.On Nov 16, 1974, people sent their 1st notification to the superstars in a try to get in touch with extraterrestrials. They did this using what was actually then the biggest broadcast telescope around the world, found at the Arecibo Observatory in Puerto Rico. A team of experts led by Frank Drake as well as Carl Sagan sent their information to the M13 star cluster.
The notification was actually written in binary code and contained info concerning human DNA. It also included figures of an individual, the planetary system and also the Arecibo telescope. The idea was actually that if any sort of aliens were to acquire the indicator and also determine exactly how to decode it, they will recognize where it arised from.
Due to the fact that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any M13 aliens to hear our information– if they are even out there. The Arecibo message is actually just one of a number of messages meant for e.t.s. Our company have actually additionally featured notifications on many space probe, such as Trailblazer and also Voyager.
