For researchers seeking answers to the question of whether we are alone in the universe, one event nearly half a century ago lingers even today — the so-called "Wow! Signal" detected back in 1977.
That strong, baffling radio episode was captured by Ohio State University's Search for Extraterrestrial Intelligence (SETI) project, also known as the "Big Ear." It has been viewed by some as one of the oddest radio transmissions from afar ever detected, also cited as compelling evidence for extraterrestrial intelligence.
