.On November 16, 1974, human beings delivered their first information to the stars in an attempt to consult with e.t.s. They performed this using what was after that the largest broadcast telescope on the planet, located 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 star cluster.
The notification was filled in binary code and had details about individual DNA. It additionally featured amounts of a human, the planetary system and the Arecibo telescope. The concept was that if any kind of invaders were to obtain the indicator and identify exactly how to decipher it, they would certainly know where it stemmed from.
Given that M13 is actually 25,000 light-years away, it will take 25,000 years for any sort of M13 aliens to hear our notification– if they are even out certainly there. The Arecibo notification is actually a single of several messages intended for space beings. We have likewise featured messages on numerous space capsule, including Trailblazer as well as Voyager.
