Chandra X-ray Image of NGC 1132
This image of elliptical galaxy NGC 1132 and its surrounding region shows the X-ray glow from hot, diffuse gas detected by Chandra. Astronomers have dubbed NGC 1132 a "fossil group" because it contains an enormous amount of dark matter, comparable to the dark matter found in an entire group of galaxies. Also, the large amount of hot gas detected by Chandra is usually found for groups of galaxies, rather than a single galaxy. On the right, the white box represents the Hubble Space Telescope's field of view.

Hubble Optical Image of NGC 1132
The elliptical galaxy NGC 1132 reveals the final result of what may have been a group of galaxies that merged together in the recent past. Another possibility is that the galaxy formed in isolation as a "lone wolf" in a universe ablaze with galaxy groups and clusters. This image of NGC 1132 was taken with Hubble's Advanced Camera for Surveys. Data obtained in 2005 and 2006 through green and near-infrared filters were used in the composite. NGC 1132 is located approximately 318 million light-years away in the constellation Eridanus, the River. More information at Hubble
