.On November 16, 1974, humans delivered their first notification to the celebrities in a try to get in touch with space beings. They performed this utilizing what was at that point the most extensive radio telescope on the planet, situated at the Arecibo Observatory in Puerto Rico. A team of scientists led through Frank Drake and also Carl Sagan delivered their notification to the M13 galaxy.
The message was written in binary code and contained details regarding human DNA. It also featured numbers of a human, the planetary system as well as the Arecibo telescope. The idea was actually that if any kind of invaders were to get the sign and figure out how to decipher it, they will know where it arised from.
Given that M13 is 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 notification is actually just one of several messages intended for space beings. We have likewise consisted of notifications on many spacecraft, like Leader and also Voyager.
