A mysterious “extraterrestrial” radio signal picked up in 1977 is likely to have a natural origin, scientists have found.
The infamous “Wow” signal sparked global interest when it was captured by Ohio State University’s Search for Extraterrestrial Intelligence (SETI) project nearly 50 years ago.
The team, which was scanning the sky for signs of intelligent life, detected a powerful, 72-second radio burst so unusual that leading astronomer Jerry Ehman scribbled “Wow!” on the computer printout.
