Astronomers Find Record-Setting Galaxy Cluster

A massive so-called galaxy cluster, one of the largest structures in the universe, has been discovered about 5.7 billion light years from Earth and credited with setting several important new cosmic records, U.S.-based researchers said on Wednesday.

The Harvard-Smithsonian Center for Astrophysics said in a news release that observations of the cluster, which has shown a prodigious rate of star formation, may force astronomers to rethink how such colossal structures and galaxies that inhabit them evolve over time.

Known officially by an alphabet soup of numbers and letters as SPT-CLJ2344-4243, the cluster has been nicknamed "Phoenix," after the mythological bird that rose from the dead.
