NGC 1132

NGC 1132 is an elliptical galaxy located in the constellation Eridanus.[1] The galaxy was discovered by John Herschel on November 23, 1827.[2] It is located at a distance of about 318 million light-years away from Earth.[3]

NGC 1132 and nearby small galaxies are known as a "fossil group" that resulted from the merger of a group of galaxies.[1] It is notable for being the prototype example of the class of fossil galaxy groups.[4] The identification as a fossil group was made in 1999.[5] This group contains an enormous amount of dark matter and a large amount of hot gas that emits X-ray radiation.[6] The galaxy is surrounded by thousands of globular star clusters.[7]
