.On Nov 16, 1974, humans sent their first notification to the celebrities in an attempt to talk to space beings. They did this using what was then the biggest radio telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake and also Carl Sagan sent their notification to the M13 galaxy.
The notification was recorded binary code and had info about human DNA. It additionally consisted of bodies of an individual, the planetary system and the Arecibo telescope. The idea was actually that if any invaders were actually to get the sign and also identify exactly how to decipher it, they would certainly understand where it originated from.
Due to the fact that M13 is 25,000 light-years away, it will take 25,000 years for any M13 aliens to hear our message– if they are even out certainly there. The Arecibo information is actually a single of numerous messages intended for space beings. We have also consisted of information on a number of space capsule, including Trailblazer and also Voyager.
