Harvard-Smithsonian Center for Astrophysics (CfA)
Harvard-Smithsonian Center for Astrophysics (CfA) is a joint collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory, located in Cambridge, Massachusetts. The Center's research mission is to study the origin, evolution, and ultimate fate of the Universe, and includes searches for extrasolar planets and circumstellar disks. In 1999, it independently announced the discovery of the two outer planets in the Upsilon Andromedae system. Among the facilities operated by the Center are the Multiple Mirror Telescope (MMT) and the Fred Lawrence Whipple Observatory.
