The Wow! Signal

The Wow! Signal remains one of the most compelling potential evidences of extraterrestrial communication. Detected in 1977 by Ohio State University's Big Ear radio telescope, this strong, narrowband radio signal lasted 72 seconds and matched the expected characteristics of an interstellar transmission. Coming from the Sagittarius constellation, it was 30 times stronger than cosmic background noise. Despite numerous attempts, the signal was never detected again, adding to its mystery. While explanations range from comet emissions to equipment anomalies, the Wow! Signal continues to fuel scientific debate about intelligent alien life.
