.On Nov 16, 1974, humans delivered their first notification to the stars in an effort to get in touch with extraterrestrials. They performed this using what was actually after that the most extensive radio telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led by Frank Drake and also Carl Sagan sent their message to the M13 galaxy.
The information was filled in binary code and also had info about human DNA. It also featured amounts of an individual, the solar system as well as the Arecibo telescope. The suggestion was actually that if any invaders were to get the signal as well as figure out how to translate it, they would certainly recognize where it came from.
Since M13 is actually 25,000 light-years away, it will take 25,000 years for any kind of M13 invaders to hear our message– if they are actually even out there. The Arecibo message is actually just one of several notifications planned for space beings. Our company have also featured messages on many space probe, including Leader and Voyager.
