.On Nov 16, 1974, humans sent their very first notification to the stars in a try to speak to e.t.s. They performed this utilizing what was actually at that point the largest radio telescope on earth, situated at the Arecibo Observatory in Puerto Rico. A group of experts led through Frank Drake and also Carl Sagan sent their notification to the M13 galaxy.
The information was actually recorded binary code and also had relevant information regarding human DNA. It also included bodies of a human, the planetary system and the Arecibo telescope. The idea was that if any kind of aliens were to receive the sign and also figure out exactly how to decode it, they would understand where it came from.
Due to the fact that M13 is 25,000 light-years away, it is going to take 25,000 years for any type of M13 aliens to hear our information– if they are level there. The Arecibo information is actually just one of many messages meant for extraterrestrials. We have actually additionally included information on several space probe, like Leader and also Voyager.
