In late 1997, after almost 40 years of operation, the Ohio State University Radio Observatory, with its "Big Ear" radio telescope, ceased operation. The land on which the observatory was sitting (owned by the Ohio Wesleyan University, Delaware, Ohio) was sold by them in 1983 to land developers who later claimed their rights to develop the land. The telescope was destroyed in early 1998. An adjacent 9-hole golf course was expanded into 18 holes and about 400 homes were planned for construction on the nearby land owned by those developers.
This website is meant to serve as a memorial to that unique radio telescope and to the discoveries made with that instrument.
This site is dedicated to the history of the Big Ear Radio Observatory. The observatory, located near Cleveland Ohio, was demolished in 1998 but the site lives on. Researchers will find a history of the project, technical information about the observatory and a few brief details about some of the staff that worked there. Primary documents only include articles from the Cleveland Plain Dealer.
