.On November 16, 1974, human beings delivered their 1st information to the stars in a try to speak to extraterrestrials. They did this utilizing what was after that the largest radio telescope on earth, situated at the Arecibo Observatory in Puerto Rico. A group of experts led through Frank Drake and Carl Sagan sent their notification to the M13 galaxy.
The notification was actually filled in binary code and also contained information concerning individual DNA. It also included figures of an individual, the solar system and the Arecibo telescope. The concept was that if any sort of aliens were to acquire the sign and identify just how to decode it, they would know where it originated from.
Given that M13 is 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 even out there. The Arecibo notification is just one of many information intended for e.t.s. We have likewise included notifications on several space capsule, including Leader and Voyager.
