.On Nov 16, 1974, people sent their very first notification to the stars in an effort to call space beings. They did this utilizing what was actually at that point the biggest broadcast telescope on earth, situated at the Arecibo Observatory in Puerto Rico. A team of experts led by Frank Drake and Carl Sagan sent their message to the M13 galaxy.
The notification was actually recorded binary code and included relevant information regarding individual DNA. It also included numbers of a human, the solar system and also the Arecibo telescope. The idea was that if any kind of aliens were actually to receive the indicator as well as identify exactly how to decode it, they would certainly know where it came from.
Since M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any M13 aliens to hear our message– if they are actually flatten there. The Arecibo information is actually only one of numerous notifications planned for space beings. Our company have likewise included notifications on several spacecraft, including Pioneer as well as Voyager.
