.On November 16, 1974, humans sent their 1st information to the stars in an effort to talk to extraterrestrials. They did this using what was actually at that point the largest broadcast telescope in the world, situated at the Arecibo Observatory in Puerto Rico. A team of experts led by Frank Drake and Carl Sagan delivered their notification to the M13 galaxy.
The information was actually written in binary code and consisted of information concerning individual DNA. It additionally consisted of figures of a human, the planetary system and also the Arecibo telescope. The concept was actually that if any aliens were actually to receive the sign as well as identify just how to translate it, they will understand where it came from.
Due to the fact that M13 is 25,000 light-years away, it will certainly take 25,000 years for any type of M13 aliens to hear our message– if they are actually flatten there certainly. The Arecibo information is just one of many messages planned for extraterrestrials. Our experts have also consisted of messages on many space probe, like Leader and Voyager.
