.On Nov 16, 1974, humans delivered their very first notification to the stars in a try to get in touch with space beings. They did this utilizing what was actually then the most extensive broadcast telescope around the world, situated at the Arecibo Observatory in Puerto Rico. A group of scientists led by Frank Drake and Carl Sagan sent their information to the M13 star cluster.
The information was actually written in binary code and consisted of information concerning human DNA. It likewise consisted of numbers of an individual, the planetary system and the Arecibo telescope. The concept was that if any kind of invaders were actually to receive the signal and also find out how to decipher it, they would certainly understand where it originated from.
Since M13 is 25,000 light-years away, it will certainly take 25,000 years for any M13 aliens to hear our message– if they are level certainly there. The Arecibo message is only one of several notifications wanted for space beings. We have actually likewise featured notifications on many space capsule, like Pioneer as well as Voyager.
