The Ohio State University Radio Observatory was a Kraus-type (after its inventor John D. Kraus) radio telescope located on the grounds of the Perkins Observatory at Ohio Wesleyan University in Delaware, Ohio from 1963 to 1998. Known as Big Ear, the observatory was part of Ohio State University's Search for Extraterrestrial Intelligence (SETI) project. The telescope was designed by John D. Kraus. Construction of the Big Ear began in 1956 and was completed in 1961, and it was finally turned on for the first time in 1963. The main reflector of Big Ear—The Flat Reflector—measured approximately 103 meters by 33 meters, giving it the sensitivity equivalent to a circular dish measuring nearly 53 meters in diameter.The observatory completed the Ohio Sky Survey in 1971, and from 1973–1995, Big Ear was used to search for extraterrestrial radio signals, making it the longest running SETI project in history. In 1977, the Big Ear received the Wow! signal. The observatory was disassembled in 1998 when developers purchased the site from the university and used the land to expand a nearby golf course.

In Delaware, Ohio, two other railroads, the Chesapeake & Ohio Railway and Pennsylvania Railroad had stations with passenger service. Yet, the Big Four Depot was the far busier station.In 1944, in the latter years of World War II there were several trains a day. In each direction (north and south) four trains on the Cincinnati-Columbus-Cleveland corridor: three daily and one daily except Sunday train; additionally, there was a Cincinnati-Cleveland train making daily stops at the station.By the early 1960s, service declined to a Cincinnati-Columbus-Cleveland train, the Night Special. The train ceased stopping at the station on November 19, 1965. The station continued for few years as a freight depot.The building is extant. Preservationists and other community activists have sought protect and renovate the building. In 2018 the building was added to Preservation Ohio's list of most endangered historic sites. It was listed on the National Register of Historic Places in 2022. The city of Delaware had other stations, run by the Pennsylvania Railroad and Chesapeake and Ohio Railway, respectively.
