.On Nov 16, 1974, people sent their 1st notification to the superstars in an attempt to call space beings. They did this utilizing what was after that the most extensive broadcast telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A group of experts led by Frank Drake as well as Carl Sagan sent their notification to the M13 star cluster.
The message was actually filled in binary code and contained relevant information about individual DNA. It also featured numbers of an individual, the solar system and the Arecibo telescope. The concept was actually that if any kind of aliens were actually to receive the indicator and identify how to decode it, they will recognize where it originated from.
Since M13 is 25,000 light-years away, it will take 25,000 years for any type of M13 aliens to hear our notification– if they are level there certainly. The Arecibo notification is just one of many messages wanted for space beings. Our team have actually also included information on many spacecraft, such as Pioneer and also Voyager.
