Breaking News:  NASA and SETI Astronomers detect an artificial alien radio signal originating from Ganymede, oneof Jupiter’s largest moons.  When did this happen?  Believe it or notbut this scenario is supposed to have taken place during the 1980’s. According to at least one researcher, Rupert Matthews, this was actuallytold to him by an actual NASA astronomer who was working closely withSETI.  While this may sound extremely far fetched, it has only been inthe last several decades that astronomers have confirmed strong evidencefor liquid oceans underneath all three of Jupiter’s largest moons:Europa, Ganymede and Callisto.  And as everyone knows, water is theelement that must be present for life to develop so while the scenariocould be viewed as highly unlikely, it is certainly not impossible. Unfortunately, the signal appears to have been only detected for a briefperiod of time and has not been detected since so it could be said thatthese aliens might have been just visiting the local area and are notpermanent residents of the moon. 

As to the signal itself, this is what Rupert Matthews reports in his book Alien Encounters: True Stories of Aliens, UFO’s and other E.T. Phenomenon which was published in 2008.  NASA and SETI astronomers picked up on a radiosignal that seemed to have a coded message sometime in the mid 1980’s. The signal was coming from Jupiter’s moon Ganymede and was definitelyartificial in nature.  The signal was run through multiple computers andno sense could be made as to the meaning of it.  President Reagan wasnotified and an international conference was assembled to determine howto make an attempt to contact whatever beings were sending the message. Eventually it was decided to send a signal to the exact location thatthe message was coming from on Ganymede.  This message would be sent inMorse Code which was considered to be the easiest for an aliencivilization to decode.  It would read “We have received your signal,but we do not understand it.  Please resend your signal using thislanguage and transmission code.”  Immediately after this message wassent, the mysterious signal from Ganymede ceased its transmission soeveryone assumed that we would receive a new signal in Morse Code in aquick period of time.  But day after day and then week after week nosignal came and officials began to give up hope of actually receiving aresponse.  Finally after more than a month, a signal was  detectedcoming from the original radio source on Ganymede and incredibly it wasin Morse Code.  Eagerly NASA scientists translated our first directcontact with an alien civilization.  And it said “We were not talking toyou.”
