On August 15, 1977, a radio telescope in Ohio detected a mysterious 72-second radio signal from the direction of the Sagittarius constellation, which was 30 times stronger than background noise and came on the exact frequency NASA had predicted aliens might use for interstellar communication; the astronomer who discovered it circled the signal in red ink and wrote 'Wow' beside it, and despite decades of subsequent searches by every telescope on Earth, the signal has never been detected again, leaving its origin unexplained.

The 1977 Signal NASA Still Cannot ExplainAñadido:
On August 15th, 1977, a radio telescope picked up something it could not explain.
For 72 seconds, a signal poured in from the direction of Sagittarius, [music] 30 times stronger than background noise.
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.
Was someone reaching out one time and never trying again?
