Oak Ridge Observatory, Massachusetts

Until its closure in 2005, this astronomical observatory was operated by Harvard University and the Smithsonian Institution. It was located in the hills above the town of Harvard, outside of Boston. Facilities included reflector telescopes, and several crumbling historic astronomical instruments. Also on the site was an 84-foot diameter radio telescope used by SETI's BETA program - the Search for Extra Terrestrial Intelligence's Billion Channel Extra-Terrestrial Assay - where 250 million channels could be scanned at once to search for "intelligent" radio signals from outer space. This portion of the observatory was supported by the Planetary Society, based in Pasadena, California. In 2007, a decision was made to dismantle the radio telescope, due to severe storm damage. Currently a portion of the observatory is being used as part of a larger automated Optical SETI program.
