of the amount of water on the Moon are about 30 times less than a billion tons, shortening the time to water exhaustion by the same factor,” they add.

For example, if more conservative ‘pits of eternal darkness’ water ice estimates are closer to reality, the researchers said that “even a small city” likely wouldn’t make it past a decade before they had tapped the Moon dry.

Untapped Sources Could Improve Long-Term Habitation Prospects

Fortunately, the news was not all bad. When the team assumed a smaller “Moon village” of over one thousand people, up to a larger settlement of 10,000, the researchers found that the water ice stored in the Moon’s pits of eternal darkness “would instead be sustainable for several centuries or more.”

The team also suggested alternate solutions for supporting a larger, long-term lunar settlement. These included potential improvements in water recycling, improved farming efficiency, or mining nearby asteroids for water.

The team also noted that additional pockets of stored lunar water ice may be awaiting discovery, suggesting that finding such lunar water may be easier than achieving sufficient farming and recycling efficiency improvements.

“Current water surveying techniques do not reach below the surface more than a few meters, while the rubble-like rocks of the surface regolith typically extend tens of meters down and may contain water in the cold traps,” they explained.

The study “No Cities on the Moon: a Billion Tons of Water is not enough for Sustainability” was published in Frontiers in Space Technology.

Scientists investigating a 66-million-year-old mystery have revealed that a bird feather embedded in fossilized dinosaur excrement suggests that the ancestors of modern birds who survived the dinosaur-killing asteroid that also wiped out all other ancient bird species benefited from the waterproofing properties of their feathers.

The newly analyzed bird feather fossil that provided the missing clues comes from an extinct bird group called Hesperornithiforms and not from the ancestor of modern birds, Neornithes.

However, the team said subtle differences between the species suggest previous theories crediting adaptation to water diving as the key to Neornithes’ survival were likely on the right track.

Survival of Modern Bird Ancestors Posed a 66-Million-Year-Old Mystery

When a huge piece of space rock slammed into Earth, killing off virtually all dinosaur species save the ancestors of modern birds, the event also left behind a 66-million-year-old mystery. How did these ancient avians survive this apocalyptic event, resulting in every bird species we see today?

Jingmai O’Connor, the associate curator of fossil reptiles at the Field Museum in Chicago, said her career has been spent analyzing fossils to try to answer this single, critical question. However, unlike the new poop-encased bird feathers, most were not so ‘naturally’ protected from the ravages of time.

“It’s such a beautiful, well-preserved feather, from such an unexpected source, and it’s exciting that it could help us answer this huge question in paleontology,” explained the lead author of a study detailing the new analysis. “As far as I know, no one has ever thought to look for feathers or to study feathers in coprolites, so this project was really exciting.”

Dinosaur Dropping Provided Effective Preservation Medium

Researchers discovered the ancient bird feather in 2016 in Montana. Although she initially suspected it could be a coprolite rock (fossilized feces), O’Connor said she couldn’t confirm the theory for a decade.

The situation changed when O’Connor and Nate Carroll, a co-author of the paper and paleontologist at the Carter County Museum in Ekalaka, Montana, gained access to the micro-CT scanner at USC’s medical campus in Los Angeles, California. According to O’Connor, that’s when “the full feathery fabric of this fossil feces” started to finally reveal itself.

“Every hour processing the data revealed another feather, another scale, another bone—in stunning 3D,” Carrol also recalled.

Along with multiple feathers and tiny fish scales, the ancient dinosaur poop, which may have come from a Tyrannosaurus Rex, also contained legs from a hesperonithiform bird.

O’Connor said hesperonithiforms were ancient aquatic birds with similarities to modern loons. Critically, these cousins of the modern bird ancestor group had evolved specialized feet to hunt for fish by diving deep into the water.

“The feathers showed adaptations for being underwater that we see in living aquatic birds,” O’Connor explained.

Notably, the team said this evolution likely cost ancient hesperonithiforms like the one that was consumed by a dinosaur the ability to fly.

Connection to Modern Birds Offers a Solution 

Although the bird group represented by the fossilized feather did not survive the dinosaur-killing asteroid, its connection to the ancestor of modern birds appears to support a previously proposed theory that adaptation to water may have helped Neornithes survive. O’Connor said she thinks that small differences in the feathers of the two ancient bird species hold the answer to a 66-million-year-old mystery.

“We think the types of feathers that these birds had, and/or the way they molted those feathers, may have been one of the underlying causes of the selectivity of the end-Cretaceous mass extinction,” the researcher explained, adding that this is “essentially why some birds died out and why others survived.”

Specifically, O’Connor pointed to the “smaller, fuzzy, primitive body feathers” found on the extinct bird “that we associate with dinosaurs and enantiornithines” alongside more modern-looking waterproof adaptations.

The team said that these evolutionary relics suggest that hesperornithiforms like the one that left behind its feathers were an evolutionary bridge between older bird groups and the Neornithes that survived the cosmic collision. Even more critically, the team said these earlier feather structures may not have retained heat as effectively as Neornithes feathers, allowing one species to survive the asteroid and another to die in the extreme cold that followed.

“The hesperornithiforms retain primitive feather types that may not have been as efficient for insulation as modern plumaceous feathers, and that could explain why they went extinct along with the enantiornithines,” O’Connor explained.

The study “Bird feathers from a Late Cretaceous coprolite” was published in Current Biology.

Defense aviation company Hermeus has announced the development of Ramjet-X, its next-generation ramjet propulsion test vehicle capable of carrying test payloads to high Mach speeds.

The company said Ramjet-X, designed to launch mid-flight from a carrier aircraft, offers the key advantages of competitive high-Mach test platforms while keeping costs low enough for a wider range of mission profiles.

Pre-flight testing of Ramjet-X is already underway, with its first official prototype test flights expected in 2027.

Ramjet-X Will Launch Mid-Flight from Quarterhorse

Most conventional jet engines can’t achieve supersonic speeds without dumping raw fuel into an afterburner and literally rocketing past the sound barrier. To travel at high Mach speeds without relying on rocket-style propulsion, engineers have turned to ramjet engines.

While ramjets are effective, they rely on the high-speed influx of air to operate. This limitation means aircraft equipped with this type of propulsion must be propelled to higher speeds by another craft or booster rocket before they can engage.

In an email to The Debrief, a Hermeus spokesperson explained that current options often rely on “large and expensive” boosters that are discarded after each test. Conversely, Ramjet-X relies on the company’s reusable aircraft to reach launch velocity.

“Ramjet-X is designed to be carried by Quarterhorse, which provides the speed and altitude required for deployment,” the company told The Debrief.

The company could not disclose what speed Quarterhorse must achieve before it can launch Ramjet-X. However, the spokesperson did note that the launch craft is designed to return to home base for future missions.

When asked about Ramjet-X’s specific operating velocity once it disengages from Quarterhorse and engages its ramjet propulsion system, the company could only say the vehicle will operate at “High-Mach speeds.”

Conventional ramjets use a combination of high-velocity air and fuel to achieve extreme velocities. Hermeus said they cannot disclose specifics about Rocket-X’s fuel requirements.

Mission Profiles and Repeatable Architecture

Because of the sensitive nature of potential future missions, Hermeus was cautious about sharing specifics of any planned missions. The company also couldn’t provide technical details on what a typical mission profile might look like.

However, a Hermeus spokesperson told The Debrief, the vehicle’s architecture “allows customers and partners to integrate payloads, sensors, communications and computer systems, autonomy, material samples, propulsion technologies, and other experimental hardware and software onto Ramjet-X for testing in representative sustained high-Mach conditions.”

Hermeus also highlighted the potential cost savings of a “repeatable platform, launch architecture, and flight-test infrastructure,” designed to dramatically lower costs without sacrificing versatility or reliability.

“Instead of relying on a large dedicated expendable booster to accelerate the test vehicle into its ramjet operating regime, the launch aircraft provides much of that energy and then returns to fly again,” the company told The Debrief. “This architecture allows Hermeus to fly more by reducing the cost of expendable launch hardware.”

“High-speed flight testing is extremely expensive, and you don’t get many shots at it,” Hermeus CEO Zach Shore explained.

“Another Order of Magnitude Reduction”

Hermeus said specific unit costs are not currently available. However, they said a projected cost per minute of high-Mach test time “is in the low $100k’s per minute.” For comparison, the company highlighted the historic and current costs of high-Mach flight testing.

“Most of the below comparisons are rocket-based but will give you an idea how costly high-Mach tests are and why Ramjet-X will fundamentally change the equation,” Hermeus told The Debrief.

Older examples include NASA’s X-43, which achieved around 21 seconds of high-Mach flight, and the Air Force’s X-51, which achieved around 350 seconds. Hermeus said both multi-year efforts cost around $450 million each in today’s dollars.

Current options include rocket-powered test flights aboard Rocket Lab’s HASTE, which Hermeus said run $10-20 million each, “not including the expendable cruise or glide vehicles.” The company also pointed to Stratolaunch Talon-A missions.

“Even though fully reusable, (they) are $10-12m per flight for a few min of on-condition time,” the company told The Debrief.

Conversely, Hermeus said its current projections of less than a million per minute offer potential customers “another order of magnitude reduction in the problem that matters most.”

“Ramjet-X is being designed around simplified manufacturing, rapid production, and expendability in meaningful quantities rather than the traditional model of building a small number of highly bespoke high-speed test articles as was done in other high-speed airbreathing flight test programs like X-43 and X-51,” the company told The Debrief. 

Development of Ramjet-X is already well underway

When detailing the newly announced Ramjet-X’s benefits, Shore noted that their system gives them a way to place new systems into sustained high-Mach environments “without building an expensive one-off test program every time.”

“Bringing speed, sustained flight, and scalability all into one system lowers the barriers to gathering extremely valuable data from these conditions and accelerates programs for both us and our customers,” the Hermeus CEO explained.

When announcing Ramjet-X, Hermeus said the vehicle’s ramjet engine is already undergoing extensive testing at its Florida-based HEAT facility. Future tests will occur at the company’s California headquarters, with the first flight tests planned for 2027.

A University of Cambridge-led research team has announced the discovery of a 560-million-year-old animal fossil preserved in three dimensions (3D) in a sheep field in the Norwegian Arctic.

The exceptionally rare Ediacaran Period fossil is the first of its kind in Europe in decades and gives scientists a unique window into a period of Earth’s history when the first complex life forms began to appear.

The discovery suggests the site could hide an entire lost ancient ecosystem that has remained hidden for hundreds of millions of years.

3D Fossil of 560-Million-Year-Old Lifeform ‘Unlike Animal Life Today’

When announcing the historic discovery, the Cambridge-led team noted that the fossil, called a Charnia, resembles a fern more than any animal life we would likely recognize today.

For example, Charnia has none of the organs we typically associate with animals. The archaic life form also lacks a mouth or visible means of locomotion. The closest modern comparison would be a sedentary jellyfish.

While previous efforts have identified ancient animal-life fossils from this period, the team noted that most are found as “flat impressions.” As a result, Professor Neil Davies from Cambridge’s Department of Earth Sciences said that many fossils from this period “occur as impressions where they’ve been squashed down under layers of rock,” like a flower pressed into a book.

“As a fossil record, the Ediacaran has several things working against it, primarily that most organisms were soft-bodied and skeletons hadn’t evolved yet, so that they are harder to preserve,” the team member and co-author of the study detailing the research explained.

Dr Veema agreed, while noting the difficulty in finding such rare specimens.

“Fossils need to be embedded within sedimentary rocks to be found, so if the rocks themselves are less common, then that makes the fossils harder to find,” the researcher explained. “Most Ediacaran fossils come from just a handful of locations, which makes it exciting to find them somewhere new.”

Fortunately, the newly identified 560-million-year-old life form was preserved in all three dimensions. The team said that discovering an ancient life form preserved in 3D is incredibly rare, particularly for soft-bodied organisms like Charnia. Finding one from this extremely ancient time, when animal life first began to appear, is even more unlikely, making the discovery unusually rare.

Well-Preserved Charnia Reveals Previously Unknown Details

560 million years ago, when this Charnia was still alive, evidence suggests that it was buried during an ancient underwater avalanche. This sudden submergence also filled the animal’s body with sediment. The researchers said these events caused the fossil to become preserved in 3D

For example, the research team identified small ridges along the animal’s branches. Called keels, these extremely subtle features had never been detected in other, flatter Charnia fossils.

Dr Yorick Veenma, from Cambridge’s Department of Earth Sciences and the lead author of the study detailing the team’s discovery, said finding a 3D fossil from this archaic time has provided them with an entirely new perspective.

“When you see the same species preserved in a different way, you start noticing properties you hadn’t seen before,” Dr. Veenma explained.

“There May Be a Whole Undiscovered Community of These Very Early Organisms”

Although scientists have found a few fossils from this period, they are often from the same handful of sites. However, this is the first time one has been found in Norway. Dr. Veema said this shows that discoveries can be made “in less familiar places.”

The researchers also successfully identified other components of the ancient ecosystem that this Charnia fossil called home. Future efforts may reveal that it was one small part of a larger, ‘lost’ ancient ecosystem supporting a variety of complex life forms.

“There may be a whole undiscovered community of these very early organisms preserved up there,” Davies explained. “Weird little umbrella-shaped blobs, things that don’t fit with what people know from elsewhere.”

“There are a whole host of different things that were not known before,” the researcher added.

The study “Charnia and other late Ediacaran macrofossils preserved in turbiditic deposits of the Indreelva Member (Finnmark, Norway)” was published in Paleontology.

A Curtin University-led research team has successfully identified the mysterious origin of several 4,000-year-old 25-ton stones, which ancient architects used to construct Britain’s iconic Devil’s Arrows, as Birmingham Rocks in North Yorkshire, over 11 miles (18 kilometers) from the monument’s location.

The researcher behind the first-ever geological source identification of the ancient stone monument said the quarry’s distance and the work required to move such massive stones suggest the ancient architects intentionally selected the material used to construct Devil’s Arrows.

Unraveling the Mysterious Origin of the 4,000-Year-Old Devil’s Arrows

Announcing the discovery, the research team, which included scientists from the University of York, UK, noted that the famous stone pillars stand up to seven meters (22 feet) tall. The team also said the site is unusual because such alignments are rare in lowland settings. Still, researchers have struggled to locate the mysterious origin of the massive stone pillars used to create the over 4,000-year-old monument.

The Curtin-led team noted that previous studies determined that the stones used in Devil’s Arrows were transported to the site during the Late Neolithic or Early Bronze Age. This range means the site could have been constructed as early as 2000 BC.

Lead author Dr Anthony Clarke, from Curtin’s School of Earth and Planetary Sciences, noted the significant challenges with moving the stones over such difficult terrain.

“Each stone weighs more than 25 tonnes, so moving them would have required incredible planning, coordination and engineering skill,” the researcher explained.

Dr. Clarke also highlighted the value this effort suggests these ancient Britons “placed real importance” on the material used in the monument’s construction and the landscape itself.

“It wasn’t just about convenience – the location the stones came from likely held meaning for them,” the researcher explained.

Low Impact Sampling Method Confirms Ancient Stone’s ‘Fingerprints’

To unravel the ancient site’s mysterious origin, the researchers placed tiny pieces of low-adhesion tape on the stones and then removed them. The team said this “low impact” sampling process collected several tiny mineral grains on the tape without measurable damage to the ancient monuments.

According to the statement announcing their solution to the Devil’s Arrows origin mystery, the team performed an analysis of the “fingerprints” of the selected grains. The results matched material from Brimham Rocks.

Critically, the mystery’s solution also addressed the possibility that glacial movement or other natural processes moved the stones over the needed distance. Instead, the team said their results demonstrated that “the stones were intentionally transported by people.”

“Our research shows these stones weren’t simply taken from the nearest available source – they were deliberately chosen from a challenging landscape 18 kilometers away,” Dr Clarke said.

Clarke also said that the results eliminate the nearer site of Plimpton Rocks, which “had previously been identified as the probable source of the stones.”

“Our findings instead point to Brimham Rocks, showing that prehistoric builders transported these enormous stones significantly further than thought,” he explained.

Solving Similar Stone Monument Origin Mysteries

After discovering the mysterious origin of the 4,000-year-old pillars, Dr Clarke said the team will apply its low-impact sampling method to similar stone monument origin mysteries. The team also hopes to conduct future “targeted excavations” at the Devil’s Arrows site and the newly identified source.

Dr. Clarke said that analysis might help explain how these ancient architects moved the massive stone pillars several miles over rugged terrain over 4,000 years ago. The research said the work could also unravel “how these extraordinary monuments were constructed.”

Co-author Dr Jim Leary from the University of York echoed Dr Clarke’s sentiments, while also suggesting that the team’s findings ‘reshaped’ how researchers understand the art of prehistoric monument-building.

“These results show that ancient communities were making deliberate and meaningful choices about where their stones came from,” Dr Leary explained.

The York researcher said their solution to the Devil’s Arrows origin mystery also “highlights the importance of landscape and shared belief systems, as well as the remarkable effort involved in transporting and raising stones of this size.”

The study, “Deliberate Prehistoric Sourcing of the Devil’s Arrows, Britain’s Tallest Stone Row,” was published in the Proceedings of the Royal Society.

Chinese scientists at the Beijing Institute of Technology have run satellite proximity simulations to extend potentially hostile observation of U.S. space assets in Geostationary Earth Orbit (GEO), seemingly inching both countries closer to a potential war in space.

Although the new simulations focus on orbital adjustments to extend observation times and increase proximity to U.S. satellites, including critical missile warning and other space defense-oriented systems, Chinese scientists also plan to integrate reinforcement learning methods into future space assets to give satellites even more independence from human operators.

Study Includes Accusations of Cold War in Space Activities

In the 20th century, the concept of war in space remained mostly in the realm of science fiction, as depicted in popular films like Star Wars. Today, advances in space access, orbital maneuvering technologies, and weapons systems have made the possibility of a future conflict in space a very real security concern, and several nations engage in espionage using reconnaissance spacecraft to obtain information on valuable defense targets in Earth’s orbit.

According to the authors of the new study, “acquiring multi-aspect payload information of non-cooperative targets to infer their functions and mission statuses is of great significance for space security assessment.”

The study authors highlight a series of relative motion configurations that modern spy satellites employ, including fly-around, hovering, and drifting flight. They also point to real-world “adversarial” U.S missions they suggest were designed to gather intelligence on their GEO defense assets.

“Since 2014, the US GSSAP (United States Geosynchronous Space Situational Awareness Program) satellite has carried out hundreds of maneuvers and has conducted close observation operations on dozens of normally working satellites near GEO orbit,” the Beijing University of Technology scientists write.

The study authors also include a specific July 2021 accusation, where they charge that “the U.S. satellite ‘USA-271’ deliberately approached the operational ‘Practice 20’ satellite in geostationary orbit and flew in close proximity.”

In an email to The Debrief, a U.S. Space Command Spokesperson did not address the specific incident or the accusations of “dozens” of similar operations, but offered some insight into the agency’s thinking.

“USSPACECOM, working with allies and partners, plans, executes, and integrates military spacepower into multi-domain global operations in order to deter aggression, defend national interests, and when necessary, defeat threats,” the spokesperson told The Debrief, adding that “we have nothing additional to add in response to the article.”

Getting Closer to Adversarial Satellites and Extending Observation Time

In a step toward potential dogfights between satellites, the Chinese scientists looked at several challenges faced by current spy satellites.

For example, they explain, since most spacecraft observation cameras are mounted in a fixed position, “frequent large-angle attitude maneuvers are time-consuming and consume substantial fuel.” The researcher also noted that several different angles and approaches could yield different categories of intelligence data.

However, changing angles and orbital planes requires fuel, an extremely limited resource in GEO. Therefore, the researcher accounting for all the variables required to gather intelligence on adversarial spacecraft as efficiently as possible “has become a key bottleneck in enhancing space situational awareness capabilities.”

To find an optimized solution, the team designed what they called a “waypoint trajectory planning scheme” and a “multi-impulse maneuver strategy” using a common game-theory tool called “minimum integral squared control” theory. Unlike previous research aimed at extending spy satellite observation time and fuel efficiency, the Chinese scientists said their use of sequential coalition game theory “is introduced for the first time into the multi-model combined observation problem.”

Next, the researchers designed a “game tree.” A press release said this approach lets the spacecraft select the “optimal combination of initial motion points and close-range operation models at each stage under minimum fuel constraints, thereby generating an optimal observation strategy sequence.”

Finally, the researchers ran simulations to see whether their approach improved sensor observation times and field of view while reducing fuel use.

Successful Simulations and Future Reinforcement Learning Plans

As hoped, the Beijing University of Technology team said their simulations supported the theories. Specifically, the study authors said the simulations showed that their spacecraft efficiency algorithm “can successfully generate a multi-model combined observation strategy sequence under minimum fuel constraints.”

“The effective observation time increases with larger observation distances and field-of-view angles, and reducing the model configuration size also contributes to improved observation performance,” they explained. The study authors also said that the simulation results “demonstrate that the algorithm can successfully generate the optimal combined observation sequence under minimum fuel constraints.”

When discussing next steps, the Chinese scientists said they will explore optimal initial points to further improve maneuver efficiency. They also plan to explore a “reinforcement learning method,” suggesting future spacecraft could learn and adapt to evolving conditions to further enhance their cold war in space information-gathering capabilities.

Study’s War in Space Implications “Extends Beyond any Single Algorithm”

To understand the potential implications of the Chinese study, including its impacts on a potential future war in space, The Debrief reached out to former U.S. Air Force officer Shelli Brunswick, CEO and Founder, SB Global LLC.

According to the author and futurist, the Chinese team’s research matters not just because it proves China has deployed a “new operational surveillance capability.” Instead, Brunswick said that the work is significant because it “illustrates how sophisticated coordination and optimization could make spacecraft observation more efficient, persistent, and strategically useful.”

The Blue Marble Space Visiting Scholar also told The Debrief that the work “should not be interpreted as demonstrating a complete pursuit-and-evasion capability against a spacecraft that is actively responding,” since the work assumes a stationary target without maneuvering capabilities. Still, Brunswick noted, the Chinese framework “shows how game-theoretic planning could help an observing satellite gather information from multiple angles while managing limited resources.”

When discussing the potential implications for the broader U.S.-China space-security competition, including how such enhanced spacecraft could lead to more activities that could be construed as hostile, the space strategist said this area of research “extends beyond any single algorithm.”

“As rendezvous and proximity operations become more sophisticated, the line between inspection, space situational awareness, intelligence gathering, and potentially threatening behavior becomes increasingly difficult to interpret,” she explained.

When suggesting what potential strategic responses the U.S. and its allies might employ in the emerging cold war in space, Brunswick told The Debrief that they should include “more resilient architectures, improved space-domain awareness, clearer expectations for close approaches, stronger communication mechanisms, and deeper coordination with commercial and international partners.”

“The challenge is not simply detecting another spacecraft—it is understanding capability and intent early enough to respond responsibly and effectively,” Brunswick explained.

Almost exactly one year ago, investigative journalist Pablo Torre, host of the Pablo Torre Finds Out podcast, exposed alleged efforts by Los Angeles Clippers billionaire owner Steve Ballmer (a former Microsoft Executive) to circumvent the NBA’s collective bargaining agreement by funneling undisclosed millions of dollars to All-Star player Kawhi Leonard.

Now, the league’s year-long investigation has concluded, revealing even more violations than the Pulitzer Prize– and Edward R. Murrow Award-winning podcast series uncovered over more than a dozen episodes.

The investigation’s conclusion also saw league Commissioner Adam Silver levy drastic punishments, including the loss of five future draft picks and suspensions for Ballmer and others in upper management. The team also received a league-record $30 million fine.

As the fallout from the historic cheating scandal and threats of legal action from the team owner continue to make headlines, The Debrief asked experts to help explain the mindset and decision-making of people like Ballmer, who operate in the rare universe of someone reportedly worth over $140 billion.

Decision Making at the Top

To understand how such a wealthy and successful individual could break the rules as brazenly as the 35-page public report from investigating law firm Wachtel, Lipton, Rosen, and Katz lays out, The Debrief asked Patrick Vishy, a behavioral finance educator specializing in decision-making and risk perception for high-level investors and traders, to offer some insight.

“People at the $100 billion level like Steve don’t see risk the same way we do, because survival is no longer on the table,” Vishy explained. “It now becomes a scoreboard amongst his industry peers.”

The high finance educator also suggested that many of Balmer’s fellow owners likely “respected the creativity behind his rule-breaking.” However, Vishy noted, they were likely less enthusiastic about “how he allowed himself to get caught.”

Although the No Nonsense Courses finance educator does not have a psychology background, he did point to two well-documented ‘internal reasons’ why he believes that “Steve in particular is bending the rules the way he has and will probably continue to.”

Invincibility Bias

The first is a concept the educator called “Invincibility Bias.” A search of relevant psychological documentation found that this bias, which is more often referred to as an “invulnerability bias,” is typically associated with the normal teenage developmental idea of being immortal or invulnerable to danger.

In a November 2025 story for Psychology Today, Dr. Su Yeong Kim, Ph.D., described invulnerability bias in teens as “the quiet conviction that ‘nothing bad will happen to me.’”

“This mindset differs from confidence, which acknowledges risk but trusts in one’s ability to handle it,” Dr. Kim explained. “Invulnerability, by contrast, denies risk altogether.”

Although the Clippers owner is well past his teenage years, Vishy told The Debrief that it is not uncommon to encounter this mindset in extremely high-net-worth individuals like Ballmer.

“When somebody takes asymmetrical risks for decades and constantly wins, their brain internalizes the belief that standard rules are meant for others, not them, and they can engineer their way out of any consequence,” the finance educator explained.

The Level Playing Field Fallacy

The second mechanism Vishy suggested that may have affected Balmer’s decisions to cheat is called “The Level Playing Field Fallacy.” While most online citations say the concept originated in sports, its primary modern use appears to be in finance.

When explaining how it applies to this situation involving both worlds, Vishy told The Debrief that “Steve can reasonably assume rival team owners are bending the rules as well and does not want to put himself at such a voluntary disadvantage by being 100% clean.”

As a matter of fact, Vishy added, for someone at Ballmer’s level of success, “it would seem absurd even.”

“At his level of wealth, societal ethics no longer register as a meaningful constraint,” the finance educator explained. “His competitive drive won’t allow him to constantly play from behind like that.”

“These two things lead to ego-driven moral disengagement,” Vishy added. “When you’re used to being the smartest guy in the room, the inner monologue regarding internal ethics shifts from ‘Is this allowed?’ to ‘Is this necessary for my goal?’ plain and simple.”

Why Do Subordinates Go Along?

A thorough examination of the Wachtel report reveals more than a single, uber-wealthy individual deciding that the rules don’t apply to him and that everyone else is cheating, so why shouldn’t he? Instead, the year-long investigation uncovered several cases of fraud involving at least four outside companies and a handful of top Clippers executives all working in concert to facilitate the deception.

While the financial motivations for companies trying to win contracts or unscrupulous agents like Kawhi’s notorious “Uncle Dennis” (who the league has banned for five years as part of its ruling) seem relatively straightforward, the mindset of high-level Clippers employees is not as clear.

According to the investigation’s findings, several Clippers higher-ups, including the team’s President of Business Affairs, Gillian Zucker, and LA’s President of Basketball Operations, Lawrence Frank, not only repeatedly and blatantly violated the league’s salary cap circumvention rules, but also preemptively constructed a series of cover stories just in case a future investigation ever took place.

After a 12-month suspension for Zucker and a 6-month suspension for Frank, The Debrief contacted Giulia P. Davis, a 15-year management consulting veteran and former equity partner who works with Fortune 500 clients to understand the “go along” mindset that may have permeated the entire organization.

The People Involved Often Don’t Experience Themselves as Breaking the Rules

According to the Founder of Mycelia Therapy, the reasons people working under a Steve Ballmer-type go along with rule-breaking behaviors often go beyond a simple fear of losing their jobs. Instead, Davis explained without directly addressing the Clippers fiasco, “there’s a pattern I find interesting in situations like this.”

“The people involved often don’t experience themselves as breaking the rules,” the Licensed Marriage and Family Therapist (LMFT) told The Debrief. “They believe they’ve found a way to work within them.”

As an example, the veteran management consultant pointed to the language used by individuals who find themselves in these situations

“The defense is often not ‘we didn’t do this,’ but ‘what we did was legal,’ Davis explained.

How People Convince Themselves that They Are Not a Rule Breaker

When exploring potential motivations for high-level subordinates, Davis also told The Debrief that people who go along with bad behavior at these levels don’t always start out with improper intentions. Instead, the therapist noted, advisors, lawyers, and outside consultants “will sometimes come into an organization looking for solutions.”

“While saying no might not be their ultimate goal, they must determine whether something can work,” she explained.

The finance world veteran also noted that simple inertia and lack of consequences can lead to a more permissive mentality.

“When all of those people in the room are going to get paid regardless of what happens, it’s quite surprising how easily one can lose sight of a much larger issue,” Davis explained, adding, “that’s why I believe the primary issue might be systemic (i.e., structural), not solely due to the individual’s nature.”

For example, Davis said it is possible for someone in a leadership or ownership position like Ballmer to “develop a culture within which all individuals technically comply with their respective roles, yet no member of the organization will have sufficient separation or motivation to say, ‘I did my job, but in doing so, I defeated the intent of this policy.’”

“It is that point in the decision-making process where ego appears,” Davis said.

“In other words, once you see yourself as being a person who follows the rules, it is far easier for you to deny your own admission, as you are now defending a personal identity,” Davis concluded.

Archaeologists conducting a new series of excavations at the ancient Turkish city of Smyrna have uncovered three previously hidden rooms and a 1500-year-old Late Antiquity theater that earlier efforts had missed.

The new excavations, which took place in Izmir’s historic center, also uncovered a series of ancient paintings that had remained hidden for over a millennium, along with a Roman-era water channel that, unlike similar structures, seems to stop before reaching any nearby natural springs.

1,500-Year-Old Hidden Rooms, Ancient Paintings, and a Lost Theater

According to a statement from the Izmir Metropolitan Municipality, the work, which was  “conducted on behalf of Izmir Katip Celebi University with permission from the Ministry of Culture and Tourism,” expanded on previous excavations at the same site. However, the new excavation effort uncovered several previously unknown finds.

First, the archaeology team came across three new hidden rooms, or “spaces,” in an area where previous efforts had uncovered an ancient mosaic floor. According to the excavation team, two of the new spaces also contained mosaic floors. However, the third newly discovered space featured a marble floor.

Second, the research team uncovered what they described as a “theater area.” Researchers had not identified the theater during previous excavations.

Third, the Izmir authorities described a series of ancient wall paintings as the most visually striking component. According to the Metropolitan Ministry’s statement, the previously undiscovered wall paintings were placed around the Agora and the theater.

“This is the first time we have found wall paintings in these spaces,” explained Prof. Dr. Akin Ersoy, faculty member of the Turkish-Islamic Archaeology Department at Izmir Katip Celebi University and the head of the latest excavations.

“We Had Never Come Across Anything Like This in the Agora of Smyrna”

When dating the site, Prof. Dr. Ersoy said cities in the region underwent significant structural changes after the division of the Roman Empire at the end of the 4^th century A.D. These changes allowed the excavation team to date the site to sometime between the fifth and sixth centuries A.D. This ancient date makes the site over 1,500 years old, placing it in the period historians call Late Antiquity.

When discussing the architectural style of the new excavations, the team leader said they share some features with the Terrace Houses found at the ancient city of Ephesus. The research said the similarities suggest that the newly discovered structures may have served a public function. Still, he noted, these discoveries were unexpected.

“Until now, we had never come across anything like this in the Agora of Smyrna or around the theater.”

Given the likely historical period of the site’s construction and use, the research team also noted that the newly uncovered hidden room spaces and ancient paintings will offer previously unavailable insights into Smyrna’s transformation away from Roman influence.

150 Yards of Roman-Era Water Channel Also Unearthed

During the excavations, the team also traced a section of an ancient Roman-era water channel. The researchers suggested that the ancient channel carried water for roughly 2,000 years.

Although Roman-era water channels were typically connected to natural springs, Ersoy said the team has traced roughly 150 yards of channel and has yet to find its source. The team leader suggested a spring may lie just south of the site, near the Namazgah Bath and Kursunlu Mosque.

Future excavations are hoped to uncover more evidence of the ancient spring and perhaps even more hidden rooms and artworks left behind in the 1500-year-old city.

A University of St. Andrews-led research team has proposed that the red wavelengths of flickering light emitted by early human ancestors’ campfires helped reprogram the human brain to boost social and verbal communication, leading to modern language and storytelling behaviors found only in humans.

The team, which included researchers from Dartmouth College, said the study builds on earlier theories linking fire and language to the extra hours it added to the day.

However, their findings suggest that the biological changes caused by fire use may have enabled complex language as much as fire-associated behavioral changes, accelerating the evolution of verbal communication away from the ape-like systems still used by modern apes toward more complex, “uniquely human” interactions.

Researchers Wondered if Firelight Reprogrammed the Human Brain

Catherine Hobaiter, a Professor of the School of Psychology and Neuroscience at the University of St Andrews and the lead author of a paper detailing the team’s idea, said she has always been fascinated by the origins of language.

“What was the first word?” the professor asked. “The first story?”

Unfortunately, Professor Hobaiter noted, many questions about the origin of humanity’s complex and diverse forms of verbal communication remain unanswered.

Some earlier research has explored a possible link between the first spoken words and the advent of controlled fire use. However, the team notes that most studies have focused primarily on the extra hours of practical light added to the end of each day.

Curious whether other biological mechanisms also contributed to the evolution of language and complex storytelling behavior, Professor Hobaiter and colleagues examined the effects of sitting around a campfire to see whether the emitted light could reprogram the human brain.

Potential Effects of Red Wavelengths and Flickering Lights

First, the team noted that one potential catalyst emitted by firelight that could help reprogram the human brain for complex language is the color of the light wavelengths emitted by campfires. Specifically, Hobaiter and colleagues noted that campfire light emits almost no blue wavelengths but instead mostly in the visible red spectrum.

Many modern studies have focused on the potentially adverse effects of exposure to blue light wavelengths from modern technology on sleep patterns and overall health. Conversely, the paper’s authors described the red wavelengths emitted from fire as ‘uniquely suited’ for human socializing, “allowing an extension to the day without negatively impacting sleep.”

Another component of firelight the study authors suggest could have reprogrammed the human brain for speech is the way a campfire behaves. Unlike a modern, steady light source, the authors noted that firelight “flickers.”

Hobaiter and colleagues said that neurons in the human brain synchronize firing patterns with external flickering lights. For example, flickering lights in movies and TV shows often come with warnings against possible neurological effects on vulnerable viewers. The research team said this mechanism might also help synchronize the behavior of those seated around the campfire, resulting in a much deeper feeling of connection.

Finally, the researchers noted that firelight emits infrared wavelengths, which may have also contributed to helping firelight reprogram the human brain for complex verbal communication.

Are We the Storytelling Ape?

When discussing the potential impact of their proposal, study co-author Nathaniel Dominy, the Charles Hansen Professor of Anthropology at Dartmouth College, said many of the chemical properties have been well researched. However, Professor Dominy also notes that understanding the properties of light that capture our attention and focus, thereby instilling “harmony and cooperation,” has received far less attention.

“Measuring these features is an exciting part of this project,” the study author added.

Professor Hobaiter agreed, while also noting the conundrum scientists face when explaining why humans speak, when “decades of research with other species has shown us that you don’t need language to learn from each other, to organize where and when to forage, to learn cultural knowledge about tools and songs, to co-ordinate hunting, or navigate social politics.”

“While other species share all these skills, there is a fundamental puzzle: we struggle to find evidence of key differences between human and ape communication,” Professor Hobaiter explained. “And yet, we are surrounded by evidence of human distinctiveness. For all their incredible, rich communication and cultures, no other ape is inventing algebra, writing King Lear, or heading out into interstellar space.”

“So, it’s especially exciting to be able to generate testable predictions, to be able to ask if, at the end of the day, we are the storytelling ape,” the professor added.

The paper “Firelight and the Origins of Spoken Language” was published in Proceedings of the Royal Society.

An international research team has announced the first-ever successful observation of gravity’s effect on a falling quantum object, demonstrating a connection between gravity and the quantum world first predicted by Albert Einstein.

The research team said the result does not unify quantum mechanics and gravity, nor does it prove that gravity is a quantum phenomenon.

However, the researchers said their study offers experimental support that Einstein’s equivalence principle, a fundamental concept at the heart of the famed scientist’s theory of gravity, remains consistent with matter in the quantum world.

Unifying Einstein’s Theory of Gravity with Quantum Mechanics

When physicists want to describe nature, they rely on two distinct sets of rules. Einstein’s theory of gravity explains the mechanics of large-scale phenomena like stars and galaxies. Conversely, quantum mechanics helps scientists characterize the behavior of extremely small objects. Still, finding a scientific bridge uniting the two sets of rules has proven elusive.

“These two pillars of modern physics have so far eluded all attempts at a unified theoretical framework,” explained Professor Ron Folman from Ben-Gurion University of the Negev and the lead author of the new study.

Einstein did, however, identify one mechanism where the two worlds meet. Called the equivalence principle, the concept says that gravity should effectively disappear for an observer in free fall. For example, NASA simulates zero-gravity environments by flying astronauts in a plane, making successive rising and falling parabolic arcs. During the short periods of falling, the astronauts briefly experience ‘weightlessness” due to the equivalence principle.

Curious if the same phenomena would apply to the quantum world, the research team, which included Nobel Prize-winning physicist Professor Sir Roger Penrose, designed experiments. According to a statement announcing the research, the team hoped their setup would allow them to measure a “distinctive change in the quantum properties of atoms as they fell under gravity.”

Experiments Show Gravitational Pull Affecting Quantum Objects

To search for gravity’s effect in the quantum world, the researchers created clouds of rubidium atoms cooled to just above absolute zero. The researchers used a specially designed atom chip that allowed the team to manipulate the ultracold rubidium atoms.

Next, PhD student Or Dobkowski and colleagues used microwave pulses to place the atoms in quantum superposition. This unique quantum state lets each atom travel down two paths at once.

Using tiny electrical wires embedded on the specialized chip, the researchers generated tunable magnetic fields. The researchers said the field’s precision tunability allowed them to apply an upward force to one half of the atomic wave. For this experiment, the team created a magnetic field at the precise strength needed to counter gravity, effectively holding that half of the wave stationary relative to Earth.

After suspending the first half of the wave, the team used a magnetic pulse to lift the second part. Then, the team switched to a state almost unaffected by the magnetic field, allowing it to fall under gravity.

Once the second half completed its fall, the team used magnetic fields to reunite the two halves. When reunited, the two halves of the atomic wave interfered with each other. The researchers said that interaction allowed them to “measure the tiny difference in quantum phase accumulated while one was falling and the other was held still.”

“The phase measured in the new experiment is the same as the one predicted when Einstein’s principle is applied to such a quantum wave,” they explained.

“One of the Most Fundamental Questions in Physics”

When discussing the results, the research team said their result should not be construed as proof that gravity is quantum. The results also do not unite gravity and quantum mechanics. However, Folman noted, “this complex experiment gives more hints as to how such a unification may be achieved.”

Study co-author Professor Vlatko Vedral from the University of Oxford’s Department of Physics agreed, while also noting that their experimental results successfully demonstrated Einstein’s equivalence principle’s consistency with quantum mechanics, which alone provides an experimental connection between quantum physics and Einstein’s theory of gravity.

“This experiment pushes quantum mechanics into one of its most intriguing frontiers, gravity, and shows that, once again, its predictions hold,” Professor Vedral explained.

The professor also noted the experiment’s combination of hard experimental data with “a far-reaching theoretical interpretation, about one of the most fundamental questions in physics: How can gravity (described by Einstein’s theory of relativity) and quantum theory be unified into one understanding of the universe?”

The study “Observation of the quantum phase of free fall and the consistency with the equivalence principle” was published in Science Advances.

Officials from Turkey’s Ministry of Culture and Tourism working at Karahan Tepe, a “significant parallel site” to the enigmatic Göbekli Tepe, have announced the discovery of a unique stone sculpture depicting a human figure riding a leopard.

Ministry officials said the 70-centimeter-tall “composite sculpture,” likely carved thousands of years before the first organized human societies, “opens new questions” about the ancient Neolithic artist who created it.

The discovery also offers insights into the sophistication of the society and the types of artistic expression taking place thousands of years ago in this archaeologically rich region of southeastern Turkey, according to a recent Yenisafak news agency report.

11,000-Year-Old Composite Sculpture Found at “Parallel Site” to Göbekli Tepe

When most people think of ancient megalithic structures, well-known archaeological sites like the Egyptian pyramids, Stonehenge, and Machu Picchu likely come to mind. Critically, all those impressive feats of ancient engineering were accomplished after the generally agreed-upon formation of humanity’s first societies.

Those attitudes began to shift after the relatively recent discovery of Göbekli Tepe in southeastern Turkey. Famous for its massive stone pillars and lifelike animal sculptures found throughout much of the site, the site’s construction has been scientifically dated to between 11,500 and 12,000 years before present. That date places this impressive site and its artwork’s creation thousands of years before those first human societies.

While researchers continue to excavate Göbekli Tepe, they have also unearthed several historically rich sites in the same region. That includes the nearby Karahan Tepe, which has been dated to a few hundred years after its more famous neighbor.

“Composite Sculpture” Represents Style Not Previously Identified in Region

According to the ministry, Karahan Tepe lies approximately 30 kilometers from Göbekli Tepe. The historic sites are part of the larger Taş Tepeler archaeological project. That effort includes a cluster of Stone Hills sites previously dated to the Neolithic period more than 11,000 years before present.

When Turkey’s Culture and Tourism Minister Mehmet Nuri Ersoy announced the discovery, he described the ancient artwork as a “composite sculpture.” The Minister said the find, which he also described as 11,000 years old, represented a style not previously encountered at the ancient site, near Şanlıurfa.

The minister said the unusual sculpture was found during ongoing excavations this year. Instead of resting inside a majestic monument like the Göbekli Tepe sculptures, the leopard-and-man statue was found resting on a bench along the wall of a circular structure “roughly three meters in diameter.”

Notably, the structure’s floor was paved with flat stones. The ministry said this suggests a sophisticated level of deliberate architectural planning “during an era predating the emergence of cities and written records.”

Find “Opens the Door to New Questions About the Earliest Periods of Human History”

When discussing the discovery’s significance, the ministry pointed to the volume of monumental structures and elaborate artworks found in the region. They also noted the value of artifacts representing humanity’s transition “between mobile hunter-gatherer existence and settled agricultural life,” which “challenge previous assumptions about the timeline of complex social organization.”

“While Göbeklitepe has drawn international attention since the 1990s for its T-shaped pillars and animal carvings, Karahantepe has emerged as a significant parallel site since excavations began there in 2019,” the announcement explains.

After highlighting Turkey’s ‘Heritage to the Future’ initiative, which supported the effort, Minister Ersoy said the ancient statue’s discovery “opens the door to new questions about the earliest periods of human history” and would resonate throughout the scientific community.

Now that NASA’s Nancy Grace Roman Space Telescope is on its way toward its Lagrange Point 2 (L2) destination, more of its mission goals are coming into focus, including the possibility that it could detect an Earth-like planet orbiting a star like our own Sun using gravitational microlensing.

The Roman team said such a detection could identify targets for the proposed Habitable Worlds Observatory project, including scanning their atmospheres for signs of extraterrestrial life.

Searching for Another Earth with the Nancy Grace Roman Space Telescope

In NASA’s mission fact sheet, Roman’s planners pose several questions. These include: 

• How common are solar systems like our own?
• What kinds of planets exist in the cold, outer regions of planetary systems?
• What determines the habitability of Earth-like worlds?

Although scientists have used several methods to detect exoplanets, including Earth-like planets, Roman will employ three. These include the transit method, microlensing, and direct imaging. NASA said the combination of approaches will allow mission scientists to conduct a “sweeping search expected to uncover around 100,000 new exoplanets — a staggering leap compared to the nearly 6,200 currently known.”

“It is hoped that Roman will discover thousands of new exoplanets and significantly expand our knowledge of the diversity of planetary systems in our Galaxy,” explained Associate Professor Edita Stonkutė, an astrophysicist at Vilnius University unconnected to the Roman team, in a statement emailed to The Debrief.

Microlensing Can Reveal Earthlike Planets Orbiting Sunlike Stars

Most exoplanets have been detected by the dimming of their host star when they transit between it and Earth, giving the transit method its name. Roman plans to use that same method for most of its larger planetary detections. However, among the expected tens of thousands of transit-method detections, mission planners expect a small but sizeable percentage to come from microlensing.

NASA said the “light-bending” microlensing phenomenon occurs when two distant stars “align closely from our vantage point.” Due to the strength of the nearer star’s gravity, the light from the more distant one is “warped” around the nearer one, essentially focusing it very briefly for a distant observer.

“If the alignment is especially close, the nearer star acts like a cosmic lens, focusing and magnifying light from the background star.” Professor Stonkutė explained. “By analysing these changes, astronomers can determine that the planet exists and estimate its mass and orbital characteristics.”

Critically, Professor Stonkutė also noted that microlensing can occur with objects other than stars, including exoplanets.

“This is Precisely Where Roman Has the Edge”

Using its Wide-Field Array, Roman will monitor hundreds of millions of stars. NASA said the observatory will monitor these target stars for “tiny surges in starlight” that typically signal a microlensing event.

Although the transit method is employed to detect larger exoplanets, NASA noted that microlensing “specializes in finding planets like those in our solar system.” The space agency added that this includes “worlds as lightweight as Mars in their star’s habitable zone or farther out.”

A star’s habitable zone is typically defined as the orbital plane where an exoplanet could sustain liquid water on its surface, a key ingredient for life as we know it.

Professor Stonkutė described microlensing as “particularly valuable” since it can detect planets that are difficult to spot with other planet-hunting methods. The professor said this includes “small Earth-like planets located far from their star.” The Roman team hopes to find “more than 1,000 microlensing planets.”

The professor warned that “most microlensing events cannot be predicted in advance.” As a result, telescopes need to actively scan large areas of the sky to increase the chances of a microlensing detection

“This is precisely where Roman has the edge over other telescopes that have searched for exoplanets using different methods,” the professor added.

A “Stepping Stone” Toward NASA’s Habitable Worlds Observatory Concept

While Roman is tasked with directly imaging exoplanets, finding another Earth around a Sun-like star will still require an indirect detection, most likely from a microlensing event. However, the Roman team notes that their observatory “will provide a crucial stepping stone for NASA’s Habitable Worlds Observatory concept.”

According to the space agency, that “flagship” telescope, still awaiting final approval, “would be designed to photograph Earth-like planets for the first time ever.”

Roman may also be able to scan the atmospheres of planets detected with the transit method. The space agency said Roman “would also look for signs of life called biosignatures by measuring atmospheric gases like oxygen and ozone that could signal the presence of living things.”

Scientists at the University of Colorado at Boulder’s Cooperative Institute for Research in Environmental Sciences (CIRES) have discovered that some microbes in Antarctica’s soil don’t exist anywhere else on Earth, upending the long-held belief that microbes move freely around the planet and inhabit many regions.

The researchers behind the discovery said understanding that some microbes are endemic to Antarctica’s soil challenges previous assumptions and offers valuable insights for future research and present-day conservation efforts.

Microbes in Antarctica’s Soil Live in an Extreme Environment

Announcing the findings, study leader and postdoctoral researcher Nick Dragone and co-author Noah Fierer, a CIRES Fellow and Director of the Center for Microbial Exploration, noted that scientists have always assumed that microbial species were widespread.

“There is a long-standing assumption in microbiology that ‘everything is everywhere,’” Dragone explained.

That’s because, unlike plants and animals, which are generally restricted to certain global zones or latitudes, microbes are highly mobile. For example, a simple updraft could propel microbes into an atmospheric jet stream, then deposit them hundreds or even thousands of miles away.

Still, Dragone and Fierer propose that, given Antarctica’s remote location, if there were a spot on Earth containing species unlike the rest of the globe, it would be on the planet’s southernmost continent.

“If we do find we’re looking for endemic microorganisms, a good place to start is Antarctica, because it’s an entire continent that is geographically isolated, ” Fierer said.

The study coauthor also noted that the unique conditions found in Antarctica’s soil aren’t usually found in other soil environments. “[Being] cold is the obvious one,” Fierer said, “but also super dry; Antarctica is a desert.”

Comparing 100 Antarctic Strains with 500 Worldwide Strains

Instead of starting with any microbial species, the CIRES team focused on bacterial strains within the Arthrobacter group. First, these strains grow well in lab conditions, which was critical to the team’s experiments. Second, Arthrobacter group bacterial strains are found in diverse environments ranging from the tropics to Colorado, and most critically, to Antarctica’s soil.

Byron Adams, professor of biology at Brigham Young University and a co-author of the study, said the species is widespread, but also diverse.

“Arthrobacter as a group may be found all over the planet, but when we look closely at individual strains, just like penguins, Antarctica clearly has its own distinctive biological history,” the professor explained.

To start, the team collected soil samples from Antarctica. They also collected comparison samples from similarly cold, arid regions like the Tibetan Plateau, Svalbard in the Arctic, and Chile’s Atacama Desert.

When examining the sampled soils, the team tested over 100 Antarctic bacterial strains and 500 worldwide strains.

Dragone and Fierer both noted that the research was made possible by “long-term collaborations among international research teams who have spent decades collecting samples across the continent for various projects.”

Genetic Sequencing Finds 90% of Antarctic Microbes are Endemic

After sequencing the genomes of the Arthrobacter strains found in samples from Antarctica’s soils, the team compared them with worldwide strains. For the worldwide species, the team obtained genomes from international research databases.

As hoped, the genetic comparison found species in Antarctica’s soil that were not found anywhere else in the world. Perhaps even more shocking, 90 percent of the Antarctic strains they’d sequenced were completely endemic, with no matches anywhere in the world.

Fierer said previous studies had identified “a few endemic microbes found in very specific environments.” However, the researcher also noted that finding such a large and unexpected number of endemic microbial species “does suggest there could be some in other locations.”

“[Determining] whether other microbial groups show these patterns is a good direction to go,” Fierer added.

Next, the team ran a follow-up experiment to see whether the endemic Antarctic strains showed signs of adaptation to the local, extreme environment. This included growing strains of the collected Antarctic Arthrobacter strains in the laboratory. Critically, the team mimicked the continent’s harsh environmental conditions.

First, the experiments showed that the strains collected from Antarctica’s soil were extremely resilient. They also grew more slowly than non-endemic strains. The team suspects these results show that Arthrobacter strains “are uniquely adapted to Antarctica.”

“We already knew that a broad diversity of microbes can survive the inhospitable conditions of Antarctica,” Fierer said. “Now we know that some of those microbes are also unique to Antarctica and are uniquely adapted to life on the southern continent.”

“Some of Antarctica’s Most Distinctive Species are Microscopic”

When discussing the implications of their findings, Adams pointed to a potential shift in public perception of what species diversity means.

“We tend to think of biodiversity in terms of penguins, seals, and whales, the researcher explained, “but this shows that some of Antarctica’s most distinctive species are microscopic.”

Along with the study’s scientific and public relations value, the team said it “sets the stage for future research on microbial life in Antarctica.” They also noted that the findings will aid efforts to preserve Antarctica’s biological diversity, including its microbial species.

“Protecting Antarctic biodiversity also means protecting the biological history contained in a handful of soil,” Adams concluded.

The study, “Evidence for endemism and local adaptation in Antarctic soil bacteria,” was published in the Proceedings of the National Academy of Sciences.

When NASA announced that the new Nancy Grace Roman Space Telescope will perform its science duties from a point in space known as Lagrange 2, many observers noted that the space agency’s current state-of-the-art space observatory, the James Webb Space Telescope, shares this same orbital location.

Due to the extremely sensitive nature of both satellites and their sensors, and the irreplaceable scientific value they will provide in the future, it might seem natural to wonder whether these two space observatories are at risk of a deep-space collision.

Fortunately, that’s a very unlikely prospect, and here’s a look at all the space separating Roman and Webb—and how NASA will ensure the two observatories remain safely apart.

Many scientific satellites reside a little over 200 miles above Earth in an orbital plane called Low Earth Orbit (LEO). This proximity enables communication with Earth and offers the potential for future servicing missions.

For example, NASA’s groundbreaking Hubble Space Telescope orbits LEO at about 300 miles above Earth. This proximity enabled servicing missions that have kept Hubble delivering valuable scientific data for over three and a half decades since its 1990 launch. Still, LEO also limits which missions Hubble can undertake.

More recently, NASA launched JWST. However, unlike Hubble, Webb rocketed roughly one million miles from Earth before arriving at Lagrange 2. According to a NASA fact sheet detailing the Roman Space Telescope’s mission, this location offers several benefits over LEO.

“At L2, the gravity of the Sun and Earth, together with an object’s motion around the Sun, let it stay lined up with Earth as they orbit,” NASA explains, “allowing Roman to have a relatively steady orbit without using much fuel.”

NASA also notes that heat from Earth, the Sun, and the Moon has less impact on infrared telescopes designed to “see” heat. L2 also offers JWST and Roman, “a constant, unobstructed view of a wide swath of the sky.”

“Earth won’t block much of Roman’s view since it will be so distant,” NASA explains.

Is There a Danger of a Roman-JWST Collision?

Instead of sitting still at the heart of L2, NASA notes that Webb “traces out a large orbit around the actual L2 point.” For comparison, the space agency noted that JWST’s orbit around L2 is “much larger than the Moon’s orbit around Earth.”

Like Webb, the Nancy Grace Roman Space Telescope is also destined for L2. The new space telescope will also trace out an orbit around L2 rather than remaining comparatively stationary.

Because of the wide orbits of both spacecraft and the efforts of the mission’s controllers, NASA said the two valuable space telescopes “will easily be kept far apart.”

Five-Year Mission Could Stretch to Ten or Beyond with Refueling

Like previous NASA missions, Roman will have a primary lifetime and a backup plan if the observatory remains viable after the first mission ends. For Roman, both the primary and secondary missions are slated for five years, bringing the observatory’s planned potential lifetime up to a possible ten years.

Notably, several NASA missions have continued to deliver scientific data well beyond their planned primary and secondary missions. Perhaps the most famous example is Voyager 1. Launched in 1977, the interplanetary mission has since left the solar system and continues to return data from beyond the heliopause, an area of deep space over 14 billion miles from Earth.

When discussing what obstacles may result in a shorter mission profile, NASA said that “fuel is expected to be the mission’s life-limiting resource.”

“While NASA does not currently have an ability to service observatories at L2, Roman is designed to be refuellable,” they added.

Before NASA’s Nancy Grace Roman Space Telescope arrives at its Lagrange 2 destination and begins performing years of observations, the cutting-edge observatory that started life as a National Reconnaissance Office (NRO) spy satellite will deploy and calibrate its suite of instruments.

These include a primary mirror, a Wide Field Array sensor, and a Coronograph Instrument technology demonstration designed to block out starlight to enable direct imaging of exoplanets.

Here is a quick peek at those instruments, which will help Roman image exoplanets, search for signs of dark matter and dark energy, and add huge amounts of raw scientific data that will keep scientists busy for years to come.

Nancy Grace Roman Space Telescope Instruments: The Primary Mirror

Designed and built at L3Harris Technologies in Rochester, New York. Roman’s primary is 7.9 feet across (2.4 meters). That is the same size as the one on NASA’s legacy Hubble Space Telescope.

However, NASA said Roman’s main mirror, which weighs 410 pounds (186 kilograms), is just one-fourth the weight of Hubble’s, “thanks to major improvements in technology.” They also noted that the weight difference was critical to the Lagrange Point 2 mission’s viability.

The Wide Field Instrument

While the main mirror will gather light, Roman’s Wide Field Instrument, or WFI, will gather digital images of the cosmos. According to NASA’s mission fact sheet, the 300-megapixel infrared camera “will give Roman the same angular resolution as Hubble but with a field of view at least 100 times larger.”

“Using this instrument, each Roman image will capture a patch of the sky bigger than the apparent size of a full moon,” the space agency explained.

Unlike many telescopes designed to focus incoming light toward a central point, NASA said Roman is designed to “see the most detail in a ring around the center.” That’s because the WFI’s millions of detectors are laid out in an arch shape. The space agency said this design “helps Roman capture a much wider area with equally sharp imaging and also lets both instruments operate simultaneously.”

Due to the hardware and software improvements, NASA said the WFI will gather data “up to 1,000 times faster than Hubble. When Roman’s five-year mission is completed, mission planners said they expect to gather “up to 20,000 terabytes (20 petabytes)” of data.

“Its sweeping cosmic surveys will help scientists discover new information about planets beyond our solar system, untangle mysteries like dark energy, and map how matter is structured and distributed throughout the cosmos,” the agency said when detailing WFI’s capabilities, adding that the mission’s “broad, crisp view will produce an extraordinary resource for a wide range of additional investigations.”

WFI’s Detectors

In a fact sheet, NASA said that the detector array at the heart of Roman’s WFI contains 18 “saltine cracker-sized” detectors. The space agency also said that each detector contains roughly 16.8 million tiny pixels (for a total of 300 million), “providing the mission with exquisite image resolution.”

Each cutting-edge detector comprises millions of photodiodes, which convert light into electrical current. NASA said this number of detectors, made from mercury-cadmium-telluride photodiodes (sensors that convert light into an electrical current), provides “one for each pixel.”

The space agency also noted that individual detectors are secured to a silicon electronics board that will help process the light signals using indium. Unlike steel, indium is a soft metal that has roughly the same consistency as chewing gum.

When they are working together, NASA said that these ultra-sensitive detectors “can capture vast areas of sky in a single shot while still revealing incredibly fine detail, allowing Roman to map the cosmos faster and more precisely than ever before.”

The Experimental Coronagraph

Astronomers typically infer the existence of exoplanets by the gravitational effects they exert on their host star or the dimming of the star’s light. However, directly imaging exoplanets has remained challenging because the star’s extremely bright light dwarfs the much dimmer light reflected by the planet. As a result, only a few of the largest, young “super Jupiters” have been directly imaged to date.

To block enough of a star’s light to capture an image of an exoplanet, Roman’s engineers have installed a novel Coronagraph. NASA describes this experimental device as “a system of optics, masks, self-flexing mirrors, and sensors designed to demonstrate the most advanced technologies ever flown in space for directly imaging planets around other stars.”

After its mid-flight deployment, Roman’s Coronagraph team will begin conducting a series of pre-planned observations. Mission planners said these observations “are scheduled for a total of three months spread across the mission’s first year-and-a-half of operations.”

 

“The Coronagraph aims to photograph worlds and dusty disks around nearby stars in visible light to help us see giant worlds that are older, colder, and in closer orbits than the hot, young super-Jupiters direct imaging has mainly revealed so far,” the space agency explained.

The Roman team expects to release new images by early 2027. For detailed updates, follow the

Casimir Inc., a technology startup that made headlines with its controversial vacuum energy chip, MicroSparc, has received a financial award from the United States Air Force Research Lab’s SpaceWERX to advance the technology toward practical defense applications.

According to a company statement, the Phase I award, part of the Department of the Air Force’s (DAF) broader Small Business Technology Transfer (STTR) program, will fund Casimir to explore the technical viability of its vacuum energy chip, which The Debrief previously revealed exclusively.

Although a Phase I award does not guarantee future financial support, the new ‘proof-of-concept and potential’ award could put Casimir in line for future Phase II and Phase III awards from SpaceWERX, depending on the success of this phase.

The company told The Debrief that Casimir’s goal “remains full commercialization of MicroSparc by 2028.”

SpaceWERX Award Will Assess Feasibility of Casimir’s MicroSparc Technology

According to the SpaceWERX site, STTR Phase I grants are awarded to companies to “prove the technical merit and commercial viability of your innovative idea.”

“SpaceWERX manages the United States Space Force’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, awarding contracts to startups and small businesses developing technologies with commercial and defense applications that strengthen the U.S. defense industrial base since 2019,” the SpaceWERX site explained.

 

Although Casimir did not provide financial or timeline specifics, SpaceWERX guidelines indicate these awards typically range from $75K to $180K and last three to 12 months. As an “Open Topic” award, Casimir’s work will also include what the SpaceWERX site describes as “a critical customer discovery phase.”

The company said the new award will allow the team to focus on “developing Casimir’s fully independent solid-state generator to address the most pressing challenges in the Department of the Air Force (DAF).”

“The Phase I work is focused on validating Casimir’s independent solid-state generator design against DAF requirements for systems operating in remote or hard-to-service environments,” a company spokesperson told The Debrief. “This is especially notable because it expresses a desire and need for Casimir’s tech in mission-critical environments.”

“The Underlying Physics” Are Not New

Former NASA Eagleworks researcher and Casimir co-founder Dr. Harold G. “Sonny” White later pursued research involving engineered Casimir cavities at the Limitless Space Institute, including work supported by the Defense Advanced Research Projects Agency (DARPA).

“This concept became a central part of our DARPA Defense Sciences Office (DSO) research effort at the Limitless Space Institute, where DARPA funded early theoretical and experimental investigations into custom Casimir cavity structures and their interaction with the quantum vacuum,” White previously told The Debrief.

Although the company previously said it already has functioning prototypes, many scientists have challenged the technology’s validity, with some labeling the MicroSparc a “perpetual motion” machine that violates the laws of physics. When describing the concept to The Debrief, Dr. White seemed to anticipate those criticisms, noting that MicroSparc takes advantage of established quantum physics principles, clarifying that the technology does not violate basic physics principles.

“The underlying physics itself is not new,” White told The Debrief.

Instead, the former NASA scientist noted that the Casimir effect “has been part of established quantum mechanics since the mid-20th century and has been experimentally verified by laboratories around the world.” MicroSparc, he explained, is based on that science.

MicroSparc, White argues, builds on that established physics, although the company’s much more consequential claim—that its device can produce continuous usable electrical power from the quantum vacuum—has not been independently demonstrated.

“In our device, the quantum vacuum outside the cavity walls vigorously stimulates electrons in the wall atoms,” Dr. White previously told The Debrief. “Occasionally, an electron will quantum tunnel from the wall to one of the central pillars.”

For clarification, quantum tunneling is a well-established quantum phenomenon in which a particle has a finite probability of crossing an energy barrier that it could not overcome according to classical physics. The effect has been repeatedly demonstrated experimentally and underlies technologies ranging from scanning tunneling microscopes to semiconductor devices.

“Once inside the protected cavity, the environment is far quieter, (so) the probability of the electron tunneling back to the wall is orders of magnitude lower,” White told The Debrief.

White said this phenomenon creates a one-way flow of electrons toward the pillars, a process he compared to “a kind of quantum ratchet.” By fabricating millions of these microscopic cavities on a single chip, White said his team was able to produce “a continuous electrical current drawn from the quantum vacuum.”

Refining the Vacuum Energy Concept for a Fully Independent Generator

When discussing the significance of the award, especially given the controversial nature of vacuum energy concepts, the company told The Debrief that the award is “a signal to the market and community that this tech is pivotal and up-and-coming…now with gov’t resources.”

Dr. White agreed, noting that “This Phase I award is an important step in exploring how Casimir’s solid-state power technology could support national security missions where persistent, reliable power is essential.”

“As a producer of quantum energy technology, this project will allow the Casimir team to refine the concept for a fully independent generator while working with potential customers to better understand the requirements of systems operating in austere and difficult-to-service environments.”

Moving forward, the company told The Debrief that its goal remains targeting commercial availability of Casimir’s MicroSparc chip by 2028, “positioning the company to disrupt the ultra-low-power electronics sector.”

“The DAF began offering the Open Topic SBIR/STTR program in 2018, which expanded the range of innovations the DAF funded, and now, in August 2026, Casimir will continue its journey to create and provide innovative capabilities that will strengthen the national defense of the United States of America,” the company’s statement explained.

“Much of modern electronics is constrained by batteries, charging cycles, wiring, maintenance, or environmental limitations,” Dr. White told The Debrief. “If this technology scales successfully, its long-term implications could extend from ultra-low-power sensors and consumer electronics to remote infrastructure, defense systems, and eventually space applications, where persistent power is especially valuable.”

Although Phase I STTR awards are a necessary step toward larger Phase II and Phase III awards, which are designed to take emerging technologies proven in Phase I to the market, the company told The Debrief, “it’s way too soon” to realistically think about those steps, while acknowledging the possibility “down the line.”

Details on the technology are available on Casimir’s Website.

After several years of preparation, the Nancy Grace Roman Space Telescope is about to launch.

Here’s a look at the steps, tests, and deployments that NASA’s mission planners hope happen in the hours, days, and weeks after launch.

Nancy Grace Roman Space Telescope’s Carefully Orchestrated Series of Deployments

According to the mission site, once Roman has left Earth’s atmosphere, it will spend the next 90 days going through “a carefully orchestrated series of deployments, calibrations, and tests.”

Within the first hours of launch, NASA says the rocket boosters and main stage of the 18,000-pound (8,000-kilogram) dry-mass spacecraft, which is “about the mass of a Tyrannosaurus rex,” will separate. Soon thereafter, the rocket’s reusable side boosters will return to the area around the launch site and attempt to land.

In space, the rocket’s second stage will separate from the nose cone, which is jettisoned into space. This is followed by Roman separating from the launch vehicle.

To generate power and protect the spacecraft’s sensitive payload, Roman’s solar panels and sunshade will be deployed. According to NASA’s mission fact sheet, each of the space telescope’s six solar panels measures about 7 by 10 feet (2 by 3 meters) and is covered in a total of 3,902 solar cells.

When fully deployed, the panels will combine to provide up to 4 kilowatts of power. For comparison, the mission site says that it is “about the same rate that a modest rooftop solar panel system produces during the daytime.”

The Next 30 Days

Roman will spend the next 30 days speeding toward its final destination, a relatively stable location in the solar system called Lagrange 2, located roughly 930,000 to 1 million miles (1.5 to 1.6 million kilometers) from Earth.

During that journey, the craft’s antenna and deployable aperture will deploy. NASA says the carbon composite radio dish is 5.6 feet (1.7 meters) in diameter. For comparison, the space organization compared its height to an average refrigerator but noted it “weighs only 24 pounds (10.9 kilograms).”

“Its large size will help Roman send radio signals across a million miles of intervening space to Earth,” NASA explained.

One band of the dual-band antenna will receive commands from mission control and return information about the spacecraft’s location and overall health. The second band will communicate what NASA termed “a deluge of data at up to 500 megabits per second.”

About halfway through its voyage, Roman will make a course correction. During that same phase, the spacecraft’s Coronograph instrument will power up. The telescope’s other primary sensor, the Wide Field Instrument, will activate a few weeks later.

“With all components fully deployed, NASA said Roman is over 42 feet (12.7 meters long) and over 14 feet (4.4 meters) wide. The space agency said these dimensions make Roman “about the size of a tour bus.”

Finally, NASA said that throughout the rest of its 90-day commissioning period, both the antenna and Coronagraph “will run through a series of calibrations and tests.”

First Images Expected in 2027

Although the agency did not specify an exact date for the space telescope’s first light, the Roman team said it “anticipates releasing new images by early 2027.” For detailed updates, you can also follow NASA’s official Roman blog.

A spacecraft propelled by a subluminal warp drive would cause an extremely bright glow if it passed through Earth’s atmosphere, according to findings detailed in a new study.

Physicist Shaun Fell from the international think tank Applied Physics (AP) and Harvard astrophysicist Avi Loeb detail their findings in a new paper, which also suggests that extremely small “warp bubbles” could be used as weapons, and that Einstein’s theory of general relativity permits warp bubbles with micrometer-sized surfaces housing very large craft, similar to technologies that appear in science fiction.

The authors emphasize that their new study, which appeared on the preprint server arXiv and has not yet been peer-reviewed, does not prove the existence of aliens, extraterrestrial technology, or warp drives. However, they suggested their analysis offers a viable scientific foundation for many UAP reports of bright lights and “orbs” discussed in recent Pentagon file drops, and is supported by a mathematically valid means of interstellar travel that interplanetary visitors—if they exist—might use to reach Earth.

“Warp drives are a fantastic way to travel through the universe, and it makes sense to my human brain that aliens would find them advantageous too,” Dr. Fell told The Debrief.

Warp Drives: From Science Fiction to Science Fact?

Science fiction authors have proposed ways to travel faster than the speed of light for decades. In the 1960’s, science fiction TV trendsetter Star Trek brought the concept to the wider public with the U.S.S. Enterprise’s infamous Warp Drive. Although a convenient storytelling tool for propelling the show’s heroes across the cosmos at human time scales, the scientific viability of warp drive travel didn’t exist when creator Gene Roddenberry’s vision first premiered.

In 1994, Mexican mathematician Miguel Alcubierre moved the discussion from science fiction to science fact when he proposed the first mathematically viable warp drive metric. Since then, several other scientists have weighed in, including noted NASA warp drive pioneer Harold G. Sonny White. Still, even the most elegant mathematical solutions for traveling faster than the speed of light have hit roadblocks that prevent their realization, including the use of exotic forms of matter that exist only in theory.

In an email to The Debrief, Dr. Fell explained that superluminal warp drives (meaning faster than light) “have a whole host of fundamental difficulties that have not been solved yet, not even including negative energies that have historically plagued previous solutions.”

The Debrief previously covered the Applied Physics team’s attempt to solve the problem with a physical warp drive capable of approaching the speed of light but not exceeding it. Although that metric has conquered outstanding physics hurdles that have hampered previous models, the AP team said their new paper used a subluminal version of the original Alcubierre metric.

“The Alcubierre metric is used as a proxy for any zero ADM mass solution, meaning any warp drive solution that does not exhibit typical gravitational effects,” Dr. Fell explained.

Any Warp Bubble Traveling Faster than 5% the Speed of Light

In a recent post on Medium, Dr. Loeb said his previous studies confirmed that the distortion of spacetime proposed in the warp drive metric “must perturb the air” when passing through Earth’s atmosphere. The Harvard scientists also noted that those studies showed that such an atmospheric perturbation caused by a relativistic warp drive “would inevitably generate a bright fireball by shocking the air around it.”

In a previous article, AP physicists told The Debrief that a well-known 2006 UAP sighting in Chicago that included a hole “punched in the clouds” also fits with predictions of warp drive interactions with Earth’s atmosphere.

To follow up on his latest proposal, Loeb and Fell conducted detailed hydrodynamical simulations of the airflow around warp bubbles encasing theoretical spacecraft. In warp drive models, a warp bubble encases the craft in an area of stable space, keeping it completely still as the drive propels toward its destination by warping space itself. This effect is what gives the drive its name.

After running the numbers, Loeb and Fell determined that the heated air around the warp bubble would reach 220 billion degrees Kelvin if the spacecraft was traveling fast enough. Critically, the team calculated the effects of such craft passing through the atmosphere “at a fraction of the speed of light.”

“Any warp bubble traveling faster than 5% the speed of light through the atmosphere will generate optical signatures qualitatively the same as those presented in our paper,” Fell told The Debrief, before adding “slower than that, and the optical signature has a different physical origin.”

Loeb said the calculation suggests that an “aircraft-scale” spacetime (warp) bubble moving at the right velocities would produce luminosities exceeding one terawatt. For comparison, the AP scientist noted that this amount of energy is roughly one-tenth of global electric power consumption.

A “Brilliant Fireball” Detectable at Great Distances

When describing how this high-energy atmospheric interaction would appear to a ground observer, Loeb said, “It should be easy to detect such a brilliant fireball at great distances.”

For example, Loeb explained that any observer would witness two distinct signals suggesting that a warp drive-propelled craft has entered the atmosphere. The first would be a direct, high-energy burst of radiation emanating from the shock zone. Next, a wave of extremely energetic photons would get absorbed by the thicker lower atmosphere. Loeb said this “extreme” energy ends up “reradiated” as light in the visible ultraviolet (UV) spectrum.

“This will manifest itself as a bright atmospheric glow directly below the shock zone,” the Harvard scientist explained.

The study authors also noted that some fireballs would be larger than others. In the right scenario, Loeb suggested that the atmospheric glow caused by a warp drive could “completely dominate the surface solar flux by orders of magnitude.” This means it would be the brightest object in the sky even during daytime.

Conversely, the Applied Physics team noted that warp drives moving much more slowly through the atmosphere, including just above the speed of sound, would not be nearly as bright as those moving above 5% the speed of light. Loeb said warp drive craft at rest or moving well below relativistic speeds “would not generate such extreme luminosities.”

Micrometer-Sized Warp Bubbles as Weapons?

Another intriguing aspect of the study involves the possibility of extremely small warp bubbles interacting with the atmosphere to generate visible light signatures. For example, Loeb suggested that “a micrometer-scale bubble moving at a few times the sound speed at sea-level would result in a modest luminosity of order 1 kilowatt.”

“This slower velocity regime is something we are currently studying,” Fell told The Debrief.

When asked what practical benefits a micrometer-sized warp bubble seemingly too small to accommodate a full-sized spacecraft might offer, Fell joked that a discussion with “my alien buddies” resulted in some unexpected solutions. This included one potentially ominous possibility and another more fantastical explanation that sounds like something right out of the world of Harry Potter.

The first harrowing solution Fell and his hypothetical “otherworldly” colleagues offered involved using tiny warp drive-enabled craft as weapons. For example, the AP physicist explained, even a microscopic warp bubble would exhibit “tremendous gravitational tidal forces.” Based on their models, Fell told The Debrief that such a micrometer-sized warp bubble “would obliterate almost any material in its path, especially if it’s traveling exceedingly fast.”

“This is a very difficult topic to analyze critically because we don’t really know if superluminal warp travel is allowed by the laws of physics,” Fell also told The Debrief. “Would it create observable signatures? Almost certainly. Would any human still be alive to record the measurement? Probably not.”

The Interior of a Tiny Warp Bubble—Harry Potter’s “Weasley Tent”?

Since any plan that would likely annihilate the Earth “wouldn’t be very practical for the aliens,” Fell offered The Debrief an even more fantastical explanation for why our spacefaring visitors may want to engage a micrometer-sized warp bubble, which scientists call the Van Den Broeck warp drive.

As Fell explained, general relativity allows the surface area of a theoretical warp bubble to be microscopically small, “while the interior volume may be as large as you want.”

“I always think of the Weasley tent at the Quidditch World Cup in the 4th Harry Potter book (Harry Potter and the Goblet of Fire),” the AP physicist told The Debrief. “The outside looks like a normal camping tent, but the inside is this great big room.”

Surprisingly, such fantasy world solutions to practical scientific problems are theoretically achievable within general relativity. As a result, Fell added, if the models were correct and such a warp bubble was viable, relativity as we understand it “provides an avenue for microscopic warp bubbles that can house great big ships or other cargo.”

“The applications are really endless for that,” he added.

Connecting Warp Drive Physics with UAP Sightings

When discussing the connection between their findings and the accounts of Unidentified Aerial Phenomena (UAP) chronicled in recent Pentagon document releases, Loeb pointed to a series of ‘puzzling’ orbs “mentioned explicitly in a reliable report dated June 5, 2026.”

According to Loeb, that report, signed by Dr. Jon Kosloski, director of the All-Domain Anomaly Resolution Office (AARO) in the Pentagon, describes “an orange ‘mother’ orb launching smaller red orbs.” Loeb’s retelling of Dr. Kosloski’s account also notes that “40% of the phenomena during the reported event lack a reasonable explanation and remain unresolved.”

Although some UAP reports describe physical craft, researchers have often noted that the largest category involves glowing light or orbs. Although Loeb did not suggest all or any sightings were alien craft, the study’s author noted that warp-drive physics supports the idea that some of these reports could be explained by advanced propulsion technology.

“Could some of the reported orbs be slow warp bubbles?” Loeb asked. “There is one way to find out: by studying them experimentally.”

Dr. Fell agreed, telling The Debrief that “the important thing is that purported UAP observations can be critically examined through the laws of physics, as we know them today.”

“If there really are intelligent beings visiting our Earth, how did they get here?” he asked. “What was their mode of transport? If such a spacefaring vehicle entered our atmosphere, what would it look like?”

While neither author suggested that their mathematical solution settles the debate about aliens or alien craft visiting Earth, Fell said their paper “places observational constraints on these questions and narrows the possibilities.”

AP founder Gianni Martire similarly told The Debrief that his team’s paper does not prove warp drive or alien life. However, the enthusiastic scientist did note that the mathematics makes it possible that science “may simply be catching up to UFO lore that has existed for hundreds of years.”

“It’s possible E.T has been flashing his headlights at us along, not by choice,” Martire said.

The study “Radiative Signatures from Warp Drives Traveling Through the Earth’s Atmosphere” is available on the preprint server, arXiv.

A University of West Bohemia (UWB)- led team of archaeologists has unearthed an ancient Czech ritual center linked to the movement of the Sun and Moon, predating Stonehenge by over 1,000 years.

The UWB-led team behind the discovery said the site’s 6,500-year-old age makes it one of the oldest monuments of Central Europe. Moving forward, the researchers plan to take soil samples from the enclosure and its surroundings to examine chemical traces left by the site’s ancient inhabitants.

Ancient Ritual Center Predating Stonehenge Tracks Sun and Moon Positions

According to a UWB statement, the newly discovered almost circular enclosure was found at present-day Chelby. Initial measurements set its diameter at 230 meters. The ritual center also featured a 2.5-meter-plus ditch and twelve entrances placed at irregular intervals.

Research team leader Petr Krištuf of UWB’s Department of Archaeology at the Faculty of Arts said circular enclosures like the Chelby structure are completely unknown in this region, making the site “exceptional.” However, Krištuf explained, when researchers began analyzing the positions of the asymmetrical entrances, “it became clear that their arrangement was not random.”

“Their geometry creates a system that made it possible to observe the most significant moments of the solar and lunar cycles,” the UWB researcher explained.

A more detailed survey of the newly discovered ritual center revealed two main observation points designed for specially timed observations of the Sun and Moon. The researchers said the first appears to be “associated with the Moon’s extreme positions on the horizon during its approximately 18-year cycle.”

The team said the second observation point identified during the survey connects the sunrise at the summer solstice, the longest day of the year, with sunset on the winter solstice, the shortest day.

Archaeologists Note Site’s Similar Astronomical Alignments to Famous Neighbor

Although the site is not the only ancient monumental structure in the region, the team used organic material to date the newly discovered enclosure to 6,500 years before present. For comparison, the relatively nearby Stonehenge monument, which also contains astronomical alignments connected to the Sun and Moon, was built over 1,000 years later.

Krištuf said the astronomical alignments found at the Chelby site are not unusual for prehistoric people. The researchers specifically highlighted the symbolic nature of sunrise and the summer solstice marking a beginning for prehistoric farming communities known to inhabit the region. They also noted the winter solstice “represented an ending” for these same ancient farmers.

“The same principle can be seen along Stonehenge’s main axis,” the researcher explained. “We can now see that the sanctuary at Chleby was designed similarly. Still, more than a thousand years earlier, as we have established from the dating of organic material.”

Additional evidence found at the site also suggests the newly discovered enclosure was a ritual center where people performed ceremonies celebrating astronomical events. For example, the team unearthed bull skulls and horns in the ditches near the entrances.

Archaeologist Jan Turek, who is involved in the research on behalf of Charles University, said the artifacts, which are similar to objects excavated near Stonehenge, suggest the ritual center’s ancient builders may have decorated the monumental gateways leading into the enclosure.

“The cult of the bull was an important religious symbol among the first farming communities and is known from many parts of prehistoric Europe,” Turek explained. 

Krištuf said their research also unearthed several iterations of the ritual center. The team leader said this feature sets it apart from its nearby, more well-known successor.

“While Stonehenge experienced repeated periods of renewed use and is still associated, for example, with Celtic druids, the first results from Chleby suggest the opposite development,” he explained. “By the Iron Age, the monument appears to have definitively lost its original significance. The ditch was gradually filled in, and an ordinary settlement was established on the site of the former sanctuary.”

Upcoming Soil Samples Could Fill in Missing Historical Blanks

The next step in the ancient ritual center’s excavation will include a detailed soil analysis. Jan Fišer of the University of Hradec Králové, who is analyzing soil samples from the enclosure and the immediate surrounding area, noted that chemical traces in the soil can complement artifacts and human remains.

“These can help us understand how this exceptional site was used during different periods of prehistory,” Fišer explained.

The new excavations and upcoming soil analysis are part of a greater international effort, Long-term Land Use Dynamics within the Areas of Prehistoric Ritual Places. That project focuses on changes in prehistoric ritual landscapes like Stonehenge and the new Chelby site.
