Mars, photographed by astronomer Edward Emerson Barnard with the Yerkes Observatory 40-inch refractor telescope, 1909. Lower right: Region of Mare Cimmerium, October 6, 4:15 (UT); Others: Syrtus Major Region, September 29, 5h (UT). Each exposure is the superposition of three to five original frames. This reduces grain and brings out fine halftones.
