.On November 16, 1974, people sent their 1st information to the stars in an attempt to get in touch with e.t.s. They did this utilizing what was actually then the most extensive broadcast telescope on earth, found at the Arecibo Observatory in Puerto Rico. A group of researchers led through Frank Drake and Carl Sagan sent their notification to the M13 galaxy.
The information was actually filled in binary code as well as contained information regarding human DNA. It likewise featured figures of a human, the solar system and also the Arecibo telescope. The idea was actually that if any type of invaders were to obtain the sign and determine how to translate it, they will understand where it came from.
Considering that M13 is 25,000 light-years away, it will take 25,000 years for any sort of M13 invaders to hear our notification– if they are actually flatten certainly there. The Arecibo notification is actually just one of a number of messages wanted for extraterrestrials. Our experts have likewise consisted of information on numerous spacecraft, such as Trailblazer and also Voyager.
