The Wow! Signal, detected in 1977, was a 72-second burst of radio energy at 1420 MHz (the hydrogen line frequency) that was 30 times stronger than background space noise, originating from a sun-like star 1,800 light-years away in Sagittarius; while initially considered potential evidence of extraterrestrial intelligence, new 2026 simulations suggest it may have been a natural cosmic hydrogen maser caused by a nearby supernova explosion, though the signal's unique intensity and one-in-a-billion alignment remain unexplained.
