.On Nov 16, 1974, human beings delivered their very first message to the stars in an effort to get in touch with extraterrestrials. They did this utilizing what was then the most extensive broadcast telescope worldwide, located 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 information was actually recorded binary code and also had relevant information about human DNA. It also included bodies of a human, the solar system as well as the Arecibo telescope. The concept was that if any kind of invaders were actually to obtain the sign as well as figure out how to translate it, they would certainly recognize where it came from.
Considering that M13 is 25,000 light-years away, it will definitely take 25,000 years for any type of M13 aliens to hear our message– if they are flatten there. The Arecibo message is a single of many messages wanted for e.t.s. Our experts have also consisted of information on numerous spacecraft, including Pioneer as well as Voyager.
