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.[1]

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.[2]
