NGC 1132

NGC 1132 and nearby small galaxies are known as a "fossil group" that resulted from the merger of a group of galaxies. It is notable for being the prototype example of the class of fossil galaxy groups. The identification as a fossil group was made in 1999. This group contains an enormous amount of dark matter and a large amount of hot gas that emits X-ray radiation. The galaxy is surrounded by thousands of globular star clusters.
