Wow! Signal.

did-you-kno:

The Wow! signal was a strong narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977 while searching for Aliens. It lasted for the full 72-second duration that Big Ear observed it, but has not been detected again.

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.
