.On Nov 16, 1974, human beings sent their very first notification to the superstars in an attempt to talk to e.t.s. They did this using what was after that the most extensive radio telescope worldwide, positioned at the Arecibo Observatory in Puerto Rico. A team of scientists led through Frank Drake and Carl Sagan sent their message to the M13 galaxy.
The notification was actually recorded binary code and consisted of information regarding human DNA. It additionally consisted of figures of an individual, the planetary system and the Arecibo telescope. The idea was that if any aliens were to receive the signal as well as figure out exactly how to decipher it, they would understand where it arised from.
Due to the fact that M13 is 25,000 light-years away, it is going to take 25,000 years for any M13 aliens to hear our message– if they are actually level there certainly. The Arecibo information is actually only one of a number of notifications intended for e.t.s. Our experts have actually likewise included notifications on many space capsule, like Trailblazer as well as Voyager.
