.On Nov 16, 1974, human beings delivered their very first information to the stars in an effort to call extraterrestrials. They did this utilizing what was at that point the most extensive radio telescope in the world, situated at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and also Carl Sagan sent their message to the M13 galaxy.
The information was filled in binary code as well as consisted of information concerning human DNA. It also featured bodies of a human, the solar system and also the Arecibo telescope. The concept was actually that if any sort of invaders were to acquire the signal and identify exactly how to decode it, they would understand where it originated from.
Due to the fact that M13 is 25,000 light-years away, it will certainly take 25,000 years for any sort of M13 aliens to hear our message– if they are level certainly there. The Arecibo information is actually a single of a number of messages wanted for space beings. Our experts have actually likewise consisted of notifications on numerous space capsule, including Trailblazer and Voyager.
