One night in 1967, a pair of astronomers, Jocelyn Bell and Antony Hewish, detected a radio signal in an observatory in the UK.
It was one of the strangest things ever found. How could they explain it? Every 1.337302088331 seconds it pulsed with precision rivaling modern technology.
The astronomers were astounded. It didn’t seem like a natural phenomenon and we had no way to explain such a beacon’s origins.
In homage to the obvious answer the signal’s origin was dubbed LGM-1.
“Little Green Men”.
It was later found to be a whole new type of star: a pulsar. A stellar object that emits beacons with such regularity they’re used as clocks. The story is familiar though: our imagination fails to live up to the reality that is the cosmos.
Somehow the universe never ceases to surprise and amaze us.
*Also before I’m asked, yes: Joy Division did use an image of the radio signals - so there’s a little pop history for you too.
