.On Nov 16, 1974, humans delivered their 1st notification to the superstars in an attempt to call extraterrestrials. They performed this using what was actually at that point the biggest radio telescope worldwide, located at the Arecibo Observatory in Puerto Rico. A team of researchers led by Frank Drake and Carl Sagan sent their message to the M13 galaxy.
The information was recorded binary code and also included info about individual DNA. It likewise consisted of figures of an individual, the planetary system and also the Arecibo telescope. The idea was actually that if any sort of aliens were actually to get the sign and also figure out just how to decipher it, they would know where it came from.
Given that M13 is actually 25,000 light-years away, it is going to take 25,000 years for any type of M13 invaders to hear our information– if they are actually flatten certainly there. The Arecibo message is actually just one of a number of information meant for extraterrestrials. We have likewise featured notifications on numerous spacecraft, including Pioneer as well as Voyager.
