.On November 16, 1974, human beings sent their very first message to the superstars in an attempt to contact extraterrestrials. They did this utilizing what was at that point the largest broadcast telescope on the planet, found at the Arecibo Observatory in Puerto Rico. A group of experts led through Frank Drake as well as Carl Sagan delivered their notification to the M13 galaxy.
The information was filled in binary code and also included info about human DNA. It also consisted of numbers of a human, the planetary system as well as the Arecibo telescope. The idea was that if any type of invaders were to acquire the signal as well as find out just how to decipher it, they would know where it arised from.
Because M13 is actually 25,000 light-years away, it will take 25,000 years for any type of M13 aliens to hear our information– if they are level there. The Arecibo message is actually just one of numerous messages wanted for e.t.s. Our experts have likewise featured information on numerous spacecraft, like Pioneer as well as Voyager.
