.On November 16, 1974, humans delivered their 1st notification to the superstars in an attempt to consult with e.t.s. They performed this using what was at that point the largest radio telescope in the world, situated at the Arecibo Observatory in Puerto Rico. A team of researchers led by Frank Drake as well as Carl Sagan delivered their notification to the M13 galaxy.
The message was recorded binary code and contained info concerning individual DNA. It also included bodies of a human, the solar system as well as the Arecibo telescope. The concept was that if any kind of invaders were to get the indicator and figure out exactly how to decode it, they would certainly know where it came from.
Because M13 is actually 25,000 light-years away, it will take 25,000 years for any type of M13 aliens to hear our information– if they are level there certainly. The Arecibo notification is only one of numerous messages planned for space beings. We have actually likewise consisted of information on several space capsule, like Leader and Voyager.
