.On Nov 16, 1974, humans delivered their 1st message to the superstars in an effort to contact space beings. They performed this utilizing what was at that point the biggest broadcast telescope worldwide, located at the Arecibo Observatory in Puerto Rico. A group of researchers led by Frank Drake and also Carl Sagan delivered their message to the M13 star cluster.
The information was actually written in binary code and had relevant information concerning individual DNA. It likewise included figures of a human, the planetary system and also the Arecibo telescope. The suggestion was actually that if any invaders were to obtain the sign as well as determine just how to translate it, they will recognize where it stemmed from.
Considering that M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any kind of M13 invaders to hear our information– if they are actually level there. The Arecibo message is actually just one of numerous information planned for space beings. We have actually likewise featured notifications on a number of space probe, like Leader and Voyager.
