    About Oak Ridge:
    The Oak Ridge Observatory, in Harvard, Massachusetts, formerly operated the largest optical telescope east of Texas in the U.S. Owned by Harvard University, it was operated by the Smithsonian Astrophysical Observatory (SAO), part of the Harvard-Smithsonian Center for Astrophysics (CfA) until August 19, 2005.

    In 2016, Nola Taylor Redd wrote a nice piece for SPACE.COM about the closed-down site: Old Eyes on the Sky: Touring Harvard's Shuttered Oak Ridge Observatory

    Optical Research:
    The Wyeth 61-inch reflector carried out research on stellar radial velocities and the motions of comets and asteroids.

    Radio Research:
    An 84-foot steerable radio telescope was used in Project BETA, a search for extraterrestrial intelligence.

    Harvard University's Optical SETI program continues at Oak Ridge
    See the Harvard SETI Homepage for more information.
