Is Anybody Out There?

On August 15th 1977 a strange signal from the constellation Sagittarius was received by the Big Ear radio telescope. 

The signal known as the ‘Wow!’ signal reached an intensity up to 30 times higher than the usual signals detected and it had a duration of 72 seconds. The name comes from the side note written by astronomer Jerry R. Ehman at the moment the signal was discovered.

Ehman was a collaborator at the SETI project, a project which was set up in 1969 by NASA to search for extraterrestrial intelligence. The Wow! signal is among all the strange signals received up until now, and percieved to be the one with the greatest likelihood of having been emitted by intelligent lifeforms despite its specific origins still being uncertain to this day.

With technology advancing faster than ever, and more and more discoveries being made every day, is the day we contact extraterrestrial life almost here?
