Wow! Signal

The Wow! Signal was a strong extraterrestrial radio signal received by the Big Ear radio telescope on August 15, 1977. The famous code 6EQUJ5 describes the intensity of the signal, with U denoting a signal 30 times stronger than the cosmic background. The signal was never received again, and the Big Ear telescope was disassembled in the late 1990s.
