SPACE — On November 16, 1974, humans sent their first message to the stars in an attempt to contact extraterrestrials. They did so using the world’s largest radio telescope, located at the Arecibo Observatory in Puerto Rico.
A group of scientists led by Frank Drake and Carl Sagan sent their message to the M13 star cluster. The message is written in binary code and contains information about human DNA.
It also includes images of humans, the solar system, and the Arecibo telescope. The idea is that if aliens receive the signal and figure out how to decode it, they will know where it comes from.

Since M13 is 25,000 light years away, it would take 25,000 years for the M13 aliens to hear our message, if they are out there. Arecibo’s message is just one of several aimed at extraterrestrials. They also included messages on several spacecraft, such as Pioneer and Voyager. Source: Space.com
