“Radio, The Big Ear, And The Wow! Signal” is copyrighted by Rick Scott. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteOhio State University's radio telescope, "The Big Ear," was one of the first and largest listeners for signals from space. It was designed by John Kraus and relied on Earth's rotation to help scan the sky. In 1977, The Big Ear detected the "Wow!" signal, a strong, narrow-band radio signal that remains unexplained. It was a tantalizing hint of possible extraterrestrial intelligence.
