2XMM J083026+524133 (2XMM J0830) is a very large galaxy cluster that lies 7.7 billion light-years away. It was discovered by ESA's XMM Newton and the Large Binocular Telescope (LBT) in Arizona in 2008.
As of 2008, it was the largest known galaxy cluster at red shift z ≧ 1, weighing in at an estimated 1015 solar masses. However, galaxy cluster XMMXCS 2215-1738 is several billion light years farther away.
