.On November 16, 1974, people delivered their first message to the stars in an attempt to contact e.t.s. They did this using what was actually after that the largest broadcast telescope on the planet, situated at the Arecibo Observatory in Puerto Rico. A group of researchers led by Frank Drake as well as Carl Sagan sent their information to the M13 galaxy.
The message was actually filled in binary code and contained details about individual DNA. It additionally consisted of bodies of a human, the solar system and the Arecibo telescope. The idea was actually that if any type of invaders were to obtain the sign and also determine just how to decipher it, they would understand where it originated from.
Considering that M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any M13 aliens to hear our notification– if they are actually even out there. The Arecibo information is actually only one of many information planned for space beings. We have additionally featured information on a number of space probe, such as Leader and Voyager.
