Discovered in 2006, XMMXCS 2215-1738 is one of the most distant galaxy clusters known. It is embedded in intergalactic gas that has a temperature of 10 million degrees. The estimated mass of the cluster is 500 trillion solar masses, most coming from dark matter. The cluster was discovered and studied using the XMM-Newton and Keck Telescopes. The cluster is surprisingly large and evolved for a cluster that existed when the universe was only 3 billion years old.
Led by University of Sussex researchers, part of the XMM Cluster Survey (XCS) used X-ray Multi Mirror (XMM) Newton satellite to find it, Keck Telescope to determine distance, and used the Hubble Space Telescope to further image it.
It contains hundreds of reddish galaxys surrounded by x-ray-emitting gas.

The galaxy is called XMMXCS 2215-1734 in many references, with some news sources listing both names. The source of the naming contradiction between XMMXCS 2215-1734 and XMMXCS 2215-1738 is not known. However, XMMXCS 2215-1738 seems to be the more accurate.
