.On November 16, 1974, humans delivered their first message to the superstars in an attempt to speak to extraterrestrials. They performed this utilizing what was then the most extensive broadcast telescope around the world, situated at the Arecibo Observatory in Puerto Rico. A group of experts led by Frank Drake and also Carl Sagan sent their notification to the M13 star cluster.
The notification was recorded binary code as well as included relevant information concerning human DNA. It also included bodies of an individual, the planetary system and also the Arecibo telescope. The concept was that if any kind of aliens were actually to acquire the sign and figure out just how to decode it, they would certainly recognize where it arised from.
Because M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any sort of M13 aliens to hear our notification– if they are level certainly there. The Arecibo notification is only one of numerous messages planned for e.t.s. Our experts have actually additionally consisted of notifications on several spacecraft, like Trailblazer and Voyager.
