.On November 16, 1974, humans sent their initial information to the superstars in an effort to call e.t.s. They did this using what was then the most extensive broadcast telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake as well as Carl Sagan sent their information to the M13 star cluster.
The information was recorded binary code and consisted of information concerning human DNA. It also consisted of numbers of a human, the planetary system as well as the Arecibo telescope. The idea was that if any type of aliens were to get the sign and also find out how to translate it, they will understand where it stemmed from.
Given that M13 is actually 25,000 light-years away, it is going to take 25,000 years for any type of M13 invaders to hear our notification– if they are even out certainly there. The Arecibo information is actually only one of a number of information aimed for extraterrestrials. We have additionally featured notifications on numerous space capsule, including Pioneer and Voyager.
