.On Nov 16, 1974, humans delivered their very first message to the superstars in an attempt to consult with space beings. They performed this utilizing what was then the biggest broadcast telescope worldwide, situated at the Arecibo Observatory in Puerto Rico. A team of researchers led through Frank Drake and also Carl Sagan delivered their notification to the M13 galaxy.
The information was actually written in binary code as well as contained relevant information concerning individual DNA. It likewise included numbers of an individual, the planetary system and also the Arecibo telescope. The idea was that if any invaders were to obtain the indicator and figure out exactly how to decode it, they will understand where it originated from.
Due to the fact that M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any kind of M13 invaders to hear our notification– if they are level certainly there. The Arecibo notification is only one of many information aimed for e.t.s. Our experts have actually also consisted of notifications on several space capsule, including Pioneer as well as Voyager.
