.On Nov 16, 1974, people sent their initial message to the stars in an effort to call extraterrestrials. They performed this using what was then the largest broadcast telescope in the world, located at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake and also Carl Sagan sent their information to the M13 galaxy.
The notification was actually written in binary code as well as contained info regarding individual DNA. It additionally consisted of bodies of an individual, the planetary system and also the Arecibo telescope. The tip was actually that if any invaders were to receive the signal as well as determine just how to decipher it, they would know where it stemmed from.
Since M13 is 25,000 light-years away, it is going to take 25,000 years for any M13 aliens to hear our message– if they are actually even out there certainly. The Arecibo notification is just one of many notifications meant for space beings. We have actually additionally featured messages on several spacecraft, including Trailblazer as well as Voyager.
