Alien Lore. No.125 : The Wow Signal

Thanks to Jeff Clinton for pointing this one out. I'd heard of the Wow signal, but never read about it.

The Wow! signal was a narrowband (and surprisingly robust) 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 Ohio State University. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for 72 seconds.

The Wow signal has often been considered the most promising, or the most likely, signal SETI has studied to date.

Dr. Ehman circled the signal on the computer printout and wrote the comment "Wow!" on its side. . .ergo the name by which it is still known.
