[00:00:00]In August 1977, radio astronomers detected a powerful narrow band signal.

[00:00:05]It was picked up by the Ohio State University Big Ear radio telescope. One researcher, Jerry Ehman, saw the printout and circled it, writing the word wow. The signal lasted for 72 seconds, centered precisely on the hydrogen line at 1420 MHz.

[00:00:23]This frequency is a key signature for extraterrestrial communication. However, the signal was never repeated.

[00:00:30]Subsequent searches, including hypotheses involving comets, failed to find an identical source. The source remains unknown.

[00:00:38]Despite the excitement, the Wow signal remains one of science's greatest unanswered questions.

[00:00:44]Could it be natural or something far more advanced? What do you think generated the Wow signal? Comment your theory below.
