.On Nov 16, 1974, human beings delivered their first notification to the stars in an attempt to speak to extraterrestrials. They performed this utilizing what was at that point the biggest broadcast telescope around the world, found at the Arecibo Observatory in Puerto Rico. A team of scientists led through Frank Drake as well as Carl Sagan sent their notification to the M13 galaxy.
The message was filled in binary code and also consisted of details concerning individual DNA. It likewise consisted of bodies of an individual, the solar system and the Arecibo telescope. The idea was actually that if any kind of aliens were actually to get the sign and determine how to decipher it, they would understand where it arised from.
Since M13 is 25,000 light-years away, it will take 25,000 years for any type of M13 invaders to hear our information– if they are actually even out certainly there. The Arecibo information is actually only one of a number of information meant for e.t.s. We have actually also consisted of messages on a number of space probe, including Pioneer and also Voyager.
