.On Nov 16, 1974, human beings sent their first message to the stars in an effort to consult with e.t.s. They performed this using what was then the most extensive broadcast telescope on earth, found 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 message was actually recorded binary code and also contained relevant information about human DNA. It also included numbers of an individual, the solar system and the Arecibo telescope. The concept was that if any kind of aliens were actually to receive the sign and also find out how to decipher it, they would certainly know where it arised from.
Considering that M13 is 25,000 light-years away, it will take 25,000 years for any kind of M13 aliens to hear our message– if they are actually level there certainly. The Arecibo notification is just one of a number of information aimed for e.t.s. We have actually likewise included information on several spacecraft, such as Pioneer and Voyager.
