The Spiderweb Galaxy (PGC 2826829, MRC 1138-262) is an irregular galaxy located in the Hydra constellation, with a redshift of 2.156, which is 10.6 billion light years from the Milky Way.[2] It has been imaged by the Hubble Space Telescope on 12 October 2006.[3] It was thoroughly studied through radio astronomy, but it was not until the Hubble Telescope took a mosaic of photographs from May 17 to May 22, 2005, that its true nature became known.[4] This was documented for the first time on October 10, 2006, in The Astrophysical Journal Letters, volume 650, number 1.[2] The photography was carried out using an advanced camera for surveys by a team led by George K. Miley of the Netherlands' Leiden Observatory.
