A galaxy cluster was discovered by this 10-meter wide South Pole Telescope, which is located at NSF's Amundsen-Scott South Pole Station in Antarctica and funded by NSF's Office of Polar Programs. NSF manages the U.S. Antarctic Program, through which it coordinates all U.S. research and required logistical support on the continent as well as aboard ships in the Southern Ocean.

Galaxy clusters, which are among the largest objects in the universe, contain enough hot gas to create detectable "shadows" in the light left over from the Big Bang, which also is known as the cosmic microwave background radiation. The cluster discovered by the South Pole Telescope (SPT) has been dubbed the "Phoenix Cluster" not only because it is located in the constellation of the Phoenix but also because of its remarkable properties. The Phoenix Cluster and its central galaxy and super-massive black hole are already among the most massive known objects of their type.
