Gargantuan galaxy NGC 1132 -- a cosmic fossil?

The NASA/ESA Hubble Space Telescope has captured a new image of the galaxy NGC 1132 which is, most likely, a cosmic fossil -- the aftermath of an enormous multi-galactic pile-up, where the carnage of collision after collision has built up a brilliant but fuzzy giant elliptical galaxy far outshining typical galaxies. 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. In this Hubble image, NGC 1132 is seen 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. Credit: NASA, ESA, M. West (ESO, Chile)
