.On November 16, 1974, people sent their initial message to the superstars in an attempt to call extraterrestrials. They performed this using what was after that the most extensive radio telescope around the world, located at the Arecibo Observatory in Puerto Rico. A group of researchers led by Frank Drake and Carl Sagan delivered their message to the M13 galaxy.
The notification was written in binary code and also contained relevant information about human DNA. It also featured numbers of a human, the solar system and the Arecibo telescope. The suggestion was actually that if any invaders were actually to acquire the indicator and also determine exactly how to decipher it, they will know where it came from.
Considering that M13 is actually 25,000 light-years away, it will definitely take 25,000 years for any type of M13 aliens to hear our notification– if they are actually flatten certainly there. The Arecibo information is a single of several information wanted for space beings. Our team have actually also consisted of messages on several space probe, including Leader and also Voyager.
