As we approach the 40th anniversary of the legendary 'Wow!' signal, a new study appears to have finally determined its origin.
The puzzling radio signal has vexed scientists after it was noticed in August of 1977 by a radio astronomer, who noted its anomalous nature by scribbling the word 'Wow!' next to it in his notes.
Since that time, researchers have attempted to decipher the source of the signal, but continually fell short when it came to solving the mystery.
However, a newly-published, peer-reviewed paper by astronomer Antonio Paris may close the case for good.
