Have you heard of the "Wow! Signal"? In 1977, a strong, narrowband radio signal was detected by a radio telescope at Ohio State University. The signal lasted for 72 seconds and was so strong that it was dubbed the "Wow!" signal. Despite numerous attempts to verify the signal, its origin remains a mystery to this day!

Was it a transmission from an alien civilization? Or a natural phenomenon? The Wow! Signal remains one of the most intriguing unsolved mysteries in the search for extraterrestrial intelligence (SETI)!
