Heart of Andromeda
Andromeda is a large spiral galaxy, a neighbor to our Milky Way. Andromeda, in Greek mythology, was the daughter of King Cepheus and Queen Cassiopeia. She was chained to a rock in the sea as a sacrifice to the monster Cetus. But what lies in her heart? A new observation by the Chandra X-ray Observatory helps answer this question. The image above shows an X-ray image of the center of Andromeda, and shows the remnants of s history of stellar explosions. The points of lights are X-ray binaries, the remnants of dead stars. The diffuse emission shown above also represents the accumulated hot gas produced by supernova explosions. Evidently the heart of Andromeda is a heart in turmoil.
