.On November 16, 1974, human beings sent their 1st message to the stars in an effort to contact extraterrestrials. They performed this utilizing what was then the most extensive radio telescope worldwide, situated at the Arecibo Observatory in Puerto Rico. A team of scientists led by Frank Drake and also Carl Sagan delivered their message to the M13 star cluster.
The information was written in binary code and also contained details concerning individual DNA. It additionally included numbers of an individual, the planetary system as well as the Arecibo telescope. The concept was that if any kind of aliens were to obtain the signal as well as identify exactly how to translate it, they will recognize where it came from.
Given that M13 is 25,000 light-years away, it is going to take 25,000 years for any type of M13 aliens to hear our information– if they are actually flatten certainly there. The Arecibo notification is actually only one of many information aimed for e.t.s. Our team have likewise consisted of messages on a number of spacecraft, like Leader and Voyager.
