Largest galaxy proto-supercluster found - space science news

An international team of astronomers, using the VIMOS instrument of ESO’s Very Large Telescope, has found an enormous proto-supercluster forming in the early universe, 2.3 billion after the Big Bang. Its mass has been calculated to be more than one million billion times that of the sun. Unlike other superclusters and the supercluster of which our galaxy, the Milky Way, is part, mass is evenly distributed throughout the newly found proto-supercluster, which is due its relatively young age. These observations give more insight into the formation of the universe’s superclusters.
