The Mystery of the Wow Signal

In 1977, astronomer Jerry Ehman was scanning the skies using Ohio State University's Big Ear radio telescope when he detected something extraordinary\u2014a powerful 72-second signal from space. It was so unique that Ehman circled it on the printout and wrote "Wow!" in the margin, giving it its iconic name.

The signal came from the constellation Sagittarius and matched the characteristics of an interstellar broadcast. Despite extensive follow-up searches, the signal was never detected again.

Was it a message from an alien civilization attempting to communicate? Or was it just an unexplained cosmic coincidence, perhaps a burst of natural space noise?

The Wow! Signal remains one of the greatest unsolved mysteries of the universe. What do you think\u2014contact or coincidence?
