.On Nov 16, 1974, humans sent their first notification to the superstars in an attempt to call extraterrestrials. They performed this utilizing what was actually after that the largest broadcast telescope on earth, positioned at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan sent their notification to the M13 galaxy.
The message was actually filled in binary code as well as included relevant information regarding human DNA. It additionally included numbers of a human, the solar system as well as the Arecibo telescope. The concept was that if any invaders were to get the sign and identify just how to decode it, they will recognize where it came from.
Given that M13 is 25,000 light-years away, it will take 25,000 years for any M13 aliens to hear our notification– if they are actually flatten there. The Arecibo notification is actually only one of many messages planned for e.t.s. Our experts have actually also featured messages on many space probe, including Pioneer and also Voyager.
