.On Nov 16, 1974, human beings delivered their 1st notification to the stars in an attempt to consult with e.t.s. They performed this using what was at that point the most extensive broadcast telescope in the world, positioned at the Arecibo Observatory in Puerto Rico. A group of experts led by Frank Drake as well as Carl Sagan sent their information to the M13 galaxy.
The notification was recorded binary code and also consisted of relevant information about human DNA. It also consisted of figures of an individual, the planetary system and the Arecibo telescope. The tip was that if any kind of aliens were to acquire the signal as well as determine how to decode it, they will understand where it came from.
Since M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any M13 invaders to hear our information– if they are level there. The Arecibo information is actually just one of several information intended for extraterrestrials. Our experts have additionally included messages on numerous space capsule, such as Trailblazer and also Voyager.
