00:00On this day in space. In 1977 astronomers using Ohio State University's Big Ear
00:07radio telescope detected the famous WOW signal, which to this day is one of the
00:11strongest pieces of evidence that we are not alone in the universe. Astronomer
00:15Jerry Amon was using the telescope to scan a region in the constellation
00:17Sagittarius when it detected a 72 second long radio burst. The signal was too
00:22strong to be explained by background noise and researchers determined that it
00:26was very unlikely that the signal came from anything on Earth. Despite their
00:29best efforts, astronomers have not been able to detect any other radio signals
00:32like it. And that's what happened on this day in space.
