Arecibo message

Visualisation of a binary message transmitted from Earth to the M13 star cluster on 16 November 1974 using the Arecibo radio telescope. In addition to some binary number clues, the diagram illustrates a DNA molecule, a human stick figure, our solar system and the radio telescope itself. Any reply to this message will take at least thousands of years to return.
