Chandra Reveals the Elementary Nature of Cassiopeia A
This image from NASA’s Chandra X-ray Observatory shows the location of different elements in the Cassiopeia A supernova remnant including silicon (red), sulfur (yellow), calcium (green) and iron (purple). Each of these elements produces X-rays within narrow energy ranges, allowing maps of their location to be created. The blast wave from the explosion is seen as the blue outer ring. Astronomers study supernova remnants to better understand how stars produce and then disseminate many of the elements on Earth and in the cosmos at large.
