Elemental Image Of Exploded Star
Upper left: Broadband X-ray image of Cassiopeia A (Cas A) Upper right: Image made by X-Rays from silicon ions. Lower left: Image made by X rays from calcium ions. Lower right: Image made by X rays from iron ions. All images are 8.5 arc minutes on a side (corresponding to 28.2 light years at a distance of 11,000 light years).
