.On Nov 16, 1974, people delivered their very first message to the celebrities in an attempt to speak to extraterrestrials. They did this utilizing what was actually then the most extensive broadcast telescope in the world, located at the Arecibo Observatory in Puerto Rico. A group of researchers led by Frank Drake and Carl Sagan sent their information to the M13 star cluster.
The notification was actually written in binary code as well as had relevant information about human DNA. It additionally included numbers of a human, the solar system as well as the Arecibo telescope. The tip was that if any invaders were actually to get the sign and also find out just how to decode it, they would certainly know where it came from.
Because M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any M13 aliens to hear our message– if they are actually even out there certainly. The Arecibo message is actually only one of numerous messages aimed for e.t.s. We have likewise included messages on many spacecraft, such as Pioneer and Voyager.
