The Wow! Signal

The Wow! signal was received in the summer of 1977 and remains to this day the strongest candidate for an extraterrestrial message ever observed in the history of radio. The attending astronomer, Jerry Ehman, wrote the word “Wow!” in the margins of the signal’s printout. The signal lasted 72 seconds, then fell silent and never repeated. Its origin remains unknown.
