[00:00:00]Do you know what the Wow signal was? In 1977, a radio telescope detected a powerful 72-second signal from deep space, so unusual that a scientist circled it and wrote a hydrogen, the most common element in the universe.

[00:00:12]It's narrow band structure looked artificial, and since hydrogen is a universal marker, scientists briefly considered it could be an intentional extraterrestrial signal, but it was never detected again. Researchers suggest a powerful cosmic burst, like a magnetar flare, may have passed through hydrogen clouds, bending and amplifying radio waves near that frequency, creating a one-time signal that only looked intelligent.
