The Wow! signal was a strong narrowband radio signal detected by Jerry R. Ehman on August 15, 1977, while working on a SETI project at the Big Ear radio telescope of The Ohio State University then located at Ohio Wesleyan University's Perkins Observatory, Delaware, Ohio.[1] The signal bore expected hallmarks of potential non-terrestrial and non-Solar System origin. It lasted for the full 72-second duration that Big Ear observed it, but has not been detected again. The signal has been the subject of significant media attention.
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.[1]
But was it? More than three decades later, the Wow Signal, as it has come to be known to SETI researchers, remains both the first and best potential evidence of communication from extraterrestrials, and one of the most perplexing mysteries in science. Over the years, Ehman and colleagues worked to rule out other explanations—such as satellites, aircraft or ground-based transmitters on Earth. But by the same token, researchers have yet to prove that it actually is message from space. “It’s an open question.” Ehman told the Columbus Dispatch in 2010. Or as the late science-fiction author Arthur C. Clarke once put it in a 1997 interview with New Scientist magazine, “God only knows what it was.”
To grasp the significance of the Wow Signal, it helps to understand what Ehman and his colleagues were looking for. Back in the early 1960s, Cornell physicists Philip Morrison and Guiseppe Cocconi had tried to figure out how a distant extraterrestrial civilization, if one existed, might try to contact others in the universe. First, they hypothesized, aliens would use a radio signal, since such transmissions require relatively little energy to generate and can travel huge distances across space. Second, they assumed that the aliens would be smart enough to pick a message that other intelligent species might understand, even if they spoke a very different language. Chemicals, they noted, emit distinctive electromagnetic frequencies, or signatures, which is how astronomers can determine the composition of distant planets and stars from their light. Since hydrogen, the most common element in the universe, emits a signal with a frequency of 1420 megahertz, they reasoned that aliens might send out a signal that mimicked it.

Apparently NatGeo has a new show called "Chasing U.F.O's". That will be premiering next week, and they are focusing their first episode on the WOW signal.

Here you can find out how to send your own tweet into space, and see what others are saying.

And here is the WOW signal location. For those that it might interest.
Even though I dont have twitter I think its interesting nonetheless.
Peace, NRE.
