Using NASA’s Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, but two long-standing questions in astrophysics.
These mysterious objects give off unusually low-energy X-rays but intense levels of ultraviolet radiation. This discovery is featured in a paper published Wednesday in Nature Astronomy.
“We’ve never encountered a group of objects that act like this,” said Mustafa Muhibullah of the University of Alabama who led the study. “Of course, the next step was to try to figure out what these things are.”

The researchers found a total of 84 of these “hypersoft X-ray sources” – so named because they give such low-energy X-rays – in the six different galaxies they searched, using data openly available to the public in the Chandra archive. Two of the galaxies are spirals, M31 (the Andromeda galaxy) and M101 (the Pinwheel galaxy), while the other four are ellipticals. They found hypersoft X-ray sources both in regions of active star formation and areas where there are older stars.
The team spotted the sources by finding objects that appeared in Chandra images taken at the lowest X-ray energies but vanished in higher-energy images. That means these objects give off far more low-energy X-rays than high-energy ones. Because low-energy X-rays border energetic ultraviolet radiation on the electromagnetic spectrum, the researchers determined that these sources are producing large amounts of energetic ultraviolet radiation as well.
It is unclear what types of objects are responsible for these low-energy X-rays and intense ultraviolet radiation. The team thinks they most likely involve a black hole, neutron star, or white dwarf pulling material from a companion star. The material pulled from the companion star is heated up to produce X-rays before falling onto the white dwarf or neutron star, or into the black hole. Such binary systems have been seen before, but not with such bright ultraviolet radiation and low-energy X-rays.
The discovery suggests that there may be large populations of binary systems with energetic ultraviolet radiation that have been undetected until now.
“These clandestine X-ray sources are actually among the most energetic objects in galaxies, and they could be solving two cosmic mysteries at once,” said Muhibullah.
Scientists think that some white dwarf systems pulling material from companion stars may eventually explode as a supernova – known as a Type Ia – that is critical for measuring the expansion of the universe. These supernovae played a key role in discovering that this expansion is accelerating. Astronomers have been looking for the stars that turn into Type Ia supernovae for many years, so far without success.
“If we could find a way to spot these Type Ia supernova explosions before they go off, that would be really important,” said co-author Jimmy Irwin, also of the University of Alabama. “Right now, we study them after they’ve exploded, and astronomers have struggled to understand what is actually ignited.”
The other mystery these hypersoft X-ray sources might explain is what strips electrons from gas between the stars in some galaxies. This stripping of electrons is important to probe because it can affect how quickly stars form and influence the life cycles of galaxies. Hot, massive stars play a role, but they do not completely explain what is causing this stripping. The intense levels of ultraviolet radiation from the hypersoft X-ray sources may play a vital role.
Why were these hypersoft X-ray sources not found until now? In addition to the low-energy X-ray output, which is very difficult for X-ray telescopes to detect, the high-energy ultraviolet radiation is readily absorbed by helium and hydrogen gas that fills the space between the stars, creating a nearly impenetrable barrier to look through.
“By combing through the Chandra archive, we were able to eliminate what used to be a blind spot for telescopes,” said co-author Rosanne Di Stefano of the Center for Astrophysics | Harvard & Smithsonian. “That’s how we found what appears to be a new class of cosmic objects with remarkable qualities.”

This release features a composite image of a spiral galaxy, M101; one of six identified galaxies housing a new class of mysterious objects that give off unusually low-energy X-rays.
In this composite image, M101 faces us directly. It has multiple arms in shades of purple, spiraling clockwise around a golden yellow core. Scattered along and between the arms are scores of tiny specks in white and purple. Most of those specks are pairs of stars, but seven of them are a mystery.
To casual observers, the unusual objects are visually indistinguishable from the other specks of light in the galaxy. An annotated version of the composite image is included in this release, with red circles around the mysterious specks for easy identification.
These mystery specks behave like no other class of object discovered before. The curious objects give off X-rays of such low energy, they in fact produce large amounts of ultraviolet radiation, as UV radiation borders X-rays on the electromagnetic spectrum. Searching images of galaxies with low-energy X-rays in the Chandra Observatory archive, scientists have found a total of 84 such objects spread across M101 and five other galaxies. They have dubbed these mysterious objects “hypersoft X-ray sources.”

NASA Telescopes Create Colorful ‘Craft’ From Nearby Nebula
Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA space telescopes. The resulting cosmic “craft” reveals new details about the star formation region known as 30 Doradus, or the Tarantula Nebula.
Located in the Large Magellanic Cloud, a small neighbor galaxy to the Milky Way about 160,000 light-years from Earth, the Tarantula has thousands of young stars embedded in a vibrant honeycomb-like structure of gas and dust.

Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA space telescopes. The resulting cosmic “craft” reveals new details about the star formation region known as 30 Doradus, or the Tarantula Nebula.
Located in the Large Magellanic Cloud, a small neighbor galaxy to the Milky Way about 160,000 light-years from Earth, the Tarantula has thousands of young stars embedded in a vibrant honeycomb-like structure of gas and dust.
The new composite image contains X-rays from NASA’s Chandra X-ray Observatory, which has repeatedly observed the Tarantula Nebula over the course of its mission, in the layer that appears in blue. The X-ray data reveals gas blown away by winds from the surfaces of young, massive stars and heated to millions of degrees by shock waves, like sonic booms from supersonic jets.
The red represents infrared data from NASA’s James Webb Space Telescope showing thousands of young stars, plus swaths of cool dust that will provide the ingredients to form new stars and planets. Optical data in the green layer from NASA’s Hubble Space Telescope uncovers hydrogen gas that is warmer than seen with Webb, as well as some individual stars through the nebula.
The composite image shows the full Hubble and Webb images of this region, as well as a large section of the Chandra image, all recently published in a research paper in the Astrophysical Journal. In some regions the blue Chandra layer stands alone, and in others it combines with either the red Webb data or the green Hubble data. In the middle region all three images overlap to provide a holistic view in red, orange, yellow, green, and blue.
Previously, astronomers had studied the amount and the impact of energy produced by winds from young, massive stars in the Tarantula Nebula. Scientists expect that much of this energy should heat gas so that it produces X-rays. However, the research paper shows that there is much less X-ray-emitting gas in the nebula than expected. This led researchers to ask: Where has this energy gone and what tamed the Tarantula Nebula?
By studying the data from Chandra, Hubble, and Webb, combined with data from NASA’s retired Spitzer Space Telescope, the team concluded the Tarantula may be losing energy from several sources.
First, up to half of the hot gas is leaking through the shell walls of the gas and dust structures and escaping the nebula. Next, there is stirring and mixing between the cold gas near the shell walls and some of the hot gas, lowering the overall temperature of the gas. Finally, comparisons with computer simulations suggest the Tarantula may be losing energy through conduction. This involves direct physical contact between hot and cooler material, like with a frying pan on a burner, causing the hot and cooler material to equalize in temperature. In the case of the Tarantula Nebula, the hot gas would be conducting heat by being in direct contact with the cooler gas in the shells, especially in the densest regions. This scenario does not necessarily involve mixing the hot and cooler gas.
The combination of these three channels for losing large amounts of energy leads to this colorful and complex display revealed by NASA’s telescopes working together.

As NASA sets its sights on long-term exploration of the Moon and Mars, the agency is increasing the cadence of its Artemis missions. Helping bring these plans to fruition is Tom Percy, manager of systems engineering and integration for NASA’s Human Landing System Program.

Percy serves as a focal point in working with providers SpaceX and Blue Origin to accelerate and streamline systems designs, manufacturing, testing, and certification. He ensures the crewed landers that SpaceX and Blue Origin are developing for Artemis are designed, built, tested, and will operate with other NASA exploration assets safely and effectively.
“You might say that all human landing system integration work lands on my desk. And with the rest of my talented, hard-working systems engineering and integration team, we’re working to make it all happen,” Percy said.
A native of North Easton, Massachusetts, Percy earned a bachelor’s degree in mechanical engineering from the Rochester Institute of Technology in Rochester, New York, where he first got hands-on experience working on designs that could be applied to NASA’s sustainable lunar architecture.
“As an undergrad, I served as president of the Rochester Institute of Technology’s chapter of the American Society of Mechanical Engineers. To get some real-world engineering experience, we decided to participate in the Great Moonbuggy Race,” Percy said. “Now called the Human Exploration Rover Challenge, the competition is held annually at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
“At the time, I had never heard of Marshall Space Flight Center,” said Percy. “But our student team designed and built a rover and traveled to Huntsville for the race. That’s when I learned about some of the projects in Marshall’s diverse portfolio that the center works for NASA. And that’s when I began planning to make my way to NASA Marshall for my career.”
Percy chose to move south and earn a master’s degree in aerospace engineering from the Georgia Institute of Technology in Atlanta. His research in the advanced propulsion lab and courses in space systems design culminated in a spacecraft design course and the chance to work directly with engineers at Marshall.
Since landing at Marshall in 2003, Percy has been involved in evaluating transportation architecture options for human deep space exploration, including missions to land astronauts on the Moon and Mars. He also has expertise in space transportation, including advanced propulsion technology development; trajectory analysis; and spacecraft and mission concept development. Percy earned a doctorate in aerospace systems engineering from the University of Alabama in Huntsville.
The range of experience comes together in his current role as manager of human landing systems engineering and integration.
“The world watched the amazing success of Artemis II. NASA and our commercial providers are looking forward to flying again soon and executing increasingly complex Artemis missions,” Percy said.
Through the Artemis program, NASA will send astronauts on increasingly complex missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.
NASA, SpaceX Advance Wind Tunnel Tests for Starship Rocket

NASA and its industry partners are preparing for next year’s Artemis III demonstration mission by completing new wind tunnel tests on SpaceX’s Super Heavy Version 3 rocket booster. The tests, conducted at NASA’s Ames Research Center in California’s Silicon Valley, focused on better understanding the extreme aerodynamic forces the rocket can experience during re-entry. The recent test series builds on previous testing completed at NASA Ames in 2024.
NASA is working with SpaceX to develop the company’s Starship Human Landing System (HLS) to safely carry astronauts from lunar orbit to the Moon’s surface and back. The upgraded Super Heavy rocket booster is part of SpaceX’s Starship launch system. Version 3 of Starship and Super Heavy is expected to be the basis for the Starship HLS for Artemis III in 2027 and a later crewed lunar landing in 2028.

Although Starship HLS is a lunar lander designed and built by SpaceX, NASA collaborates with commercial companies to provide access to specialized testing facilities, like the wind tunnels at NASA Ames, and technical expertise, such as the team that set up the wind tunnel testing and helped analyze the results.
“NASA has a lot of experience with unsteady aerodynamics,” said Manish Mehta, discipline lead engineer for the HLS Plume and Aero Environments team, NASA’s Marshall Space Flight Center in Huntsville, Alabama. “We used the agency’s broad experience base of conducting wind tunnel tests for the space shuttle, the SLS (Space Launch System) rocket, and Orion spacecraft to efficiently set up and analyze the wind tunnel testing for the Super Heavy Version 3. In fact, similar testing at the Ames Unitary Plan Wind Tunnel resulted in adding strakes to SLS for Artemis II, so what we learned for Artemis II is helping us get to Artemis III and beyond.”
Testing
SpaceX’s Starship consists of a 33-engine first-stage Super Heavy rocket, or booster, and the second-stage Starship. Version 3 of Super Heavy incorporates many new and upgraded systems, including:
New propulsion systems and new Raptor 3 rocket engines
No engine section skirt, individual engine shrouds, or integrated large-scale base heat shield
Three gridfins on the Super Heavy booster instead of four, with each fin now 50% larger
An integrated hot stage replacing the previous single-use protective interstage
With significant changes to Super Heavy, NASA and SpaceX engineers wanted more information about the steady and unsteady aerodynamic forces the rocket will experience during atmospheric re-entry as it returns to the launch site for refurbishment and re-use.
“When a rocket, or an airplane, flies through air at high speed, it’s subjected to steady aerodynamic forces and moments, and unsteady aerodynamic forces and moments,” explained Jayanta Panda, unsteady aerodynamics subject matter expert at NASA Ames and part of the Human Landing System Plume and Aero Environments team. “An example of a steady aerodynamic force would be when air smoothly flows over the surface of the rocket as it ascends. An unsteady aerodynamic force would be air ‘buffeting,’ or hitting, certain areas the rocket at less predictable times and potentially causing vibrations.”
Wind tunnels
NASA and SpaceX used a 1.2% scale model of the Super Heavy Version 3 in the transonic wind tunnel and the supersonic wind tunnel at NASA Ames for testing. The transonic tunnel blasts scale models of rockets or aircraft with air at speeds ranging from Mach 0.2 to Mach 1.4 (Mach 1 is the speed of sound, or about 761 miles per hour). The smaller supersonic tunnel fires winds at higher speeds, from Mach 1.55 to Mach 2.5. The wind tunnel tests on Super Heavy Version 3, conducted in late 2025, used both tunnels to measure steady and unsteady air flows on the surfaces of Super Heavy.
“Resulting wind tunnel data on steady forces and moments helps predict how the rocket will react to forces in the atmosphere during re-entry so the flight software can effectively guide the rocket during flight,” Mehta said. “The unsteady pressure data helps engineers understand the environment around the rocket as it re-enters Earth’s atmosphere. Engineers use that information as one input into software that analyzes loads on the rocket.”
Through the Artemis program, NASA is returning humans to the Moon for scientific discovery, economic opportunity, to establish an enduring human presence on the lunar surface, and build the foundation for the first crewed missions to Mars – for the benefit of all.
How NASA’s Artemis III Lander Test Will Pave Way for Moon Landings
Before Artemis astronauts land on the Moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the Moon, will support astronaut safety and mission success for crewed lunar landings.
NASA is working with two American companies to develop the human landing systems that will safely transport astronauts from lunar orbit to the Moon’s surface and back for future Artemis missions. For Artemis III, both SpaceX and Blue Origin will fly test versions, or test articles, of the crewed landers that will be used for future Moon landings. The lander test articles will launch by commercial rockets, while the Artemis III crew will launch to low Earth orbit in Orion atop the agency’s SLS (Space Launch System) rocket.
Stage setting for crewed flights
NASA and the human landing system providers have been working closely together to plan and determine capabilities for the Artemis III mission. With missions fast approaching, both SpaceX and Blue Origin are optimizing hardware availability and capability. SpaceX plans to use the company’s latest version of Starship and basis of the future Starship HLS, called Version 3, while Blue Origin will test their planned HLS crew cabin, allowing each company to apply lessons learned prior to uncrewed and crewed missions on the Moon.
“Each human landing system provider has taken a different approach to the Artemis III mission,” said Steve Creech, program manager, Human Landing System Program, NASA’s Marshall Space Flight Center in Huntsville, Alabama. “Ultimately, SpaceX and Blue Origin have put forward a list of aggressive objectives and goals intended to complement upcoming uncrewed demonstration missions at the Moon so that we can gain both understanding and confidence in the spacecraft and launch vehicles prior to a crewed landing. The lander prototype designs will inform future development efforts and will continue to mature over the next year.”
For the Artemis III mission, the Blue Moon test lander will be based on Blue Origin’s current architecture for its Mark 2 crew lander, incorporating all the major avionics and flight software and control systems to ensure flight operations from this demonstration mission can directly translate to crewed lunar flights. Up to two crew members, donning orange Orion crew survival system suits, will open the hatch to enter the Blue Origin test lander. The production hardware must incorporate many of the same systems and subsystems, including an Environmental Control and Life Support System (ECLSS), a crew cabin, and avionics.

The Blue Origin lander also will fly with an instrumented lunar surface spacesuit mass simulator. Like the suited “Moonikin” manikin that flew aboard Orion during the uncrewed Artemis I test flight, the low-fidelity spacesuit mass simulator will provide real-time feedback about the environment within the Blue Moon crew cabin.
SpaceX’s Starship lander test article will use a Starship Version 3, currently in production and testing, with an added docking system installed on the nose of the 171-foot (52-m) spacecraft, enabling NASA and SpaceX to evaluate how the entire integrated stack of Orion and the Starship test lander interact. NASA and SpaceX are identifying controllability and communications tests for the Artemis III mission. Astronauts will not enter the Starship test lander during Artemis III.

Launch cadence
NASA, SpaceX, and Blue Origin will launch three of the world’s most powerful rockets within a short timeframe of one another, exercising ground processing, launch crews, and facilities as well as control centers, networking, and data exchange at key sites across the country during two separate, back-to-back rendezvous and docking maneuvers between Orion and the lander test articles, before a safe splashdown of the Artemis III crew in Orion.
“Artemis III will be a highly choreographed dance with a demanding launch sequence across multiple launch pads and equally demanding mission operations for our ground and flight crews, making it one of the most complex and ambitious missions NASA has ever undertaken,” said Jeremy Parsons, Artemis program manager. “The demonstration mission will set the stage before our next giant leap. NASA’s expertise in systems engineering and integration, as well as launch and mission operations in low Earth orbit, will bring the mission together.”
For future crewed missions to the Moon, NASA and one of the commercial lander partners will execute a “dual launch campaign,” prepositioning the lander in orbit to await a crewed Orion, launched on SLS. Launching the three rockets in succession of one another for Artemis III offers a unique opportunity to practice launch processing and operations.
Blue Origin’s lander test article is planned to launch first and will be able to loiter in space for up to 30 days, allowing for checkouts in orbit prior to the launch of SLS and Orion from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. The Blue Origin test article will launch at a set trajectory to meet a designated “parking” orbit for these systems checks.

Artemis program manager
Following the completion of Blue Origin’s rendezvous and docking operations testing and the Artemis III crewed launch on SLS, SpaceX will launch its Starship lander test article to rendezvous with Orion and its crew for its phase of on-orbit testing.
Throughout the Artemis III mission, Orion will fly in a circular orbit. All three rockets will have more launch opportunities than are available for a lunar mission and will be able to reach the designated mission altitude in a single launch.
Docking operations
During docking and undocking operations, Orion and the Artemis III crew will use the lander test articles as the targets, while Orion will operate as the chaser spacecraft. This is the same configuration planned for future crew landing mission to the Moon.
NASA will ensure both test landers are mission ready and crew safe prior to Artemis III. These verifications will be based on functional and performance requirements for the test lander designs and hazard controls for hardware and software, ensuring the Artemis III astronauts inside Orion are safe throughout both docking phases of the mission.
SpaceX and Blue Origin have already tested their docking capabilities for their respective landers on the ground. SpaceX’s docking capability was qualified in 2023; Blue Origin conducted development ground testing on its pressurized docking system earlier this year.
A key difference between the docking capabilities of both lander test articles will be the location of docking. Orion will dock along the side of the Blue Moon test lander, adjacent to the crew cabin. Later, Orion will dock nose-to-nose with the giant SpaceX test lander.
Software testing between spacecrafts will help demonstrate that the commercial human landing system prototypes and Orion can meet at a precise time and location in space. When Orion docks with the Blue Moon test lander, the Orion spacecraft’s software will control the docked spacecraft. Meanwhile, the SpaceX test article will control the docked spacecraft for the second portion of the mission. During the docking phases, teams with NASA and the commercial partners will be able to test hardware and software interoperability, as well as dynamics of how the integrated lander-Orion spacecraft moves in space.
Through the Artemis program, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.
NASA’s Chandra Finds Unexpected Fireworks in Aftermath of Stellar Explosions

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA’s Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they did not expect to find a population of supernova remnants, or the debris from these explosions, showing dramatic changes in their brightness. The new results were presented at the American Astronomical Society meeting in Pasadena, California, and published in The Astrophysical Journal.
The galaxy M83, located about 15 million light-years from Earth, is forming stars at a high rate. Researchers analyzed 14 years of Chandra data of the galaxy, spanning 2000 to 2014.
Using this extensive set of data, the researchers caught surprising variations in the X-ray brightness of sources previously identified as supernova remnants. The researchers expected supernova remnants older than a century or so to fade gradually in X-rays, but not change dramatically in brightness.
The team found that roughly half of the 22 X-ray sources associated with supernova remnants in their sample showed changes in X-ray brightness over the 14-year span of observations — a result that was completely unexpected.
“We knew that individual X-ray sources could vary dramatically,” said Andrea Prestwich, of the Catholic University of America who led the study. “But finding that so many supernova remnants were behaving this way was a real surprise. Something unusual is going on in these objects. Pinpointing the cause remains a challenge, as M83’s distance limits the detail we can observe.”
One of the 22 variable supernova remnants has a straightforward explanation: SN 1957D, the debris from a supernova first observed nearly 70 years ago, is ramming into material surrounding the explosion site, producing the observed X-ray flares. But this cannot explain the rest of the sample. There is no evidence to suggest that all 22 remnants were formed within the last century. Something else must be driving the variability.
The most likely explanation is that the team has uncovered a population of stellar survivors stars that lived through their partner’s destruction in a supernova explosion. In this scenario, each variable X-ray source began as a pair of massive stars orbiting each other. The more massive star collapsed and exploded as a supernova, leaving behind a black hole or ultra-dense neutron star. Its companion survived.

“It may be that this galaxy contains a collection of supernova remnants where one massive star survives the supernova and becomes locked into an orbit with a black hole or neutron star,” said co-author Michael McCollough of the Center for Astrophysics | Harvard & Smithsonian (CfA). “The neutron star or black hole can then start pulling material from the massive star’s surface.”
That infalling material is superheated by the intense gravitational pull, producing the X-rays Chandra detects. These types of systems, known as high-mass X-ray binaries (HMXBs), are among the most variable X-ray sources in the universe. Researchers say they may be the cause of the variations seen in M83’s supernova remnants.
Astronomers have known about HMXBs for decades, but the difference with this group in M83 is their connection to supernova remnants. Previously, only a handful of supernova remnants associated with HMXBs had been identified across observations of all galaxies. It is unprecedented to find more than 20 strong candidates in just one galaxy.
The authors found that the variable supernova remnants are in regions with higher concentrations of massive stars than in other parts of the galaxy, increasing the chances of a link between the remnants and HMXBs.
There is another possible explanation: Instead of pulling in material from a companion star, the black hole or neutron star may be recapturing some of the material blasted outward by the original explosion.
“This could be an example of cosmic recycling, where debris from the explosion falls back onto the very object the supernova created,” said co-author Roy Kilgard of Wesleyan University. “And it’s quite possible that both explanations are at play — different sources in our sample may have different origins.”
These results are not unique to M83. A follow-up study of the nearby star-forming galaxy M51 by Zoe Hoiland of Vassar College and Kilgard has uncovered a similar population of variable X-ray sources associated with supernova remnants, suggesting that such systems may be a feature of galaxies undergoing vigorous star formation.
This is a composite image of the galaxy M51 combining data from NASA’s Chandra X-ray Observatory (purple) with optical data (red, green and blue) taken with ground-based telescopes by a team of astrophotographers. A surprisingly high number of X-ray sources associated with supernova remnants in M51 show large changes in brightness, similar to the behavior seen in M83.

The Chandra data for M83 began with single observations in 2000 and 2001, followed by 10 observations from 2010 to 2011 and another observation in 2014.

In the composite image, Messier 83, or M83, is shown to have a spiral structure, viewed straight on. At the center is a brilliant white and yellow pool of light. From that light, spiral arms of hot pink cloud corkscrew out in wide, sweeping arches. The galaxy is covered in a faint grey haze, and flecked with red, green, blue, white, and yellow dots.
In an annotated version of the composite image, two tiny dots to our lower right of center are highlighted by white circles. These are two of the supernova remnants being considered by researchers. Each is examined further in a separate timelapse video.
Over a 14-year period from 2000 to 2014, astronomers pointed NASA’s X-ray observatory at the M83 galaxy. They discovered that about half of the X-ray sources believed to be supernova remnants, the aftermath of stellar explosions, were exhibiting dramatic changes in brightness. This result was entirely unexpected.
Those changes in brightness are highlighted in the timelapse videos. In each video, a series of static images flashes by, focused on one of the two X-ray sources once believed to be supernova remnants. In the videos, the X-ray sources appear as bright blue blobs with glowing cores. But in each image, taken months or years apart, the shapes change, as does the intensity of the blue color, and the brightness of the core. By presenting the substantively different images of the same objects one after another in quick succession, short timelapse videos are created.
The most likely explanation for the changes in brightness is that the team has uncovered a population of stellar survivors, stars that lived through an orbiting partner’s destruction in a supernova explosion. Material is being pulled from the surviving star onto the black hole or neutron star that formed in the supernova, a process known to cause rapid changes in X-ray brightness.

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA’s Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they did not expect to find a population of supernova remnants, or the debris from these explosions, showing dramatic changes in their brightness. The new results were presented at the American Astronomical Society meeting in Pasadena, California, and published in The Astrophysical Journal.
The galaxy M83, located about 15 million light-years from Earth, is forming stars at a high rate. Researchers analyzed 14 years of Chandra data of the galaxy, spanning 2000 to 2014.
Using this extensive set of data, the researchers caught surprising variations in the X-ray brightness of sources previously identified as supernova remnants. The researchers expected supernova remnants older than a century or so to fade gradually in X-rays, but not change dramatically in brightness.
The team found that roughly half of the 22 X-ray sources associated with supernova remnants in their sample showed changes in X-ray brightness over the 14-year span of observations — a result that was completely unexpected.
“We knew that individual X-ray sources could vary dramatically,” said Andrea Prestwich, of the Catholic University of America who led the study. “But finding that so many supernova remnants were behaving this way was a real surprise. Something unusual is going on in these objects. Pinpointing the cause remains a challenge, as M83’s distance limits the detail we can observe.”
One of the 22 variable supernova remnants has a straightforward explanation: SN 1957D, the debris from a supernova first observed nearly 70 years ago, is ramming into material surrounding the explosion site, producing the observed X-ray flares. But this cannot explain the rest of the sample. There is no evidence to suggest that all 22 remnants were formed within the last century. Something else must be driving the variability.
The most likely explanation is that the team has uncovered a population of stellar survivors stars that lived through their partner’s destruction in a supernova explosion. In this scenario, each variable X-ray source began as a pair of massive stars orbiting each other. The more massive star collapsed and exploded as a supernova, leaving behind a black hole or ultra-dense neutron star. Its companion survived.

“It may be that this galaxy contains a collection of supernova remnants where one massive star survives the supernova and becomes locked into an orbit with a black hole or neutron star,” said co-author Michael McCollough of the Center for Astrophysics | Harvard & Smithsonian (CfA). “The neutron star or black hole can then start pulling material from the massive star’s surface.”
That infalling material is superheated by the intense gravitational pull, producing the X-rays Chandra detects. These types of systems, known as high-mass X-ray binaries (HMXBs), are among the most variable X-ray sources in the universe. Researchers say they may be the cause of the variations seen in M83’s supernova remnants.
Astronomers have known about HMXBs for decades, but the difference with this group in M83 is their connection to supernova remnants. Previously, only a handful of supernova remnants associated with HMXBs had been identified across observations of all galaxies. It is unprecedented to find more than 20 strong candidates in just one galaxy.
The authors found that the variable supernova remnants are in regions with higher concentrations of massive stars than in other parts of the galaxy, increasing the chances of a link between the remnants and HMXBs.
There is another possible explanation: Instead of pulling in material from a companion star, the black hole or neutron star may be recapturing some of the material blasted outward by the original explosion.
“This could be an example of cosmic recycling, where debris from the explosion falls back onto the very object the supernova created,” said co-author Roy Kilgard of Wesleyan University. “And it’s quite possible that both explanations are at play — different sources in our sample may have different origins.”
These results are not unique to M83. A follow-up study of the nearby star-forming galaxy M51 by Zoe Hoiland of Vassar College and Kilgard has uncovered a similar population of variable X-ray sources associated with supernova remnants, suggesting that such systems may be a feature of galaxies undergoing vigorous star formation.
This is a composite image of the galaxy M51 combining data from NASA’s Chandra X-ray Observatory (purple) with optical data (red, green and blue) taken with ground-based telescopes by a team of astrophotographers. A surprisingly high number of X-ray sources associated with supernova remnants in M51 show large changes in brightness, similar to the behavior seen in M83.

The Chandra data for M83 began with single observations in 2000 and 2001, followed by 10 observations from 2010 to 2011 and another observation in 2014.

NASA’s Chandra Discovers Possible Supernova Remnant in Galactic Center
Astronomers may have uncovered a new supernova remnant in a star-forming region near the center of the Milky Way galaxy using data from Chandra and XMM-Newton. If confirmed, this would be one of the closest supernova remnants to the supermassive black hole in the Galactic Center. This image shows the region where the evidence was found, which contains X-rays from Chandra and XMM-Newton, radio data from the MeerKAT telescope in South Africa, and an optical image from the Pan-STARRS telescopes in Hawaii.
Using data from NASA’s Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. A paper describing these new findings published in The Astrophysical Journal.
Supernova remnants are the expanding remains of exploded stars and provide elements – like iron, oxygen, and silicon – that are critical for the formation of planets and for life as we know it to form and flourish.
This new supernova remnant, if confirmed, would be one of the closest ever discovered to the supermassive black hole at the central region of the Milky Way galaxy, an exotic region crammed with massive stars, long threads of magnetic fields and dense clouds of gas orbiting rapidly around the Galactic Center.

A new composite image of this region contains X-rays from Chandra and ESA’s (European Space Agency’s) XMM-Newton mission (shown in blue) as well as radio data from the MeerKAT telescope (shown in red) in South Africa. These have been combined with an optical image from the Pan-STARRS telescopes in Hawaii (red, green, and blue). The plane of the galaxy runs horizontally from left to right in the image, and the central black hole is off to the left of the image.
The evidence for the new supernova remnant, located about 26,000 light-years from Earth, comes from X-ray data from Chandra and XMM-Newton. The X-ray data reveals a “blob” of X-ray emission that may come from the remains of a massive star that self-destructed as a supernova, buried within the larger cloud of expanding gas.
The location of this suspected supernova remnant in the image is labeled with a circle.
It is in a bubble of gas that has had electrons stripped away from hydrogen – called an “H II region” – surrounding a massive, young star. This bubble is a bright source of radio emission called Sagittarius C.
If this is indeed a supernova remnant, then it is expanding at about two million miles per hour and is at least about 1,700 years old. Previously, observations with NASA’s now-retired SOFIA (Stratospheric Observatory for Infrared Astronomy) mission had shown evidence for an expanding shell of gas surrounding Sagittarius C. This gave astronomers a hint that a stellar explosion had occurred in the same spot.
The long filaments seen in the radio image are caused by energetic particles travelling along magnetic fields that are mostly directed perpendicular to the plane of the galaxy.
The nuclear fusion engines of stars create elements from hydrogen and helium that were abundant at the beginning of the universe. When stars explode at the end of their lives as supernovae, they send these newly synthesized elements into interstellar space and provide material for the next generation of stars and planets.
The team of astronomers searched the X-ray data for signs of increased amounts of key elements in the remnant, which would have been caused by the stellar explosion blasting them into space. While they did not see an enhancement, this could imply that the stellar debris has already mixed with the surrounding gas.
An alternative explanation for the X-ray blob is that the hot gas comes from a collection of massive stars in the region. The authors of the recent study don’t think this explanation is likely, because the X-ray emission from the blob is more than ten times brighter than the X-ray emission of large, known stellar clusters with bright, massive stars.
An additional image shows data from NASA’s James Webb Space Telescope added to the X-ray and radio data. The light blue color represents infrared light from gas in the H II region, and the darker blue depicts X-rays from the supernova remnant candidate, on the right side of the image. X-rays near the center of the image are associated with the H II region, possibly caused by material blown away by massive stars that has heated gas to millions of degrees, producing X-rays.

Visual Description
This release features a composite image of colorful, overlapping clouds, which suggests to astronomers that a supernova remnant may be buried in gas near the center of our Milky Way galaxy.
Set against a backdrop packed with distant stars and other specks of light are two distinct, overlapping clouds. The larger, visually dominant cloud, is red and multifaceted. It has an irregular shape, and features patches of different textures, including pockets that resemble wispy smoke, tangles of faint red veins, and clear streaking lines. This large cloud of expanding gas represents radio data from the MeerKAT telescope in South Africa.
Overlapping with that red cloud is a cloudy blue blob representing X-ray data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. Astronomers suggest that this blue blob of X-ray emissions is the remains of a massive star destroyed by a supernova.

Listen to this audio excerpt from Elkin Norena, resident management officer, NASA’s Space Launch System Program:

NASA’s Elkin Norena has helped the agency launch more than a dozen space shuttle missions – that’s more than a dozen crews to low Earth orbit and more than a dozen historic missions. They were missions that helped build the International Space Station, that provided a final servicing mission to the Hubble Space Telescope, and that performed critical science experiments that improved life right here on Earth.
Today, he continues that work as the manager of the Resident Management Office for SLS at NASA’s Kennedy Space Center in Florida, helping launch America’s rocket – the SLS (Space Launch System) – and the Orion spacecraft with its international quartet of astronauts on the Artemis II mission to fly by the Moon and return home.

As resident manager, Norena provides onsite SLS support for NASA’s Exploration Ground Systems team that is responsible for preparing, stacking, testing, and launching SLS and Orion. He is also the eyes and ears for the SLS Program, providing an avenue of communications back to the program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
It is the continuation of a childhood dream to be part of space exploration.
“When I was a kid in New Jersey, I watched a space shuttle launch in class one day,” said Norena. “When I watched the power of launch and the brave astronauts going to explore, I knew I had to be a part of that one day. I wanted to become an astronaut.”
The dream to join the space program led the Colombia native to the University of Central Florida in Orlando, where he majored in computer engineering, just miles from the Space Coast and in view of space shuttle launches like the ones he once watched on TV.
When that clock ticks down to T-10 minutes, everybody’s just waiting. You wait for the automated system to kick in. You hold your breath and watch the clock go down to T-0. Then BOOM, launch happens, and you know it was all worth it.

Following college, he joined NASA contractor United Space Alliance at NASA Kennedy, and in 2008 he joined the NASA Kennedy team as a civil servant, working on the same spacecraft that inspired him to pursue the space program as a child.
“I started off in the Space Shuttle Program as an electrical engineer. Then I moved into the firing room for 17 different shuttle missions as a flight termination engineer. It was exciting to be part of all those missions and build the International Space Station,” Norena said.

Using those experiences, he became one of the original SLS team members. He was a part of the teams that successfully launched Artemis I and II and is now critical to the upcoming Artemis III mission.
Away from the launch pad, Norena’s hobbies orbit around his teenage daughters, participating in their activities. He also keeps a keen eye on space and is an avid astrophotographer.
“I love capturing the Milky Way! I’ve traveled to Utah, New Mexico, Arizona, and all across the western United States,” he said. “A great spot that’s closer for me is Dry Tortugas National Park beyond Key West.”
No matter how he explores space, Norena believes Artemis II is more than just a mission.
“This is historic. I grew up watching the shuttle missions, learning about Apollo, and wanting to be part of those Moon missions. We built the space station. The space shuttle explored space and technology on many levels,” he said. “Now, it’s our turn with Artemis to get back to the Moon, and this time to stay there. I’m excited to be part of the generation that does that.”
