.On Nov 16, 1974, human beings delivered their very first notification to the superstars in an attempt to get in touch with extraterrestrials. They did this utilizing what was actually at that point the largest radio telescope on the planet, located at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan delivered their notification to the M13 galaxy.
The notification was written in binary code and also had relevant information about human DNA. It likewise consisted of figures of a human, the solar system and also the Arecibo telescope. The concept was actually that if any kind of invaders were to acquire the indicator and also identify just how to decode it, they will understand where it originated from.
Given that M13 is actually 25,000 light-years away, it will take 25,000 years for any kind of M13 aliens to hear our information– if they are actually even out there. The Arecibo message is only one of several notifications meant for e.t.s. Our company have actually likewise included messages on several spacecraft, including Pioneer and Voyager.
