.On Nov 16, 1974, people sent their first information to the stars in an effort to speak to extraterrestrials. They did this using what was actually then the largest radio telescope worldwide, positioned at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and Carl Sagan delivered their notification to the M13 galaxy.
The information was written in binary code and had information concerning individual DNA. It likewise consisted of numbers of a human, the solar system and the Arecibo telescope. The idea was actually that if any kind of aliens were actually to get the sign and identify just how to decipher it, they would understand where it originated from.
Since M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any M13 invaders to hear our message– if they are actually flatten there certainly. The Arecibo message is actually a single of several messages intended for space beings. Our team have actually additionally included notifications on several spacecraft, like Trailblazer and Voyager.
