"Wow Signal" was a strong, narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977 while working on a SETI 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. It lasted for 72 seconds, the full duration Big Ear observed it, and has not been detected again, or not reported to the public. It has been the focus of attention in the mainstream media when talking about SETI results. Amazed at how closely the signal matched the expected signature of an interstellar signal in the antenna used, Ehman circled the signal on the computer printout and wrote the comment "Wow!" on its side. This comment became the name of the signal. On the 35th anniversary of the Wow! signal, Arecibo Observatory beamed a response from humanity, containing 10,000 Twitter messages, in the direction from which the signal originated. Read more....

Mysterious Wow! Signal From Space Deciphered, Says Astronomer   Epoch Times - January 14, 2016
For almost 40 years, astronomers have wondered whether an anomalous 72-second radio signal from space may have been an attempt by extraterrestrials to contact us. Was the sound from comet? In 2017 and 2018 when the same comets again enter the same region of space, an analysis of their hydrogen signals could confirm a new theory.

Was the Wow Signal our first detection of extraterrestrials? It might have been, but no scientist would make such a claim. Scientific experiment is inherently skeptical. This isn't just a sour attitude; it's the only way to avoid routinely fooling yourself. Until and unless the cosmic beep measured in Ohio is found, the Wow Signal will remain a What Signal.

The Wow Signal came from the direction of Sagittarius.
