.On Nov 16, 1974, humans sent their 1st message to the superstars in a try to call extraterrestrials. They did this utilizing what was actually then the biggest radio telescope on earth, located at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake and also Carl Sagan delivered their notification to the M13 galaxy.
The notification was actually recorded binary code and also had relevant information about individual DNA. It likewise included numbers of an individual, the planetary system and the Arecibo telescope. The idea was that if any kind of aliens were to get the signal and also find out exactly how to translate it, they will know where it stemmed from.
Due to the fact that M13 is actually 25,000 light-years away, it will take 25,000 years for any sort of M13 aliens to hear our message– if they are even out certainly there. The Arecibo information is only one of numerous information aimed for space beings. Our experts have also consisted of information on numerous space probe, like Pioneer and also Voyager.
