.On November 16, 1974, people delivered their 1st information to the celebrities in a try to contact extraterrestrials. They did this using what was then the most extensive radio telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A team of researchers led by Frank Drake as well as Carl Sagan delivered their information to the M13 star cluster.
The message was written in binary code and also included info about individual DNA. It also consisted of bodies of an individual, the solar system and the Arecibo telescope. The concept was actually that if any sort of aliens were actually to obtain the sign and determine exactly how to decode it, they would certainly recognize where it came from.
Considering that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any type of M13 aliens to hear our message– if they are level there. The Arecibo notification is a single of many messages wanted for space beings. Our company have also included notifications on numerous space probe, including Trailblazer and also Voyager.
