.On November 16, 1974, humans delivered their 1st notification to the superstars in an effort to get in touch with space beings. They performed this utilizing what was at that point the most extensive radio telescope in the world, situated at the Arecibo Observatory in Puerto Rico. A group of experts led by Frank Drake as well as Carl Sagan sent their information to the M13 galaxy.
The notification was written in binary code and contained info about individual DNA. It also featured figures of an individual, the planetary system and the Arecibo telescope. The idea was actually that if any type of aliens were actually to get the indicator as well as identify exactly how to decode it, they would understand where it arised from.
Considering that M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any kind of M13 aliens to hear our notification– if they are actually even out there. The Arecibo information is actually a single of several messages wanted for e.t.s. Our team have also included information on several space capsule, such as Pioneer and Voyager.
