Giant Supercluster Discovered in the Early Universe

   A international team of astronomers has discovered a gigantic structure in the early universe which existed about 2 billion years after the Big Bang. Hyperion, a galaxy proto-supercluster, is the largest and most massive structure discovered to date in the early universe.
   The team which includes scientists from the Istituto Nazionale di Astrofisica (INAF) in Bologna, Italy, and the University of California, Davis, used the VIMOS instrument on ESO's Very large Telescope in Paranal, Chile to identify the galaxies.
   Hyperion is estimated to have a combined mass of over 1 million billion times that of the sun. This enormous mass is comparable to the largest structures observed in the universe today, making this discovery very surprising for many astronomers.
   Found in the constellation of Sextans (the Sextant), the team noticed that Hyperion has a very complex structure. This includes seven high-density regions connected by filaments of galaxies. These regions differ to superclusters found today as their masses are distributed much more uniformly in a series of connected blobs with loose associations of galaxies.
