The Wow! Signal

In 1977, a strong radio signal was detected by the Big Ear radio telescope at Ohio State University. The signal, known as the “Wow! Signal,” was a brief burst of radio waves that appeared to come from the direction of the constellation Sagittarius. The signal was so unusual and powerful that the astronomer who discovered it, Dr. Jerry Ehman, wrote “Wow!” on the printout.

Despite extensive efforts to locate the source of the signal, it has never been detected again. Some speculate that the signal could have been a transmission from an extraterrestrial civilization, while others suggest it may have been caused by natural cosmic phenomena. The Wow! Signal remains one of the most intriguing unsolved mysteries in the search for extraterrestrial intelligence.
