.On Nov 16, 1974, humans sent their initial notification to the superstars in an effort to consult with space beings. They performed this using what was after that the biggest broadcast telescope worldwide, located at the Arecibo Observatory in Puerto Rico. A group of experts led by Frank Drake and also Carl Sagan sent their message to the M13 galaxy.
The notification was recorded binary code and consisted of info regarding individual DNA. It also featured bodies of an individual, the solar system and the Arecibo telescope. The suggestion was that if any sort of invaders were actually to receive the signal and also determine just how to translate it, they will recognize where it arised from.
Given that M13 is 25,000 light-years away, it is going to take 25,000 years for any kind of M13 invaders to hear our message– if they are actually even out there certainly. The Arecibo information is actually a single of several notifications aimed for space beings. Our team have actually also consisted of notifications on a number of spacecraft, including Pioneer and also Voyager.
