: This image shows the Perkins Observatory near Ohio Wesleyan University in Delaware, Ohio. Near the observatory is the famous "Big Ear" radio telescope, which had a collecting area of 340 by 70 feet (104 by 21 meters). The Ohio Sky Survey recorded here between 1965 and 1972 was the most accurate, reliable, and complete mapping of cosmic radio signals (the "radio sky") for many years. This observatory conducted a 24-year continuous search for evidence of extraterrestrial intelligence, during which the famous "Wow!" signal was received in 1977. View on Ohio Memory.
