I have read about that, very interesting. Something seems a little fishy bettin on it being hush hush.
In August 1977, a sky survey conducted with Ohio State University's "Big Ear" radio telescope found what has become known as the 'Wow' signal. Registering an enormous signal strength, the shape of the signal had the characteristic rise and fall expected for its short 72 second lifetime. But a hitch remains: the signal has not been retrieved from other sky surveys, making it more anomaly than confirmable cosmic source.
