" The "Wow!" source radio emission entered the receiver of the Big Ear radio telescope at about 11 : 16 pm Eastern Daylight Savings Time on August 15, 1977. The Wow! signal was a strong narrowband radio signal detected by Dr. Jerry R.

The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for a total of 72 seconds, the full duration Big Ear observed it, but has not been detected again. Much attention has been focused on it in the media when talking about SETI results. Both the length of the Wow! signal, 72 seconds, and its shape corresponds to an extraterrestrial origin but its source remains unexplained. The region of the sky in which the signal was heard, lies in the constellation Sagittarius, roughly 2.5 degrees south of the fifth-magnitude star Chi-1 Sagittarii. Since then, its never been heard again. " BigEar " Destroyed 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 <b>...</b>
