The Spiderweb Galaxy (PGC 2826829, MRC 1138-262) is an irregular galaxy with a redshift of 2.156, which is 10.6 billion light years away. It has been imaged by the Hubble Space Telescope on 12 October 2006.[2] It is formed from dozens of smaller galaxies that were seen in the process of merging through mutual gravitational attraction.
