A scientist may have pinpointed the origin of the Wow! Signal, the most famous alien radio broadcast in history, making it an ideal candidate for future research and observations in the Search for Extraterrestrial Intelligence (SETI).

The study, which was polished in the peer-reviewed academic periodical The International Journal of Astrobiology, suggests that the famous signal could very well have come from a star located in the Sagittarius constellation that is similar to our own Sun.

What is the Wow! Signal?

The Wow! Signal is easily the most famous and enduring extraterrestrial radio transmission to Earth in history and to this day is the strongest candidate for a genuine radio transmission from an intelligent source.

The signal itself is a strong narrowband radio signal and was recorded on August 15, 1977 at the Big Ear radio telescope at Ohio State University. 

The signal, which was detected over a period of 72 seconds (that was as long as the telescope was capable of observing, and it likely lasted longer), was then noticed by astronomer Jerry R. Ehman who, when looking over the printout of the data, circled the signal, noted by the sequence 6EQUJ5 and famously wrote "Wow!" next to it.

The sequence in question does not refer to any message broadcast in the signal, but merely referred to the intensity variation.

However, the signal, or any other like it, has yet to be detected again.
