.On Nov 16, 1974, human beings delivered their 1st notification to the celebrities in an attempt to consult with space beings. They performed this using what was after that the largest broadcast telescope in the world, found at the Arecibo Observatory in Puerto Rico. A group of researchers led by Frank Drake and also Carl Sagan sent their information to the M13 star cluster.
The information was actually filled in binary code and included details regarding human DNA. It likewise included bodies of a human, the planetary system as well as the Arecibo telescope. The idea was that if any sort of invaders were to get the indicator as well as find out how to translate it, they will understand where it stemmed from.
Given that M13 is 25,000 light-years away, it will certainly take 25,000 years for any type of M13 invaders to hear our information– if they are actually flatten there certainly. The Arecibo notification is just one of many information wanted for extraterrestrials. We have actually also included information on several spacecraft, including Leader as well as Voyager.
