XMMXCS 2215-1738 is a galaxy cluster that lies 10 billion light-years away, or redshift z=1.45 . It was discovered by the XMM Cluster Survey in 2006.

XMMXCS 2215-1738 is the most distant galaxy cluster discovered as of June 2006. 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. 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.
