is one of the most massive galaxy clusters ever found in the early universe. It is thought to be 7 billion light years away. It was discovered at the [[Astronomy:South Pole Telescope|South Pole Telescope]] in 2008 by the Sunyaev-Zel'dovich-Effect. The cluster has a redshift of z=1.067.  Follow-up studies using the [[Astronomy:Spitzer Space Telescope|Spitzer]], [[Astronomy:Chandra X-ray Observatory|Chandra]], and optical telescopes allowed to identify cluster members and to measure the redshift.  Using the velocity dispersion, the cluster mass has been estimated to 10<sup>15</sup> solar masses.
