A composite image of the nearby galaxy Messier 83, and short timelapse videos of two curious supernova remnants hidden inside.

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.

Hall, T.Heuberger, J.Jacks, P.Kent, Br.Meyers, W.Ostling, N.Puig, T.Schaeffer, F.Schöfbänker, M.Vasilev

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.

Visual Description

This release features a composite image of the nearby galaxy Messier 83, and short timelapse videos of two curious supernova remnants hidden inside.

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.

NASA’s SpaceX CRS-34 Dragon Returns Packed with Space Station Science

NASA - Breaking News - Mon, 06/15/2026 - 1:30pm

Scientists await a big splash in the Pacific Ocean as one of the most research-packed Dragon spacecraft to date returns, completing the 34th SpaceX commercial resupply mission to the International Space Station for NASA. Biological and materials samples, along with tested hardware, are heading back to research teams on Earth for further analysis, advancing NASA’s work to prepare humans for exploration beyond low Earth orbit and to deliver benefits back home.

Tiny cells, huge health insights NASA astronaut Jessica Meir prepares samples in the Life Sciences Glovebox to study how weightlessness affects crew blood clotting and immune function for the Megakaryocyte Flying-One investigation.NASA

Some samples returning are for NASA’s Hematopoietic Stem Cell Expansion in Space: Pathfinder Investigation (InSPA-StemCellEX-H2), which seeks to use the microgravity environment to scale up the production of stems cells. On Earth, lab-produced blood stem cells lose their ability to form different cell types, like red and white blood cells that are critical to treating patients with certain blood diseases and cancers. In microgravity, researchers believe this ability will be better preserved while also growing these stem cells in greater numbers. The returning samples will undergo further analysis to determine if space-based efforts produce larger quantities of enhanced stem cells suitable for clinical use.

The team behind NASA’s Streptococcus pneumoniae (Spn) Infection of Cardiac Tissue (MVP Cell-09) experiment is awaiting the return of stem cell-derived heart tissues that were intentionally infected with a pneumonia-causing bacterium as part of ongoing microgravity research. Pneumonia increases the risk of heart disease, which is not fully understood. Because bacteria tend to become more active and virulent in microgravity, this experiment could amplify their effects, making it possible to detect cellular responses that cannot be observed on Earth.

NASA’s Megakaryocyte Flying-One (MeF1) samples are returning to Earth to help understand how large cells found in bone marrow, known as megakaryocytes, and the platelets they produce adapt to spaceflight. Megakaryocytes and platelets play important roles in the formation of blood clots and immune responses. The returning samples, including those taken from astronauts, could show us how the human immune system reacts aboard the space station and help prepare for future exploration missions.

Driving design enhancements NASA astronaut Mike Fincke and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui work on hardware for the Zero Boil-Off Tank investigation.NASA

Many spacecraft use cryogenic fuels for propulsion, but temperature swings in space can cause these extremely cold fuels to slowly evaporate and escape their tank, reducing fuel efficiency and complicating mission planning. NASA’s Zero Boil-Off Tank Noncondensables (ZBOT-NC) investigation aboard station studies how gases that do not condense into liquids at cold temperatures affect pressure control and fluid behaviors in propellant tanks. Hardware returning aboard Dragon, including drives containing fluid-physics data, could help validate models and contribute to the design of more efficient cryogenic fuel storage systems for long-duration missions.

Semiconductor research samples as part of NASA’s In-Space Production of Semimetal-Semiconductor Composite Bulk Crystals in Microgravity (SUBSA-InSPA-SSCug) investigation are returning to Earth for further analysis. This study manufactured semimetal-semiconductor composite alloy crystals in space, which have applications in many electronics, including sensors and lasers. Researchers believe microgravity could enable the production of significantly greater and higher-quality crystals, supporting the development of next-generation semiconductor technologies.

Innovative medical research mix Stem cells grown along a DNA-inspired nanomaterial on space station as part of DNA Nano Therapeutics-Mission 2, a percussor to DNA Nano Therapeutics-3.University of Connecticut

NASA’s DNA Nano Therapeutics-3 research team will receive tiny, space-assembled DNA-inspired materials that are combined with medicines to create active cancer treatments. Producing these treatments in microgravity can improve how well they perform in the body. This research could improve patient outcomes by helping therapies reach tumors more effectively, stay in the body longer, and improve medicine release.

Tissue models of the brain, heart, liver, and kidney that were tested with novel RNA-based medicines as part of NASA’s InSPA-Sachi Nanoligomer investigation are also returning. Microgravity can accelerate aging and disease processes, giving researchers a unique environment to better observe how well these new drugs work on different organs ahead of clinical trials.

The left image shows various wood-derived products of different shapes, and the right image shows a sample of this same material in a laboratory setting on Earth. These products may have applications in the medical field by providing scaffolding for patients with fragile bones.GreenBone Ortho

Samples from ESA’s (European Space Agency) Green Bone investigation are returning to Earth to help understand how bone cells grow and develop on a new scaffold made from wood. Designed to mimic real bone, this scaffold was tested in microgravity to understand its ability to heal defects and fractures. Because living in microgravity simulates conditions like osteoporosis, a skeletal disorder which affects millions of people worldwide, the results could help treat patients with these fragile bone conditions. 

NASA’s 3D Bone Marrow Analog research team will analyze the returning 3D-printed tissues that mimic parts of the bone marrow. Spaceflight can cause aging-like changes, including bone and muscle loss. To investigate potential countermeasures, these tissue models were exposed to small vibrations aboard the space station to simulate exercise. After the samples return to Earth, researchers will measure bone-like mineral formations and observe cellular and genetic changes. Findings from this investigation could help develop new strategies to maintain astronaut bone and muscle health during future long-duration missions.

In the United States, more than 900,000 knee cartilage injuries occur annually, with many requiring surgery. NASA’s InSPA-Auxilium Bioprinter-Cell Printing is investigating how to treat these injuries and is returning 3D-printed cartilage tissue samples from space station. This investigation uses the orbiting laboratory’s unique microgravity environment to bioprint cartilage tissues with more evenly distributed cells compared to those printed on Earth. The results could help produce higher-quality cartilage prints to treat joint injuries.

NASA astronaut Anil Menon will be available for limited media interviews beginning at 9 a.m. EDT Monday, June 22, to discuss his upcoming mission to the International Space Station as part of Expeditions 74/75.

The virtual interviews will take place from the Gagarin Cosmonaut Training Center in Star City, Russia, and will stream live on the agency’s YouTube channel.

Media interested in participating must submit a request to the newsroom at NASA’s Johnson Space Center in Houston no later than 5 p.m. Wednesday, June 17, by emailing jsccommu@mail.nasa.gov. A copy of NASA’s media accreditation policy is online.

Menon is scheduled to launch to the space station Tuesday, July 14, from the Baikonur Cosmodrome in Kazakhstan aboard the Roscosmos Soyuz MS-29 spacecraft with Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina. The trio will spend about eight months aboard the orbiting laboratory before returning to Earth in spring 2027.

During his expedition, Menon will conduct scientific investigations and technology demonstrations to help humans prepare for future exploration missions to the Moon and Mars, and to provide benefits on Earth. Among the hundreds of experiments planned during his mission, he will participate in studies to better understand astronaut vein structure, blood flow, and blood composition in microgravity. He also will test producing intravenous fluids using the space station’s potable water.

The Soyuz MS-29 mission will be his first spaceflight after he was selected as part of NASA’s 2021 astronaut class. A native of Minneapolis, Menon is an emergency medicine physician, mechanical engineer, and colonel in the United States Space Force. He also has served as an expedition flight surgeon supporting the agency’s crew members aboard the space station.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.
