.On November 16, 1974, humans delivered their very first message to the stars in a try to talk to extraterrestrials. They did this using what was actually then the most extensive broadcast telescope in the world, found at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan sent their message to the M13 galaxy.
The notification was recorded binary code and consisted of relevant information about individual DNA. It also included figures of an individual, the solar system and the Arecibo telescope. The suggestion was actually that if any type of aliens were actually to obtain the signal and find out just how to decode it, they will understand where it stemmed from.
Given that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any sort of M13 invaders to hear our information– if they are actually level there. The Arecibo message is actually only one of many messages planned for space beings. Our experts have likewise consisted of information on many space probe, such as Pioneer and Voyager.
