remnants of a supernova

The destructive results of a powerful supernova explosion reveal themselves in a delicate tapestry of X-ray light, as seen in this image from NASA’s Chandra X-Ray Observatory and the European Space Agency's XMM-Newton. This image shows Puppis A, the remains of a supernova that would have been witnessed on Earth about 3,700 years ago. Low-energy X-rays are shown in red, medium-energy X-rays are in green and high energy X-rays are colored blue. Image credit: NASA/CXC/IAFE/G.Dubner et al & ESA/XMM-Newton
