.On November 16, 1974, humans sent their first information to the superstars in an effort to call extraterrestrials. They did this using what was then the largest radio telescope on earth, located at the Arecibo Observatory in Puerto Rico. A team of researchers led by Frank Drake as well as Carl Sagan sent their message to the M13 star cluster.
The notification was recorded binary code as well as consisted of details concerning human DNA. It likewise consisted of figures of a human, the solar system and the Arecibo telescope. The suggestion was that if any kind of invaders were actually to acquire the signal and also find out how to decode it, they would certainly recognize where it arised from.
Because M13 is 25,000 light-years away, it will definitely take 25,000 years for any kind of M13 invaders to hear our information– if they are even out there certainly. The Arecibo information is actually only one of several information meant for extraterrestrials. Our experts have actually likewise consisted of information on many spacecraft, like Leader and also Voyager.
