My Hypothesis on The “WOW” Signal

Back in 1977 Astronomer Jerry Ehman was using the Ohio State University’s Big Ear Radio Telescope sweeping for potential signals from alien civilizations. While monitoring the skies he came across a very powerful signal that lasted for exactly 72 seconds coming from the area of Chi Sagittarii. Dubbed the WOW signal because he circled the numbers and letters on a printed readout and wrote Wow! next to it.
