.On November 16, 1974, human beings sent their 1st notification to the celebrities in an effort to speak to extraterrestrials. They performed this using what was actually after that the most extensive radio telescope on the planet, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake as well as Carl Sagan delivered their information to the M13 galaxy.
The notification was actually filled in binary code and also consisted of information regarding individual DNA. It also featured numbers of an individual, the solar system and also the Arecibo telescope. The concept was actually that if any kind of aliens were actually to get the sign as well as determine how to decode it, they would understand where it came from.
Given that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any type of M13 invaders to hear our notification– if they are even out there certainly. The Arecibo notification is actually a single of many messages meant for space beings. We have additionally included notifications on many space probe, including Trailblazer and also Voyager.
