Wow Signal - The Most Mysterious Radio Signal Ever Detected

Wow Signal - The Most Mysterious Radio Signal Ever Detected In 1977, astronomers detected an unusually strong and unexplained radio signal coming from deep space. The signal lasted just 72 seconds — but it was so remarkable that astronomer Jerry Ehman famously wrote “Wow!” on the computer printout. Known as the Wow! Signal, it remains one of the most intriguing events in the history of radio astronomy. It appeared to come from the direction of the constellation Sagittarius, but despite decades of research, astronomers have never conclusively determined what caused it. Was it a rare natural cosmic event? Human-made interference? Or something we still don't understand? The Wow! Signal has never been reliably detected again, making its true origin an enduring mystery. 🔭 What do you think caused the Wow! Signal?
