.On November 16, 1974, human beings sent their very first notification to the celebrities in an effort to call extraterrestrials. They performed this using what was actually at that point the biggest radio telescope around the world, positioned at the Arecibo Observatory in Puerto Rico. A team of researchers led by Frank Drake as well as Carl Sagan delivered their message to the M13 star cluster.
The notification was actually recorded binary code and also contained information regarding human DNA. It also included numbers of an individual, the solar system as well as the Arecibo telescope. The concept was actually that if any sort of invaders were actually to receive the indicator as well as find out exactly how to decode it, they would certainly know where it came from.
Considering that M13 is 25,000 light-years away, it will take 25,000 years for any type of M13 invaders to hear our notification– if they are actually level certainly there. The Arecibo message is actually just one of many information planned for space beings. Our company have actually likewise included information on a number of spacecraft, such as Trailblazer as well as Voyager.
