PHOENIX CLUSTER SETS RECORD PACE FOR CREATING STARS

Media Telecon:


Aug. 15, 2012 (1:00 p.m. Eastern)

Astronomers have found an extraordinary galaxy cluster—one of the largest objects in the Universe—that is breaking several important cosmic records. Observations of this cluster, known as the Phoenix Cluster, with NASA's Chandra X-ray Observatory, the NSF's South Pole Telescope and eight other world-class observatories, may force astronomers to rethink how these colossal structures, and the galaxies that inhabit them, evolve.
