In 1977, a radio telescope in Ohio picked up a mysterious 72-second signal from deep space. It was so precise, so powerful, and so clean… a scientist literally wrote “Wow!” in the margins.

This is the Wow! Signal—one of the most puzzling and hotly debated moments in the history of the Search for Extraterrestrial Intelligence (SETI).

Could it have been a genuine alien transmission? Why haven’t we ever heard it again? And how close are we really to explaining it?

Gordy breaks down everything you need to know about this unrepeatable cosmic burst, the technology that detected it, the theories that followed, and the 2024 magnetar hypothesis that might finally unlock the mystery.

👉 Stick around for a breakdown that’s perfect for anyone fascinated by space mysteries, extraterrestrial life, radio astronomy, and the question we’re all still asking—are we alone?
