.On Nov 16, 1974, humans delivered their first notification to the superstars in an attempt to speak to e.t.s. They performed this using what was after that the largest radio telescope around the world, positioned at the Arecibo Observatory in Puerto Rico. A group of experts led by Frank Drake as well as Carl Sagan delivered their notification to the M13 star cluster.
The information was actually written in binary code and also consisted of info concerning human DNA. It also included amounts of a human, the planetary system and the Arecibo telescope. The idea was that if any aliens were actually to obtain the indicator as well as determine how to translate it, they would certainly know where it stemmed from.
Due to the fact that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any M13 aliens to hear our message– if they are level certainly there. The Arecibo information is actually only one of numerous notifications wanted for e.t.s. We have actually additionally included information on a number of space probe, such as Leader as well as Voyager.
