Now a multi-institution team led by MIT researchers has identified a galaxy cluster seven billion light-years away that dwarfs most known clusters, churning out a dazzling 740 new stars per year in the central galaxy. The galaxy cluster is among the most massive and most luminous in the universe. While scientists have formally catalogued the cluster by the name SPT-CLJ2344-4243, the MIT-led group has a more informal moniker: the Phoenix cluster, named after the constellation in which it resides... 'Central galaxies have typically been referred to as 'red and dead' -- just a bunch of old stars orbiting a massive black hole, and there's nothing new happening,' McDonald says. 'But the central galaxy in this cluster has somehow come to life, and is giving birth to prodigious numbers of new stars.'
