.On Nov 16, 1974, humans delivered their first information to the celebrities in an attempt to speak to extraterrestrials. They performed this utilizing what was then the largest radio telescope on the planet, found at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and also Carl Sagan delivered their notification to the M13 galaxy.
The notification was written in binary code and consisted of relevant information regarding human DNA. It also featured numbers of a human, the solar system as well as the Arecibo telescope. The tip was that if any aliens were actually to receive the signal and also determine just how to decode it, they would certainly know where it stemmed from.
Considering that M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any type of M13 invaders to hear our information– if they are even out there. The Arecibo information is actually a single of many notifications aimed for e.t.s. Our team have actually additionally included messages on many spacecraft, such as Trailblazer and Voyager.
