.On November 16, 1974, human beings delivered their initial message to the stars in a try to contact extraterrestrials. They did this utilizing what was then the largest radio telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A group of researchers led by Frank Drake and Carl Sagan sent their information to the M13 galaxy.
The information was actually filled in binary code and included relevant information about human DNA. It additionally included bodies of a human, the solar system as well as the Arecibo telescope. The suggestion was actually that if any type of aliens were to obtain the sign and also figure out exactly how to translate it, they would know where it came from.
Because M13 is 25,000 light-years away, it is going to take 25,000 years for any M13 invaders to hear our notification– if they are even out certainly there. The Arecibo message is only one of numerous messages meant for e.t.s. We have actually likewise featured notifications on a number of space probe, like Pioneer and also Voyager.
