Edmonds<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA\u2019s 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.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<p>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 \u2014 a result that was completely unexpected.<\/p>\n<p>\u201cWe knew that individual X-ray sources could vary dramatically,\u201d said Andrea Prestwich, of the Catholic University of America who led the study. \u201cBut 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\u2019s distance limits the detail we can observe.\u201d<\/p>\n<p>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.<\/p>\n<p>The most likely explanation is that the team has uncovered a population of stellar survivors stars that lived through their partner\u2019s 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.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=3000&#038;h=3000&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"3000\" height=\"3000\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=3000&#038;h=3000&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"A full field composite image of M83 with X-rays from Chandra (red, green, and blue) and optical light data from Hubble (red, green, and blue).\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" loading=\"lazy\" srcset=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=3000&#038;h=3000&#038;fit=crop&#038;crop=faces%2Cfocalpoint 3000w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=150&#038;h=150&#038;fit=crop&#038;crop=faces%2Cfocalpoint 150w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=300&#038;h=300&#038;fit=crop&#038;crop=faces%2Cfocalpoint 300w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=768&#038;h=768&#038;fit=crop&#038;crop=faces%2Cfocalpoint 768w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=1024&#038;h=1024&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1024w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=1536&#038;h=1536&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1536w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=2048&#038;h=2048&#038;fit=crop&#038;crop=faces%2Cfocalpoint 2048w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=50&#038;h=50&#038;fit=crop&#038;crop=faces%2Cfocalpoint 50w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=100&#038;h=100&#038;fit=crop&#038;crop=faces%2Cfocalpoint 100w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=200&#038;h=200&#038;fit=crop&#038;crop=faces%2Cfocalpoint 200w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=400&#038;h=400&#038;fit=crop&#038;crop=faces%2Cfocalpoint 400w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=600&#038;h=600&#038;fit=crop&#038;crop=faces%2Cfocalpoint 600w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=900&#038;h=900&#038;fit=crop&#038;crop=faces%2Cfocalpoint 900w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=1200&#038;h=1200&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1200w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83.jpg?w=2000&#038;h=2000&#038;fit=crop&#038;crop=faces%2Cfocalpoint 2000w\" sizes=\"auto, (max-width: 3000px) 100vw, 3000px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\">Galaxy M83 in X-ray and Optical Light.<\/div>\n<div class=\"hds-credits\">X-ray: NASA\/CXC\/SAO; Optical: NASA\/ESA\/AURA\/STScI, Hubble Heritage Team, W.

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\u2019s supernova remnants.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<p>\u201cThis could be an example of cosmic recycling, where debris from the explosion falls back onto the very object the supernova created,\u201d said co-author Roy Kilgard of Wesleyan University. \u201cAnd it\u2019s quite possible that both explanations are at play \u2014 different sources in our sample may have different origins.\u201d<\/p>\n<p>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.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83_m51.jpg?w=2400&#038;h=1825&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"2400\" height=\"1825\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/chandra\/2026\/m83_m51.jpg?w=2400&#038;h=1825&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"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.

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.<\/p>\n<p>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.<\/p>\n<p>Over a 14-year period from 2000 to 2014, astronomers pointed NASA\u2019s 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.<\/p>\n<p>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.<\/p>\n<p>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\u2019s 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.<\/p>\n<p><a
