.On November 16, 1974, people delivered their 1st notification to the stars in an effort to call space beings. They did this utilizing what was actually at that point the biggest broadcast telescope on earth, located at the Arecibo Observatory in Puerto Rico. A team of scientists led through Frank Drake and also Carl Sagan delivered their notification to the M13 star cluster.
The message was filled in binary code and included info regarding human DNA. It also featured bodies of a human, the solar system as well as the Arecibo telescope. The concept was actually that if any type of invaders were actually to acquire the signal as well as identify just how to decipher it, they would recognize where it originated from.
Since M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any sort of M13 invaders to hear our notification– if they are even out certainly there. The Arecibo message is actually a single of several messages planned for e.t.s. We have actually also consisted of messages on several space probe, like Pioneer and Voyager.
