.On November 16, 1974, human beings sent their first notification to the stars in an effort to talk to extraterrestrials. They did this using what was actually at that point the largest broadcast telescope around the world, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake and also Carl Sagan delivered their notification to the M13 star cluster.
The notification was recorded binary code as well as consisted of information concerning human DNA. It also consisted of bodies of a human, the solar system and also the Arecibo telescope. The suggestion was that if any invaders were to get the signal and identify how to decipher it, they would certainly understand where it originated from.
Because M13 is 25,000 light-years away, it will take 25,000 years for any M13 aliens to hear our information– if they are level there. The Arecibo information is actually a single of several information wanted for e.t.s. Our company have actually also consisted of messages on many spacecraft, like Leader as well as Voyager.
