.On November 16, 1974, people delivered their 1st information to the stars in an effort to contact space beings. They did this using what was actually at that point the biggest radio telescope in the world, located at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and also Carl Sagan sent their information to the M13 galaxy.
The notification was actually written in binary code and also contained info concerning individual DNA. It also included numbers of a human, the solar system as well as the Arecibo telescope. The idea was that if any kind of invaders were to get the sign and also find out how to translate it, they would certainly recognize where it arised from.
Since M13 is 25,000 light-years away, it is going to take 25,000 years for any kind of M13 aliens to hear our information– if they are flatten certainly there. The Arecibo message is actually a single of several messages meant for extraterrestrials. We have actually likewise consisted of notifications on several space probe, including Trailblazer and Voyager.
