The Arecibo Message

 

Globular cluster M13 was selected in 1974 as target for one of the first radio messages addressed to possible extra-terrestrial intelligent races, and sent by the big radio telescope of the Arecibo Observatory. Of course, this message will take about 23,000 years to reach the cluster. It included representations of the fundamental chemicals of life, the formula for DNA, a crude diagram of our solar system, and simple pictures of a human being and the Arecibo telescope.
