The Wow! signal was a strong, narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977 while working on a SETI (Search for Extraterrestrial Intelligence) project at the Big Ear radio telescope of the Ohio State University. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin.
