.On November 16, 1974, humans delivered their very first notification to the stars in an attempt to speak to extraterrestrials. They did this using what was then the largest radio telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A group of scientists led by Frank Drake and also Carl Sagan sent their notification to the M13 star cluster.
The message was actually filled in binary code and contained info regarding individual DNA. It additionally consisted of bodies of an individual, the solar system and also the Arecibo telescope. The tip was actually that if any invaders were to receive the indicator and also determine how to decode it, they would certainly recognize where it arised from.
Since M13 is actually 25,000 light-years away, it is going to take 25,000 years for any sort of M13 invaders to hear our message– if they are actually flatten certainly there. The Arecibo information is just one of a number of notifications meant for extraterrestrials. Our company have also consisted of messages on a number of space probe, including Leader and also Voyager.
