The "WOW" Signal

The Wow! signal is a mysterious radio signal detected on August 15, 1977, by Ohio State University's Big Ear radio telescope. It lasted 72 seconds and displayed characteristics typical of a potential extraterrestrial origin. The signal's origin remains unknown, and efforts to replicate it have been inconclusive. The Wow! signal was a strong narrowband radio signal in the 1420 MHz hydrogen line, a frequency considered significant for potential interstellar communication. Despite numerous follow-up searches, the signal has not been detected again. Its origin and nature continue to spark speculation and intrigue within the scientific and SETI (Search for Extraterrestrial Intelligence) communities.
