How a 72 Second Signal From Space Became the Biggest Mystery in Astronomy
In 1977, astronomers recorded an unexplained 72-second radio signal stronger than anything else detected from deep space. Dubbed the “Wow Signal,” it came and went without warning, never repeating again. Decades later, scientists still debate whether it was a cosmic anomaly or evidence of intelligent life.

In 1977, a massive 72-second radio signal hit Earth from deep space—so strong and so precise that the astronomer who found it circled it and wrote one word: “WOW.” They searched for it for decades… but the signal never returned. No stars nearby. No planets. No explanation. Was it a message? A mistake? Or contact from something out there? #UnknownTales #WowSignal #AlienMystery #TrueStory #UnsolvedMysteries #SpaceSignal | Unknown Tales

Back in 1977, a mysterious signal reached Earth — lasting only seventy-two seconds. Detected by Ohio State’s Big Ear Radio Observatory while scanning the constellation Sagittarius, the signal was unlike anything ever heard before. Astronomers called it the Wow! signal. It appeared on the same hydrogen frequency scientists use in the search for extraterrestrial intelligence — 1420 MHz — and has never been detected again. Nearly fifty years later, we still don’t know who, or what, sent it. #space
