.On Nov 16, 1974, humans sent their 1st message to the celebrities in a try to contact extraterrestrials. They performed this using what was actually then the largest broadcast telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A team of experts led through Frank Drake as well as Carl Sagan sent their notification to the M13 galaxy.
The notification was filled in binary code as well as had details concerning human DNA. It likewise included bodies of a human, the solar system as well as the Arecibo telescope.

Because M13 is 25,000 light-years away, it will take 25,000 years for any type of M13 aliens to hear our message– if they are actually flatten there certainly. The Arecibo message is just one of numerous information meant for e.t.s. We have also featured messages on many spacecraft, such as Trailblazer and also Voyager.
