.On Nov 16, 1974, humans sent their first information to the stars in an effort to contact extraterrestrials. They performed this using what was at that point the most extensive radio telescope on the planet, located at the Arecibo Observatory in Puerto Rico. A group of experts led through Frank Drake and Carl Sagan delivered their information to the M13 star cluster.
The notification was actually filled in binary code as well as included relevant information concerning human DNA. It additionally consisted of figures of an individual, the planetary system and the Arecibo telescope. The tip was that if any sort of invaders were to get the signal as well as determine how to translate it, they will know where it came from.
Given that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any sort of M13 aliens to hear our notification– if they are level certainly there. The Arecibo notification is a single of numerous information wanted for extraterrestrials. Our team have also featured messages on several space capsule, such as Pioneer and Voyager.
