.On November 16, 1974, human beings sent their very first message to the celebrities in an effort to call extraterrestrials. They did this utilizing what was at that point the largest broadcast telescope worldwide, located at the Arecibo Observatory in Puerto Rico. A group of scientists led through Frank Drake and also Carl Sagan sent their notification to the M13 galaxy.
The notification was actually filled in binary code as well as consisted of information concerning individual DNA. It additionally included bodies of a human, the planetary system and the Arecibo telescope. The concept was actually that if any type of invaders were to acquire the indicator as well as find out just how to decode it, they would understand where it came from.
Considering that M13 is actually 25,000 light-years away, it will 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 a single of several information meant for space beings. Our company have likewise featured notifications on several spacecraft, such as Trailblazer as well as Voyager.
