.On November 16, 1974, humans delivered their initial information to the celebrities in an effort to speak to e.t.s. They performed this using what was then the most extensive radio telescope worldwide, located at the Arecibo Observatory in Puerto Rico. A team of experts led by Frank Drake and Carl Sagan sent their information to the M13 galaxy.
The notification was written in binary code and included information regarding human DNA. It also featured numbers of an individual, the solar system and the Arecibo telescope. The suggestion was actually that if any sort of aliens were to acquire the sign and figure out how to translate it, they will recognize where it came from.
Because M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any kind of M13 aliens to hear our information– if they are actually even out there. The Arecibo information is actually only one of numerous messages intended for e.t.s. Our team have also featured information on numerous spacecraft, like Leader and also Voyager.
