.On Nov 16, 1974, people sent their 1st notification to the celebrities in an effort to consult with extraterrestrials. They performed this using what was actually after that the biggest radio telescope around the world, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake as well as Carl Sagan sent their information to the M13 star cluster.
The notification was actually written in binary code and included info regarding human DNA. It likewise featured figures of an individual, the planetary system and the Arecibo telescope. The idea was actually that if any sort of invaders were to get the sign and also figure out just how to translate it, they will know where it arised from.
Because M13 is actually 25,000 light-years away, it will take 25,000 years for any M13 invaders to hear our information– if they are level there. The Arecibo information is just one of many information aimed for space beings. Our team have likewise included information on a number of space capsule, like Leader and Voyager.
