.On Nov 16, 1974, humans delivered their very first message to the superstars in an effort to contact extraterrestrials. They did this using what was then the largest radio telescope on the planet, located at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan delivered their notification to the M13 star cluster.
The information was actually recorded binary code and also included details concerning human DNA. It additionally consisted of bodies of an individual, the solar system as well as the Arecibo telescope. The tip was that if any type of invaders were to get the signal and figure out just how to translate it, they would understand where it originated from.
Since M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any kind of M13 aliens to hear our message– if they are even out certainly there. The Arecibo notification is only one of a number of information intended for space beings. Our company have additionally consisted of notifications on many space probe, including Pioneer and also Voyager.
