The Gargantuan Galaxy NGC 1132 - Annotated
This Hubble image shows the giant elliptical galaxy NGC 1132 with annotations showing some of the surrounding dwarf galaxies (in red) and some of its numerous globular clusters (in blue).
NGC 1132, together with the small dwarf galaxies surrounding it, are dubbed a fossil group as they are most likely the remains of a group of galaxies that merged together in the recent past.
NGC 1132 is surrounded by thousands of ancient globular clusters, swarming around the galaxy like bees around a hive. These globular clusters are likely to be the survivors of the disruption of their cannibalised parent galaxies that have been eaten by NGC 1132 and may reveal its merger history. In the background, there is a stunning tapestry of numerous galaxies that are much further away.
