Chandra Observatory reveals surprising X-ray brightness variations in supernova remnants of galaxy M83
Summary
NASA's Chandra X-ray Observatory data spanning over 14 years reveals that more than 20 previously identified supernova remnants in the galaxy Messier 83 (M83) are varying unexpectedly in X-ray brightness. These variable sources represent roughly half of the X-ray sources associated with supernova remnants in the study sample, challenging previous assumptions about the stability of these stellar remnants.

· 3 pulledBy analyzing data from NASA's Chandra X-ray Observatory that span over 14 years, researchers found over 20 previously identified supernova remnants — remains from stars that exploded — that vary unexpectedly in X-ray brightness in Messier 83 (M83).
These represent roughly half of the X-ray sources associated with supernova remnants in their sample in M83.
This graphic shows two of the X-ray sources in a nearby galaxy that are changing their brightness in surprising ways as described in our latest press release.
