Professor Bob Kirshner celebrates the successful casting of the third of seven mirrors for the Giant Magellan Telescope which the Dean of FAS, Michael Smith, has just approved as a major funding-raising focus for the University. The casts are made under the University of Arizona football stadium overseen by the Steward Observatory there.
Cambridge, MA - Scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) and their colleagues at the Heidelberg Institute for Theoretical Studies (HITS) have invented a new computational approach that can accurately follow the birth and evolution of thousands of galaxies over billions of years. For the first time it is now possible to build a universe from scratch that brims with galaxies like we observe around us.
Cambridge, MA - Astronomers have found an extraordinary galaxy cluster, one of the largest objects in the universe, that is breaking several important cosmic records. Observations of the Phoenix cluster with NASA's Chandra X-ray Observatory, the National Science Foundation'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.
