.On Nov 16, 1974, humans delivered their 1st notification to the superstars in an attempt to speak to space beings. They did this utilizing what was then the largest radio telescope on earth, found at the Arecibo Observatory in Puerto Rico. A team of experts led through Frank Drake and Carl Sagan sent their information to the M13 galaxy.
The notification was written in binary code and also included details regarding individual DNA. It likewise featured bodies of an individual, the solar system and the Arecibo telescope. The suggestion was actually that if any type of invaders were to obtain the indicator and also find out just how to translate it, they will 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 invaders to hear our information– if they are flatten there. The Arecibo information is actually just one of a number of information planned for extraterrestrials. We have also consisted of information on many spacecraft, like Trailblazer and also Voyager.
