Ajouté : 2026-05-22

[00:00:00]On August 15th, 1977, a radio telescope picked up something it could not explain.

[00:00:09]For 72 seconds, a signal poured in from the direction of Sagittarius, [music] 30 times stronger than background noise.

[00:00:20]It came in on the exact frequency NASA had predicted aliens might use to contact [music] us. The astronomer circled it in red ink. Beside it, he wrote one word, "Wow." Every telescope on Earth has scanned that same patch of sky. [music] Satellites ruled out. Earth interference ruled out. Was it a glitch? We still don't understand. One time and never trying [music] again. Follow Curious Vault.
