.On Nov 16, 1974, humans delivered their initial message to the superstars in an attempt to talk to space beings. They performed this using what was actually after that the largest broadcast telescope in the world, positioned at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan delivered their information to the M13 star cluster.
The message was actually written in binary code and consisted of relevant information regarding individual DNA. It additionally consisted of amounts of a human, the solar system and the Arecibo telescope. The idea was that if any sort of aliens were to receive the indicator as well as determine how to translate it, they would certainly know where it arised 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 message– if they are even out certainly there. The Arecibo information is actually only one of many messages aimed for e.t.s. We have actually likewise included messages on numerous spacecraft, like Pioneer and Voyager.
