3-D Map of Cassiopeia A Supernova Remnant

Caption

This composite image shows two perspectives of a three-dimensional reconstruction of the Cassiopeia A supernova remnant. This new 3-D map provides the first detailed look at the distribution of stellar debris following a supernova explosion. Such 3-D reconstructions encode important information for astronomers about how massive stars actually explode. The blue-to-red colors correspond to the varying speed of the emitting gas along our line of sight. The background is a Hubble Space Telescope composite image of the supernova remnant.
