.On Nov 16, 1974, humans sent their initial message to the celebrities in an effort to get in touch with e.t.s. They performed this using what was at that point the biggest broadcast telescope worldwide, located at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and also Carl Sagan delivered their information to the M13 star cluster.
The notification was actually recorded binary code and consisted of relevant information about individual DNA. It likewise consisted of figures of a human, the planetary system and also the Arecibo telescope. The suggestion was that if any invaders were to obtain the signal as well as find out just how to decipher it, they would certainly recognize where it arised from.
Since M13 is actually 25,000 light-years away, it is going to take 25,000 years for any kind of M13 aliens to hear our information– if they are actually level there. The Arecibo message is a single of several messages planned for extraterrestrials. Our team have likewise included messages on numerous spacecraft, such as Leader and also Voyager.
