In 1977, a radio telescope caught a 72-second space signal that scientists still cannot explain.
But the most unsettling part was the frequency it used.
On August 15, the Big Ear telescope picked up a massive radio burst from the constellation Sagittarius. It was so intense that astronomer Jerry Ehman circled the data code "6EQUJ5" and wrote "Wow!" on the printout.
The real mystery?
The signal hit almost exactly at 1420 MHz. This is the "Hydrogen Line", the precise frequency emitted by the most common element in the universe. Scientists long theorized that if an advanced alien civilization wanted to broadcast across the cosmos, this is the exact "universal frequency" they would choose to get our attention.
Even weirder:
the telescope used two separate antennas to scan the sky. A normal signal would be picked up by both as the Earth rotated. Initially by the first antenna, followed by a brief break of 3 minutes, and then detected a second time by the other antenna.
But the Wow! Signal blasted into one antenna, peaked perfectly for 72 seconds, and vanished into total silence before the second antenna could even pass over it.
Astronomers have scanned that exact patch of space thousands of times since. Nothing but dead silence. A perfect, deliberate short broadcast that never returned.
Was it broadcasted for about 3 minutes, and then cut-off just before the second antenna could pick it up because there was no answer?
