Chandra Reveals the Elementary Nature of Cassiopeia A, Cas A.

A new Chandra image shows the location of several elements produced by the explosion of a massive star. Cassiopeia A is a well-known supernova remnant located about 11,000 light years from Earth. Supernova remnants and the elements they produce are very hot — millions of degrees — and glow strongly in X-ray light. Chandra's sharp X-ray vision allows scientists to determine both the amount and location of these crucial elements objects like Cas A produce.
