.On Nov 16, 1974, people sent their first information to the stars in a try to contact extraterrestrials. They did this using what was at that point the biggest radio telescope on earth, situated at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and Carl Sagan sent their notification to the M13 star cluster.
The message was written in binary code as well as consisted of information concerning human DNA. It additionally consisted of bodies of a human, the planetary system as well as the Arecibo telescope. The concept was that if any kind of invaders were actually to get the sign as well as figure out just how to decode it, they would understand where it originated from.
Given that M13 is 25,000 light-years away, it is going to take 25,000 years for any M13 invaders to hear our message– if they are actually level there certainly. The Arecibo message is a single of several notifications meant for extraterrestrials. Our team have actually additionally consisted of notifications on many spacecraft, including Leader and Voyager.
