An ethereal and magnificent display of gas and dust stretches across the cosmos in a spectacular new image captured by NASA's James Webb Space Telescope.

What is it?

Glowing wisps of translucent gas and dust paint a striking image of the star-forming region IC 348 in this new JWST snapshot. In the image, you can see IC 348, a region found about 1,000 light-years away.

In this vast expanse of gas and dust, cold molecular hydrogen gas collapses to create new stars. And this image has no shortage of suns, with twinkling stars speckling the entire cosmic landscape, diffraction spikes and all.

But while this is a star-forming region, objects are found here as well. This image was captured as part of a scientific search for brown dwarfs, which are objects that form like stars but aren't massive enough to kickstart hydrogen fusion in their cores.

Why is it incredible?

Brown dwarfs are one of the great mysteries of our universe. Not as massive as the least massive stars, but more massive than the biggest planets, brown dwarfs are strange objects stuck in the middle.

Brown dwarfs do emit some light and heat, which helps scientists to find them, though doing so can be tricky, as they're much cooler than stars and not that bright (at least in visible light). However, despite being dim, they give off infrared radiation, allowing them to be spotted by infrared instruments aboard space telescopes like JWST.

This incredible new image is part of an observing program that aims to use JWST to find and study the smallest brown dwarfs. In 2022, researchers looking at IC 348 found brown dwarfs just a few times more massive than Jupiter, so they were on the very small end. Researchers hope to find even smaller brown dwarfs to help them better understand how these strange objects form and vary across space.

Is that a footprint on Mars? Sorry to burst your bubble, but no. However, scientists have found a strange feature unlike anything they've seen before on the Red Planet's surface.

What is it?

While NASA's Perseverance rover is the newest addition to the agency's robotic Red Planet fleet, its cousin Curiosity is still going strong and finding strange and unusual things on Mars 14 years after landing.

In new observations captured on Mars' Mount Sharp, the Curiosity team has identified "features unlike quite anything we have seen in the past," Michelle Minitti, deputy principal investigator for Curiosity's Mars Hand Lens Imager (MAHLI), said in a statement.

These mysterious features are a bunch of broad, shallow pits scattered across the Martian bedrock.

Why is it incredible?

While little pits and divots are common to find on the Martian surface, these wide, shallow pits that researchers saw with Curiosity are quite different from surface features that have been seen before.

"The pits of this week were much broader and shallower than past features and were not accompanied by obvious objects that were once in the pits," Minitti said.

The team collected as much data as they could on the strange pits using Curiosity's various instruments, including MAHLI, the Mastcam camera, ChemCam (the Chemistry and Camera complex) and APX (Alpha Particle X-Ray Spectrometer).

They have so far found interesting layers in the pit material that seems chemically different from the main bedrock.

But we will have to wait and see what else researchers might be able to learn about these odd pits. How did they form? How long have they existed? What can they tell us about the history of Mars?

If this summer felt hotter than usual, you're not alone. As it turns out, this past summer was the hottest on record in the United States.

This is the hottest that summer in the U.S. has been in at least 132 years. Specifically, the temperatures rose to 3 degrees Fahrenheit (1.67 degrees Celsius) above average, beating out the most recent record set in 2021 of 0.4 degrees F (0.22 degrees C) above average, according to a new report from National Oceanic and Atmospheric Administration (NOAA). And looking month-to-month, this was also the hottest August we've ever seen.

The record-breaking season saw unmatched temperature highs across the contiguous U.S. (all of the adjoining states, excluding Alaska and Hawaii which just aren't a part of this record) from June through August. But scorching temperatures aren't all that this new record reveals, as this summer was also one of the driest on record for the contiguous U.S., with more than half of the country in a drought by September. The summer of 2026 saw both extreme precipitation highs and lows across the country, too. From droughts to heavy rain, there was nothing average about the precipitation seen across the U.S. this summer.

A closer look

Digging into some of the details, the full summer was 3 degrees F above the average for the season, 74.4 degrees F (23.5 degrees C). August was 3.5 degrees F (1.94 degrees C) above average for the month at 75.6 F (24.2 C). And while most of the contiguous U.S. experienced well above average temperatures this summer, some locations felt the heat the most. The Southwest, the southern Rockies, the southwestern Plains, southern Florida, California, Nevada, New Mexico and Colorado hit particularly high temperatures this August.

Looking at the summer's unusual precipitation levels, the total precipitation across the contiguous U.S. was 0.32 inches (0.8 centimeters) below average, making this past summer the third driest on record, and the driest summer since 2000. By Sept. 1, 59.1% of the country was in drought. There was drought across the West, the upper Midwest, the Deep South and more. Over 75% of Puerto Rico lie in drought conditions as well, with 40% being in "extreme drought." And while summer might be ending, a lot of this drought is projected to continue, according to the report from NOAA. When it comes to drier lands, that also means an increased risk of wildfire.

Though these temperature differences might seem small or relatively mild at face value, they have massive consequences. As climate change progresses primarily due to greenhouse gas emissions caused by human activities like transportation and manufacturing, we continue to see a whole host of its effects across the world. This ranges from rising average temperatures and glacial ice loss to sea level rise and worsening natural disasters. Those natural disasters include events like flooding, hurricanes, wildfires and cyclones.

While different areas of the world will experience different effects of global warming, one thing remains true for all: The consequences will only continue to worsen as our planet warms.

If we just look at this past August 2026 in the U.S., not only did we see record-high temperatures, but also weather and climate disasters of all varieties. Fires broke out over 10,000 acres of eastern Washington, even spreading across the state and into Oregon. More fires, in fact, spread across Nevada and Alaska while wind gusts up to 111 miles per hour (178.6 kilometers per hour) tore across South Dakota. A heatwave brought sweltering temperatures to south Florida and Hurricane Lala brought intense winds, rain and flooding to Hawaii;. And these are just a few of the many examples — from just this last month.

Everyone needs a helping hand from their friends now and again  — even space stations. Recently, the International Space Station got an orbital boost from the docked Cygnus XL spacecraft, helping the station get to the correct altitude.

What is it?

On Aug. 27, while attached to the International Space Station's Unity module, Northrop Grumman's Cygnus XL cargo spacecraft turned its engines on and fired them.

This planned maneuver lifted the space station's orbit, pushing it into a higher altitude. This image snapped from orbit shows Cygnus, named for the swan constellation, as it's attached to the station for this planned push.

But why lift the space station to a higher altitude above Earth?

Next week, the space station will receive a new visitor: the Progress 96 resupply spacecraft. This altitude shift allowed the space station to shift into a position that will allow Progress 96, the 96th cargo mission in a series of Russian Progress cargo missions, to rendezvous and dock with the station.

Why is it incredible?

This maneuver was routine, but emblematic of the incredible progress we've made in space. Not only can we build spacecraft and send them into orbit, but we can control these spacecraft well enough that they help each other out, boosting each other when necessary.

And while Progress 96 might seem like a run-of-the-mill cargo ship carrying cargo like water, fuel, food, scientific instruments and additional supplies to the station, it is also the 96th Progress mission to a space station. In fact, the first Progress mission took place way before the International Space Station even existed. This first mission sent cargo to the Soviet Salyut 6 station all the way back in 1978 and with 96 on the verge of liftoff, the Russian Progress missions are going strong to this day.

Together, the combination of this lift maneuver and this 96th cargo mission show how incredibly well we as humans have worked together to build a sustainable presence in orbit and how that has happened with the aid of international collaboration between nations like the U.S. and Russia.

Are those purple, wavy, alien thumbprints? Or perhaps an otherworldly ocean? Nope! It's actually a dune field on Mars, colored purple.

What is it?

Across the Martian surface are all sorts of unique features in the rocky, dusty surface material. In this false-color image, snapped by the HiRISE (High Resolution Imaging Science Experiment) camera on NASA's Mars Reconnaissance Orbiter, you can see the incredible and strange ripples of a dune field on Mars.

"Our science goal for this observation is to observe any changes from a previous image we acquired in 2011," a statement sharing the image reads. "For this footprint, the target enlarged and centered more over the dune field, which is located on the floor in the northern half of an unnamed impact crater."

Why is it incredible?

Spacecraft like MRO, with its HiRISE camera, have opened our eyes to the incredible features across the Martian surface.

From dune fields like we see here to craters and ancient riverbeds, these views have helped scientists piece together the planet's incredible, dynamic history. For decades, observations from orbit around Mars and by rovers on the planet's surface have helped to solve at least part of the mystery of what Mars was once like.

Researchers are still looking for signs that unequivocally point to life once existing on the planet. But so far, observations have showed that, billions of years in the past, Mars had abundant surface water — lakes, rivers perhaps even a huge ocean. In analyzing the material in and near ancient waterways on the planet with NASA's Perseverance rover, researchers have already found evidence that could possibly link to biosignatures.

While this image might look like a strange but beautiful purple-colored desktop background, photos like it this can be essential clues for scientists hunting for answers.

Decades ago, Captain Kirk faced off against the Gorn on the uncharted desert planet Metron. But as we can see in new satellite imagery from NASA, that mysterious rocky world can actually be found right here on Earth in California.

What is it?

In this new image captured by the Operational Land Imager (OLI) on NASA's Landsat 9 satellite, you can see the wide variety of rock and vegetation in the area around Vasquez Rocks Natural Area County Park in southern California.

The 25-million-year-old Vasquez Rocks is a magnificent natural area with an incredible range of unique, large rocks jutting out of the ground. In this false-color image, you can see the area in shortwave-infrared and near-infrared wavelengths that show the differences in vegetation across the landscape.

And this location hides some amazing history. Not only is Vasquez Rocks home to incredible rock formations and desert vegetation, it is also where Captain Kirk fought the Gorn in Star Trek the Original Series. It's not a surprise the series chose this location for its infamous fight scene (among many other Trek scenes), as the massive, sun-bleached boulders pointing to the sky and barren landscape give it a distinctly alien feel.

Why is it incredible?

While the rocky landscape of Vasquez Rocks is firmly fixed here on Earth, it has consistently made history as the backdrop to a whole host of iconic science fiction moments.

Indeed, Star Trek is one as Vasquez Rocks has been used for filming in a whole host of Trek episodes. It was even Spock's home world of Vulcan in the films Star Trek IV: The Voyage Home and Star Trek (2009).

But beyond Star Trek, the site has been used for filming sci-fi classics like Galaxy Quest, Battlestar Galactica and Planet of the Apes in addition to a whole host of cowboy movies and more.

It turns out that right here on Earth, we can find perfectly good alien worlds.

Global warming will soon cross a critical threshold, surpassing a dangerous limit set years ago, the United Nations Environment Programme (UNEP) has found. But experts say it's still possible to cool things back down, emphasizing that the stakes are too high to stop trying.

In 2015, 196 nations and territories signed the Paris Agreement, pledging to restrict the average rise of global temperatures to below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels. Ideally, the rise was meant to be kept to 1.5 degrees C (2.7 degrees F) above those levels. However, according to a new report detailed by the UNEP, we are on track to cross that 1.5 C line — and soon.

"This summer's scorching heat, raging wildfires and deadly floods are a warning of what lies ahead. We must make the overshoot above 1.5 degrees as small and short as possible. That demands an overshoot of ambition," U.N. Secretary-General Antőnio Guterres said in a statement.

According to the new report, experts have found that if we as a planet continue with business as usual, not only will we pass 1.5 C, but it will happen within just a few years. The report, however, maintained a positive tone. Rather than simply predicting a doomsday plot, the main purpose of this release is to outline a pathway with the necessary steps to set things on the right track.

"As global temperature rise gets set to cross 1.5°C, pushing climate risks and impacts to dangerous new heights, the world must strive to return to below 1.5°C as soon as possible and simultaneously reduce the vulnerability of societies, communities and economies to climate impacts," the report, titled "Limiting Overshoot: Navigating exceedance of 1.5°C and pathways towards return," states in its abstract.

Climate change is primarily caused and driven by human activities like transportation, industrial manufacturing, agriculture and more. According to the report, the two main aspects of this work need to be: reducing emissions and enabling adaptations to protect people impacted by the effects of climate change.

The U.N. states in the report the necessity of both an immediate and sustained reduction in the emissions of greenhouse gases like methane and carbon dioxide. Not only do we need to find a way to cut emissions fairly immediately, but we also need to find a way to sustain that effort over time. The U.N. further states it is important to not only work toward removing carbon from the atmosphere, eventually reaching net-negative emissions where more emissions are removed by humans from the atmosphere than added to the atmosphere.

This sort of carbon capture technology is still fairly early in its development, but according to the U.N., it is essential we find ways to rapidly move toward a future where we can capture and store carbon from the air and therefore reduce the quantity of greenhouse gases around our planet.

In addition to these long-term emission reduction actions, in this report the U.N. has also asserted that this process will need to include "adaptation actions," or ways to support the many people and communities already affected by climate change.

Even if all of the world's nations start working immediately to drastically reduce emissions, we are already seeing the sometimes fatal and irreversible effects of climate change. From increasing the intensity of wildfire seasons to worsening natural disasters, climate change is far from a distant future. It's our reality, especially for those living in high-risk areas like coastlines. So, while the nations of the world need to work together to reduce emissions, it is also important that adaptations are found to reduce the existing and future impacts of climate change on our communities.

"There are no good outcomes if we remain above 1.5°C. Across the globe, extreme heatwaves are already proving that climate impacts will strike faster, hit harder, and last longer — costing more lives and causing deeper disruption," Inger Andersen, the Executive Director of UNEP, said in the same statement. "Now is the time we must double down on climate action. We can — and must — get on the right path. By cutting greenhouse gas emissions, strengthening resilience and adaptation, and ensuring exceedance of 1.5°C is as small and short as possible."

A volcano on an Indonesian archipelago began erupting on Sept. 4, and satellites in orbit have been watching closely.

What is it?

The volcano Anak Krakatau started spitting out ash and lava on Sept. 4. On an archipelago between Sumatra and Java, the island volcano's sudden eruption grounded flights, closed schools and even stopped fishing in the area.

The volcano launched ash into the air and into the city of Jakarta and the Lampung province during a 25-hour-long eruption. But even following this eruption, Anak Krakatau remained active throughout the weekend. In fact, the volcano is still so active that it could erupt again soon.

But it wasn't just people on Earth watching the volcano erupt this past weekend. The Landsat 8 satellite, operated by NASA and the U.S. Geological Survey (USGS), spotted a white plume of volcanic gas billowing into the atmosphere all the way from space. The white plumes of gas are thought to mainly contain water vapor, carbon dioxide and sulfur dioxide, while ash and debris make up the brown clouds surrounding the plumes.

Why is it incredible?

While Anak Krakatau simmers after this most recent eruption, this event isn't a major shock, as the volcano sits in what is known as the "Ring of Fire." This "ring" (a loose term, as it's not exactly a ring) snakes about 25,000 miles (40,000 kilometers) around the Pacific Ocean and includes over 750 volcanoes, some dormant and some active.

In fact, in Indonesia alone there are 500 volcanoes, and 127 of them are active, including Anak Krakatau. And this volcano has a particularly interesting story: It emerged from the sea in 1927, rising from the caldera formed by the 1883 eruption of Krakatau (also known as Krakotoa), which was one of the most famous and destructive volcanic events in history. (Anak Krakatau means "child of Krakatau" in the Indonesian language.)

While not all geologists agree on the exact margins of the Ring of Fire, it rests on a string of tectonic plates and has existed for over 35 million years. And not only is this ring home to hundreds of volcanoes, it's also a hot spot for earthquakes.

Scientists have captured the sharpest image ever of our sun's surface. This view has revealed incredible new details about the inner mechanisms driving stellar activity.

What is it?

An international team of researchers using the U.S. National Science Foundation's Inouye Solar Telescope has captured the highest-resolution view of the sun's surface.

In analyzing observations from this telescope, the team, made up of researchers from the National Solar Observatory, the NSF NCR High Altitude Observatory and the German Max Planck Institut für Sonnensystemforschung, discovered strange patterns on the sun's surface. The whirling patterns, they found, are actually evidence of what's called Kelvin-Helmholtz instability (KHI), or instability that happens when there is a change in velocity of fluids.

Why is it incredible?

This image is groundbreaking. Capturing the highest-resolution view of the sun's surface is a massive accomplishment, and in the time-lapse video above, you can even see the fluid dynamics on the surface of the sun in motion.

But this view is much more than a beautiful, high-resolution image. These observations have revealed swirls on the sun's surface at the edges of the magnetic areas, allowing the team to identify KHI on the sun's surface. This fluid instability has long been suspected on the sun, but these observations are the first time they have ever been directly seen like this.

“We believe that the discovery of Kelvin-Helmholtz Instability in the solar photosphere, backed up by analysis of numerical simulations, is a major step forward in our understanding of the dynamics and evolution of solar and stellar plasma, and will serve as a basis for future discoveries," David Boboltz, the deputy director at the National Solar Observatory, said in a statement.

A paper describing these findings was published recently in the journal Nature.

Picture it: A swarm of tiny robot helicopters descends through a reddish-brown sky, landing gracefully on the Martian surface. What are they wearing? Tiny capes.

NASA's SkyFall mission will send a trio of mini rotorcraft to Mars equipped with ground penetrating radar technology which happens to look like little capes. These uniquely designed swaths of fabric look decidedly strange or even accidental in new videos from NASA's Jet Propulsion Laboratory (JPL) that show the little drones practice landing. But these capes are actually flexible antennae that will allow the craft to peer beneath the Red Planet's surface in search of water ice.

"The only way to detect shallow subsurface ice remotely is to fly close to the ground," Adrian Tang, SkyFall’s ground-penetrating radar lead instrument scientist at JPL, said in a statement on Thursday (Aug. 6). "By flying low and slow, a SkyFall helicopter could capture radar images that resolve the fine layering where dry soil gives way to ice, detecting its presence and mapping its extent."

Orbiting spacecraft have studied Mars for decades, imaging the planet and mapping it with radar. But from orbit, their radar is unable to see the first few feet of material just below the planet's surface — a zone where scientists expect to find shallow ice deposits mixed in with the rocks and dust. This work could be important for future astronauts who need to better understand the ground below their feet for safety reasons, and for future travelers searching for accessible ice to process for drinking water, oxygen and fuel.

Skyfall will follow in the footsteps of Ingenuity, the first rotorcraft on another world, which hitched a ride to Mars aboard NASA's Perseverance rover. The new choppers are based heavily on Ingenuity, which weighed just 4 pounds (1.8 kilograms) here on Earth. But Skyfall will be more capable than Ingenuity, whose main job was to show that choppers can explore the thin skies of Mars.

SkyFall's tiny cape ground-penetrating radar, which uses a type of flexible antenna called Vivaldi that was invented back in 1978, is designed to survey up to 16 feet (5 meters) below the Martian surface. The radar will be able to reach anywhere from several yards below the planet's surface to the uppermost layers of surface material.

And the antenna's unique design ensures that the SkyFall drones will be able to make these subsurface observations without damaging the equipment during landing.. The antenna is extremely lightweight, and the team miniaturized it to be both the right size and shape to fit the tiny helicopters, which sit just 6 inches (15 centimeters) above the ground at rest. The tricky thing was, the designers had to miniaturize the radar antennae while maintaining functionality. But they did just that, and these tiny radar capes will be able to bend and move out of the way as the rotorcraft do their thing, flying above and landing on the Red Planet.

"Although we managed to shrink the antenna quite a bit, it is about 1.5 times longer than the helicopter’s legs," Christine Gebara, SkyFall ground-penetrating radar mechanical lead at JPL, added in the statement.

"That means during landing, the Vivaldi has to bend out of the way — and if it lands on a rock, it bends even further," she added. "But when the helicopter takes off again, the antenna must spring back into place for data collection. Because SkyFall is expected to make dozens of flights exploring Mars, we needed an antenna that could repeatedly handle those pressures without losing its shape in flight."

To make these little capes capable of withstanding incredible feats on another world, the engineers behind the helicopters covered the antenna in layers of polyester and Vectran, a flexible (but incredibly strong) material that was previously used for the airbag that cushioned NASA's Spirit and Opportunity Mars rovers during their touchdowns in 2004. The antenna's shape is also reinforced with flexible fiberglass tape springs and a lightweight structure. In total, each antenna weighs a miniscule 5 ounces (142 grams).

But a crafty design isn't enough. Getting to Mars is no small feat, and NASA needs to be sure that these little helicopters and their gear are up to the challenge. So, in JPL's Environmental Test Laboratory, which recreates different elements of environments beyond Earth, the SkyFall team put the rotorcraft and its little radar antenna to the test. They bent and flexed the antenna over and over, recreating multiple landings on the surface, exposed the craft to extreme temperatures, and continually checked to make sure that, throughout this testing, the helicopter could still transmit and receive radar signals. At the end of this testing, the antenna had endured 200 simulated Mars landings and was still working just fine. That is more than twice the number of landings expected from the mission.

"This test checked every box it was supposed to and answered our biggest technical questions," Tang added. "While we still have work ahead of us before the antenna is fully flight-qualified, this was a major milestone, and the hardware performed exactly as expected."

The trio of SkyFall helicopters will put their radar capes to the ultimate test when they fly to Mars. NASA plans to launch this mission to the Red Planet in 2028 aboard NASA's Space Reactor-1 Freedom, the first nuclear fission-powered interplanetary spacecraft.

In a nebula far, far away, colossal clouds of dust and gas tower amongst the stars.

What is it?

This spectacular new image from the James Webb Space Telescope showcases the brilliant majesty of the Carina Nebula, a giant cloud of dust and gas found 7,500 light-years away in the constellation Carina.

You may have seen the Carina Nebula before — in the first-ever image released from JWST, which has been dubbed "Cosmic Cliffs."

In this new image, captured by JWST's Near-Infrared Camera (NIRCam), you can see the nebula in a whole new light. This snapshot captures a specific feature that is being dubbed the "Treasure Chest," as it vaguely resembles a glowing coffer overflowing with stellar jewels.

This "Treasure Chest" contains a cluster of young stars, approximately 70 stars in total. While these might be young, growing stars, the most massive of the bunch is a whopping 19 times more massive than our sun.

Why is it incredible?

While JWST has looked at the Carina Nebula before, new observations can reveal completely new details and help scientists uncover new information about the nebula and the strange ways in which the universe works.

Right now, scientists think that the star cluster in the "Treasure Chest" is about 1.3 million years old. However, previous estimates thought the grouping could be just 100,000 years old. So, new observations by powerful telescopes like JWST can significantly change our understanding of the cosmos.

With each new observation or data point, the history and context of the universe around us could completely transform. And, as this star cluster grows over time, its stars will become more brilliant. They may therefore illuminate more of this star cluster, potentially revealing details and secrets of this "treasure" that scientists might never have predicted.

Early this morning, a SpaceX rocket slammed into the moon at seven times the speed of sound. Now, lunar orbiters are trying to get a look at the aftermath.

This morning (Aug. 5) at about 2:35 a.m. EDT (0635 GMT), the upper stage of a SpaceX Falcon 9 rocket crashed into the moon. To dissect what exactly happened, scientists are looking for imagery of the crash site, with the help of a couple of moon probes.

"NASA’s Lunar Reconnaissance Orbiter and NASA’s ShadowCam instrument on the Korea Pathfinder Lunar Orbiter will look for opportunities to capture before‑and‑after imagery of the impact site," NASA spokesperson Rob Garner, of NASA's Goddard Space Flight Center in Maryland, told Space.com. "Image availability depends on several factors, including the impact location, lighting conditions, and when each spacecraft’s orbit next carries it over the area, which may take a few days to receive any imagery."

While you've likely seen the first stages of Falcon 9 rockets gracefully land back on Earth for reuse, the rocket's 9,000-pound (4,000 kilograms) upper stage is disposable. Typically, it's sent to burn up in our atmosphere after its missions are over.

However, that wasn't possible with this rocket, which launched two private lunar landers — Firefly Aerospace's Blue Ghost and Tokyo-based ispace's Resilience — to a high, moon-crossing Earth orbit in January 2025. The Falcon 9 upper stage used most of its fuel getting to this distant location and couldn't make it back to deorbit in Earth's atmosphere.

So the company performed a different maneuver to take care of this upper stage, Julianna Scheiman, director of NASA science and Dragon programs at SpaceX, said during a press conference on Aug. 3.

"For high-energy missions, we need to perform a different maneuver to ensure the second stage itself is safe per the appropriate rules and regulations, and so we did that here," she said.

But the rocket body was still subject to natural forces, which acted on it over time.

"What has happened is, essentially, a mixture of solar activity and gravity forces have put it on a path towards the moon," Scheiman said.

The Falcon 9 upper stage ended up slamming into the moon this morning at about 5,400 mph (8,690 kph). It likely blasted out a crater up to 89 feet (27 meters) wide, according to scientists' calculations.

This was certainly not the original intended outcome for this rocket. But it presents an opportunity for researchers, who plan to take advantage of it to learn more about the moon.

"NASA’s Meteoroid Environments Office will attempt to image the impact around the predicted time using ground‑based telescopes at the agency's Marshall Space Flight Center in Huntsville [Alabama]," Garner added. "Because the impact flash and plume are expected to be faint, the chance of seeing anything from Earth remains low, and local weather can affect observations as well. Any data collected will help scientists better understand impacts from artificial objects and the potential effects on future lunar exploration."

Today's impact took place on the sunlit side of the moon, the brightness of which made observations difficult for skywatchers hoping to watch the crash from afar with telescopes. But the two lunar orbiters might be able to see not just the crash and impact crater but also the plume of dust kicked up by the rocket's death dive.

So far, observations from Earth have revealed some information. Scientists at the Lowell Observatory in Flagstaff, Arizona reported detections of a lunar plume from the impact.

"We can safely say that we measured a response from the rocket stage impact as a sodium and lithium gas plume a few 10’s of kilometers in size lasting between 5 and 10 minutes after impact," Carl Schmidt told Inside Outer Space's Leonard David.

Such images of the event would provide "an opportunity to test pipelines for measuring flash properties to locate impact events seismically, and to better understand the multi-modal hazards posed to future lunar infrastructure and astronauts from space debris impacting the moon," researchers led by Benjamin Fernando of Los Alamos National Laboratory in New Mexico wrote in a recent paper discussing the then-upcoming event.

So hold tight, as researchers are now eagerly collecting and analyzing the images captured by these orbiters, and we might get images of the rocket crash, the lunar plumes and remaining aftermath soon.

A planet-hunting spacecraft named Plato just passed a series of critical tests as it prepares for the challenges of outer space.

What is it?

Gleaming in the light of a laboratory, this box of electronics is actually the European Space Agency's Plato spacecraft sitting inside a special test chamber where it underwent critical tests ahead of its planned spaceflight.

The Plato (PLAnetary Transits and Oscillations of stars) probe is designed to study terrestrial exoplanets, or rocky planets outside of our solar system that are Earth-sized or smaller.

This chamber, called the Maxwell Test Chamber (which is located at the European Space Research and Technology Centre in the Netherlands), is an enclosure made of conductive metal that blocks electromagnetic fields. On top of the conductive metal are foam spikes. Combined, they block out and/or absorb all electrical signals and sounds to mimic some aspects of the environment of the vacuum of space.

In this enclosure, the team turned on Plato's electronics to make sure that signals from some of the probe's instruments don't interfere with other systems or electronics on the craft. With all other signals blocked out, scientists had a clear look into how it might perform in space.

Why is it incredible?

This test is critical as Plato will need to be able to collect data and run its instruments without interference from electronics or signals from elsewhere on the spacecraft. But it's pretty impossible to ensure that things would work as planned amidst the "noise" on planet Earth.

To get any spacecraft ready to operate in the void of space, researchers conduct all sorts of tests to make absolutely sure that they're up to the challenge. In addition to tests like this, spacecraft can be placed in extremely hot or cold temperature chambers or even shaken around to make sure that they can handle the violent conditions of a rocket launch. It's amazing how we can recreate different aspects of outer space here on Earth to prepare for these missions.

LOS ANGELES — Standing in the shadow of the space shuttle Endeavour, a group of retired NASA astronauts announced their plan to travel the country visiting colleges to try to inspire younger generations to get out and vote. This campaign comes as we lead up to the November midterm election.

This past year, a group of retired NASA astronauts teamed up for a single cause: to defend the U.S. constitution. They banded together as part of a non-profit, non-partisan activist organization called Astronauts for America. So far, they have been speaking out, using their astronaut expertise, platforms, cultural relevance and role model status to speak out in support of "science, evidence-based decision-making, public service and the rule of law," their website reads. Now, as the group announced at an event at the California Science Center's new air and space center — home to the shuttle Endeavour — they're hitting the road on a campaign tour of colleges called "Vote for Freedom."

"We have to do what we can to ensure that the country makes it through the challenges that we're dealing with here, and that is the message that we're going to be taking to colleges and universities," Apollo 9 astronaut Rusty Schweickart told Space.com. "And the agency that we have, the immediate agency, is to vote."

This tour will send astronauts from the group on a four-month jaunt across the country. Astronauts from the group's more than 100 members will visit state and community colleges, county fairs and even town halls, aiming to reach first-time voters and young people who might be new to voting.

"I'm really excited to look a bunch of younger Americans in the eye and make sure that they know that someone that they can trust said: ;Listen, you matter, because our country matters, and our country needs you,'" former NASA astronaut Cady Coleman told Space.com.

"It's with a uniquely American kind of freedom that we were able to go to the moon, and that same freedom launched the spaceship behind us 25 times into space. Now we see those freedoms under heavy threat," former NASA astronaut Steve Smith said during the event. "We're seeing chaos instead of community, violence instead of votes, lies instead of laws, and fear instead of fate. That's how democracy and freedom die."

"The mission is all that matters. Now, our country is the mission, and our message is simple: going to the polls is one small step for you, and one giant leap for our country," Smith added.

This campaign leads up to the U.S. midterm elections this November. Midterm elections happen halfway through every four-year presidency. This election allows voters to decide what Congress looks like, and which political party controls Congress. This can ultimately have a major impact on what laws and decisions are passed moving forward, and whether Congress will reject or change actions by the president moving forward. And this group of astronauts is serious about the importance of getting people out to exercise their right to vote.

"I'm a child of the segregated South; I grew up in Columbia, South Carolina," former astronaut and NASA Administrator Charlie Bolden, who also serves as a steering committee member for Astronauts for America, said at the event. "I graduated in 1964. Anybody know what happened in 1964? The Voting Rights Act. So, as a person growing up in my hometown, it wasn't a guarantee that my mom and dad were going to be able to go out and vote. I look at what's going on today about people trying to restrict the ability of people to cast their ballot. That's not who we are. That's not America."

The group of astronauts recently spoke out about voting access after the U.S. Supreme Court ruled in favor of protecting the right to absentee voting, in response to attempts by the Trump administration to place restrictions on the current voting process. Especially leading up to the November midterms, each vote carries significant weight. And while this nonpartisan group isn't telling you who to vote for, they do think that everyone who can should vote.

"As astronauts, we signed an oath to our nation, and we are mission-oriented people. And our nation is now the mission," Coleman added. "We need to recognize that everyone's voice is important, and one of the voices that we don't hear very much is the young people. And we want them to understand that, even though sometimes change can seem daunting, their perspective is really important, and, you know, their voice is important."

In satellite data captured over Antarctica, what appears to be a beautiful, colorful hummingbird emerges from the crest of a mountaintop.

What is it?

While there are no hummingbirds flying around Antarctica, we can see what looks like a small, purple bird in a new satellite image of an Antarctic mountain. The dark belly of this "bird" at the center of this image is actually the top of the mountain Nunatak Zaterjavshijsja in East Antarctica.

What looks like a bird's tail is a stream of ice flowing northeast all the way out to the ocean, and what appear to be feathers splaying outward from the mountaintop are actually crevasses down the mountain. These crevasses are formed by a glacier fracturing the mountain's surface as it flows in the icy current toward the ocean.

This view was captured by radar instruments onboard the satellite NISAR (NASA-ISRO Synthetic Aperture Radar) that launched as a collaboration between NASA and ISRO (Indian Space Research Organisation). The director of NASA's Earth Science Division called NISAR "the most sophisticated radar we've ever built" in a pre-launch briefing last year.

Why is it incredible?

At first glance, this image is puzzling. What could it possibly be? Its bold colors and sharp lines evoke almost alien qualities. But the strange beauty of the shapes and colors in this satellite image reveal important information about glacier movements on the mountain.

"First, it's a beautiful image, with rich details of features that provide insights to how the glacier is moving. Then, because radar can often see through snow and deep into the ice, NISAR can observe fundamentally different properties of Antarctic ice than can be seen in optical imagery," Seongsu Jeong, the signal analysis engineer who produced the image at NASA's Jet Propulsion Laboratory, said in a statement. "With NISAR we're seeing what's hidden beneath the surface."

And now anyone can explore NISAR's data. Earlier this week, on July 20, NISAR started making the data from its radar instruments public. Moving forward, mission teams will be rolling out this data so researchers everywhere can use it to study and protect our ever-changing planet.

You're looking at history. What might seem like a simple black-and-white picture of some rocks is actually the first photograph ever taken on the surface of Mars.

What is it?

Bright and early on the morning of July 20, 1976, NASA's Viking 1 lander touched down on the surface of Mars. This moment 50 years ago marked the first fully successful touchdown on the Red Planet, and, pretty much as soon as it landed, Viking 1 captured the first image of the Martian surface.

The Soviet Union had already made multiple Mars landing attempts, all of them failures to some degree. The nation's Mars 3 lander did manage to survive its landing initially in December 1971, but it lost contact less than two minutes later.

Viking 1 did more than just survive. While its mission tasked the lander with studying the planet for 90 days after landing, it lasted over six years on the planet and made some incredible observations. The Viking 1 lander worked in tandem with an orbiter by the same name, and was soon joined at Mars by Viking 2, another lander/orbiter pair.

Why is it incredible?

It has now been 50 years since Viking 1's historic first, which opened our eyes to the Martian surface. And NASA has kept improving technologies and exploring further on Mars ever since. Agency rovers began scouring the planet's surface in the 1990s, so we have gathered data on the planet's surface for decades upon decades at this point.

But in 1976, no one had ever seen the surface of Mars close up. This view was preceded by science fiction like Ray Bradbury's "The Martian Chronicles," which painted fantastical possibilities about what it might really be like on Mars. With Viking 1's view, we finally got some concrete evidence of the reality on the planet.

In 50 years, our understanding of Mars, our solar system and beyond has grown tremendously. But with each major accomplishment, we can look back at previous milestones such as this to see the stepping stones that paved the way to get us there.

A young cluster of galaxies sparkles under a cosmic glow that's 4.4 billion years old. This peek into the past shows the stellar spectacle of a galaxy cluster still forming.

What is it?

The James Webb Space Telescope snapped this image of the galaxy cluster MACS J0553.4-3342 on July 3 using its near-infrared camera (NIRCam). The glorious, glimmering sight is actually a massive young galaxy cluster forming 4.4 billion years ago. A galaxy cluster is a grouping of galaxies held together by gravity. Galaxy clusters can contain hundreds or even thousands of galaxies and are the largest known structures in the entire universe that are held together in this way.

Why is it incredible?

Because light takes time to travel through space, and because the JWST can look incredibly far out into space, this telescope acts as a sort time machine.

This power isn't unique to the JWST, however. Other telescopes like the Hubble Space Telescope, for instance, have similarly peered back in time through the cosmos and revealed some incredible, ancient sights. However, the JWST's specialized instruments like NIRCam allow the telescope to pick up incredibly faint light from galaxies remarkably far away. This greatly stretches how far back in time we can see.

But the really incredible thing is, you can look back in time yourself — with only your eyes. While JWST can look exceptionally far out into space and can capture the very faint light of ancient galaxies, the light coming from the stars you can see with your bare eyes also had to travel over incredible stretches of time to reach you. Think about this: the light coming from a constellation you love may have traveled across millions of light-years to get to your eyes.

The wildfires tearing across Canada are so extreme that the smoke billowing upward can be seen from space.

What is it?

Over 850 wildfires are currently devastating Canada, as reported by the Canadian Interagency Forest Fire Center. The fires are spreading across Manitoba, Saskatchewan and Ontario; most remain completely uncontrolled.

In addition to the immense destruction caused by the fires themselves, the smoke from these fires is causing serious concerns about dangerously poor air quality all across Canada and even in the northeastern United States. As far as New York, the air quality on Thursday (July 16) was labeled "very unhealthy" after the state activated emergency air quality protocols.

The smoke is so expansive it's clearly visible in this image captured on July 14 from Earth orbit.

Why is it noteworthy?

Studying wildfires and wildfire smoke from orbit can give us a bigger picture view of these catastrophic event. This data is important for disaster relief in the short term — but also in the long-term. With climate change continuing to progress due to human activities like burning coal for cheap power, we can expect natural disasters to worsen. Among the many effects of climate change, this includes longer and more intense wildfire seasons, especially in regions that are already susceptible to fire such as these regions across Canada.

The new image was captured by the NOAA-21 satellite with the instrument VIIRS (Visible Infrared Imagine Radiometer Suite). You can see massive plumes of smoke over southeastern Canada treading into the northeastern U.S. Thick smoke covers swaths of Canada's landscape and wisps of smoke trail all the way down through New York and across the U.S.

Most of this smoke, at least the smoke we can see in this satellite image, is coming from wildfires in northwestern Ontario. As the wildfires continue to burn, satellites like NOAA-21 will be keeping watch.

This might be the closest we've gotten to finding a planet that could support life: Astronomers have detected an atmosphere around an Earth-like, rocky planet orbiting in the habitable zone around its star, a monumental first.

The rocky planet, called LHS 1140 b, is 48-light-years away from Earth and according to this new research, it has an atmosphere that contains helium. It is also the first rocky planet to have an atmosphere be detected directly. This is the first rocky planet to be found with an atmosphere that is also in the habitable zone, meaning it's at the right distance away from its star for liquid water to potentially exist on the planet. As we continue to search the cosmos for planets that can be considered "habitable," this planet checks more boxes than almost anything we've ever seen.

"We have actually detected directly the helium present in the atmosphere itself, and that's the first direct detection for any rocky exoplanet, which is really exciting … and then there's this added bonus that it's in the habitable zone, which is super exciting for astrobiology and habitability and searching for life," lead author Collin Cherubim, who recently earned his Ph.D. from Harvard University, told Space.com. "It feels kind of surreal."

What's this planet like?

Let's explore this planet and the system where it "lives."

This exoplanet, or planet outside of our solar system, was first discovered in 2017 by a team led by astronomer Jason Dittmann who is now a co-author on this new discovery.

"This planet was found like 10 years ago, and we're just now saying, okay, that's an atmosphere," Dittman told Space.com. "We're slowly narrowing the gap and checking these boxes … we're finding a planet that's rocky, a planet that's of the right temperature and now … it's like okay, we finally found one that has an atmosphere."

And being a rocky planet, "there's definitely a surface … it's made of rocks," Dittman said. What does the planet's surface look like? We can't say yet, but the researchers who found this planet's atmosphere think there's a good chance it could have water.

While it orbits a red dwarf star, which is smaller and cooler than the sun, it orbits closer than we do to our star, maintaining a temperature that keeps the planet in the "Goldilocks zone" where liquid water could exist on its surface.

"It probably also has a lot of water," Cherubim said. "If it has some amount of atmosphere that can provide a bit of a greenhouse effect, which we know that it does now … it will very likely be what we consider to be habitable conditions on Earth, and conditions that would likely support liquid water."

So is it Earth-like? While it's certainly not an Earth copy, this planet can be considered Earth-like in two main ways, Cherubim shared. One: its overall composition. The planet is rocky, likely with an iron core and (now we know) it has an atmosphere. And two: the planet's temperature is just right for liquid water, which is necessary for life at least as far as we understand it on our planet.

Finding an atmosphere

The discovery of the first exoplanet was confirmed just over 30 years ago. Since then, scientists have found over 6,000 exoplanets and counting. And while a few rocky planets have been found in their star's habitable zone, it wasn't until now that an atmosphere has been confirmed around a rocky planet in the habitable zone.

One reason why scientists have had a hard time finding such planets with atmospheres is their stars. LHS 1140 b orbits the most common type of star, a red dwarf, which is about one-third the size of our sun. This type of star remains active for a lot longer than stars like our sun. This activity means it releases bursts of extreme radiation like solar flares and coronal mass ejections. And typically, the extreme radiation around these stars totally strips the atmospheres from the planets orbiting them, so astronomers have wondered if planets orbiting these stars can have an atmosphere at all.

"This discovery is a big deal because it's showing that at least this rocky planet has retained an atmosphere over billions of years," Cherubim said. It's "a bona fide, robust way of saying yes, atmospheres can survive on rocky exoplanets."

It's possible that other gases beyond helium are in the planet's atmosphere, and it's possible that some of its atmosphere was previously stripped away by its star's radiation. But the red dwarf that this planet orbits is roughly 6 billion years old, a few billion years older than the age at which their extreme radiation activity begins calming down. So while some helium is still slowly escaping the planet's atmosphere over time, the team expects the planet to retain an atmosphere, Dittman shared. After all, even Earth's helium is slowly escaping our own atmosphere.

The proof is in the atmosphere

To prove that this planet has an atmosphere, the team started with a prediction that Cherubim made during graduate school. It all started with a theoretical model and a sneaking suspicion that there must be rocky exoplanets with atmospheres other than Earth.

"This came out of a very specific prediction from a planetary evolution model that I actually developed myself, from scratch, from first principles, for my Ph.D. as a theorist, and I made a very specific prediction about this planet," Cherubim said. "And then I went out and did a pretty unexpected, weird thing using this technique that's typically reserved for observing giant planets, and I used it for a rocky planet, which nobody has done before.

"And lo and behold, I made this measurement that was actually consistent with my prediction. And it was really nice to kind of close the whole loop of the scientific method."

The team took the theoretical model that Cherubim developed in graduate school and put it to the test using the Warm Infrared Echelle (WINERED) Spectrograph on the Magellan Observatory in Chile. And with their observations, they were able to see LHS 1140 b and another planet both transit, or pass in front of, their star in the same night. With this spectrographic data, they could identify the signatures of molecules in the atmospheres of these planets as they passed in front of the star. And while one planet yielded no results, this planet showed a direct, undeniable helium signature.

Are there aliens?

When looking at a planet that is rocky, has an atmosphere, and is in the habitable zone (meaning it could have liquid water), the question of life comes up quite quickly.

But the researchers don't have enough data to make that conjecture. "I'm not claiming this planet has life," Cherubim made clear. With further investigation, scientists could better understand what else might be in this planet's atmosphere, and they could confirm if it has water. Further observations might not be able to confirm habitability or identify any life on the planet, but they could at least help us to better understand planets like this.

With this being the first planet of its kind discovered, further exploration will help us to put the pieces together. But it is certainly a major step forward in the eternal human quest to answer the question: are we alone?

This work was described in a study published in the journal Science.

A laser star guide beams up from the Gemini South Observatory and into the Milky Way on Cerro Pachón, a mountain in central Chile.

What is it?

The Gemini South Observatory, located in Chile, is one of two Gemini Observatories with the other located in Hawaii (named Gemini North, or 'Alopeke) on the volcano Mauna Kea.

Each Gemini Observatory has a 26.6-foot (8.1-meter) telescope. On the same mountain in Chile sits the 13.4-foot (4.1-meter) SOAR telescope.

In this photograph captured by Petr Horálek, an audiovisual ambassador for the U.S. national center for ground-based, nighttime optical astronomy at NOIRLab (the National Optical-Infrared Astronomy Research Laboratory), it looks like Gemini South is about to be beamed up into the night sky.

However, there isn't some alien ship behind that laser beam. Instead, Gemini South is beaming up a laser guide star, or a powerful laser that creates the appearance of a fake star in the night sky. This fake star acts as a reference point, helping the telescope to calibrate and correct any light distortions.

Why is it incredible?

Even from just this photograph, which shows an observatory in action, it's clear why this mountain is a hotspot for astronomical observing.

These peaks are chosen for many reasons, including their altitude and how far they are from bright lights that could affect observations. But even in a regular photograph, Horálek was able to show the incredible beauty of the glow of the Milky Way's heart above the mountain range, with every color in the rainbow popping up in the gas and dust across our galaxy.

Even the framing of the shot draws you in, as the viewer feels almost pulled down the road toward the observatory and right up into the Milky Way.
