The WOW Signal: 72 Seconds From Deep Space

追加: 2026-06-03

[00:00:00]On August 15th, 1977, astronomer Jerry Ehman was reviewing radio telescope data when he saw something impossible, a signal from deep space more powerful than anything they'd ever detected. He grabbed a red pen and scrawled "Wow" in the margin. The transmission lasted exactly 72 seconds, then it vanished. It didn't match any known satellite, any natural phenomenon, any earthly [music] source. Scientists have searched for decades, pointed massive telescopes at the exact same spot in space. Nothing.

[00:00:29]The signal has never returned, and no one can explain what sent it. What was broadcasting from the depths of space that night?
