Cartão Seeking Intelligent Life in the Milky Way Card

A radio telescope surveys the heavens, listening to sounds from space sent by intelligent beings far away. Any such signals will probably originate from another planet within the Milky Way galaxy. Shown here is a planet with clear signs of a technologically advanced civilization: lights on the dark side of the planet in a uniform pattern unlikely to have been made by natural processes. From a mixed media painting created for Sky and Telescope magazine.
