SPACE-US-SUPERNOVA
This NASA image from NASA’s Chandra X-Ray Observatory and the European Space Agency's XMM-Newton, released on September 10, 2014 shows the remains of a supernova that would have been witnessed on Earth about 3,700 years ago. The remnant is called Puppis A, and is around 7,000 light years away and about 10 light years across. This image provides the most complete and detailed X-ray view of Puppis A ever obtained, made by combining a mosaic of different Chandra and XMM-Newton observations. Low-energy X-rays are shown in red, medium-energy X-rays are in green and high energy X-rays are colored blue.
These observations act as a probe of the gas surrounding Puppis A, known as the interstellar medium. The complex appearance of the remnant shows that Puppis A is expanding into an interstellar medium that probably has a knotty structure. Supernova explosions forge the heavy elements that can provide the raw material from which future generations of stars and planets will form.
