.On November 16, 1974, human beings sent their first notification to the superstars in an attempt to consult with extraterrestrials. They performed this utilizing what was actually at that point the largest broadcast telescope on the planet, positioned at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake as well as Carl Sagan delivered their information to the M13 star cluster.
The notification was written in binary code as well as contained details concerning individual DNA. It also featured amounts of a human, the planetary system and also the Arecibo telescope. The idea was actually that if any type of invaders were actually to acquire the indicator as well as find out just how to decipher it, they would certainly know where it stemmed from.
Considering that M13 is actually 25,000 light-years away, it will take 25,000 years for any type of M13 invaders to hear our notification– if they are flatten certainly there. The Arecibo message is only one of a number of information planned for space beings. We have actually likewise featured information on a number of spacecraft, such as Leader as well as Voyager.
