.On November 16, 1974, human beings sent their 1st notification to the stars in an effort to call e.t.s. They performed this utilizing what was then the biggest broadcast telescope around the world, found at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan sent their notification to the M13 galaxy.
The information was actually filled in binary code and also consisted of details about human DNA. It additionally included bodies of an individual, the solar system and the Arecibo telescope. The concept was actually that if any kind of aliens were actually to obtain the signal and figure out just how to decipher it, they would certainly know where it stemmed from.
Because M13 is 25,000 light-years away, it will certainly take 25,000 years for any type of M13 invaders to hear our notification– if they are actually level there. The Arecibo message is actually a single of a number of messages intended for e.t.s. Our team have actually likewise consisted of messages on several space capsule, such as Leader and also Voyager.
