.On Nov 16, 1974, human beings delivered their very first message to the stars in an effort to speak to e.t.s. They did this using what was actually then the largest broadcast telescope in the world, found at the Arecibo Observatory in Puerto Rico. A group of experts led through Frank Drake and also Carl Sagan delivered their message to the M13 galaxy.
The message was recorded binary code as well as had relevant information regarding individual DNA. It additionally included numbers of a human, the solar system and the Arecibo telescope. The concept was that if any invaders were actually to obtain the indicator and also identify how to decipher it, they would certainly understand where it originated from.
Given that M13 is actually 25,000 light-years away, it is going to take 25,000 years for any type of M13 aliens to hear our information– if they are flatten there certainly. The Arecibo information is just one of a number of notifications aimed for e.t.s. Our team have likewise consisted of notifications on several space capsule, like Trailblazer and Voyager.
