.On November 16, 1974, human beings sent their 1st message to the stars in a try to speak to e.t.s. They did this using what was actually then the largest broadcast telescope around the world, situated at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and also Carl Sagan delivered their message to the M13 star cluster.
The information was filled in binary code as well as included information about individual DNA. It additionally featured numbers of a human, the solar system and the Arecibo telescope. The concept was actually that if any invaders were actually to obtain the sign and identify exactly how to translate it, they would certainly know where it originated from.
Considering that M13 is actually 25,000 light-years away, it will take 25,000 years for any type of M13 aliens to hear our notification– if they are actually level there. The Arecibo information is actually just one of several messages meant for extraterrestrials. Our team have also featured information on numerous spacecraft, such as Trailblazer as well as Voyager.
