In 1974, during a ceremony to commemorate the renovation of the Arecibo radio telescope in Puerto Rico, data collected by Carl Sagan and his colleagues was transmitted into space via radio waves. This was the strongest message ever sent by humans into space. The message was sent directly to a star cluster about 25,000 light-years from Earth and contained visual messages.
