This color image of Io was created by combining the color channels of the low resolution USGS Voyager controlled color mosaic with Tayfun Oner's high resolution Galileo mosaic. The brown, orange areas are probably covered by sulphur or a mixture containing sulphur. The light areas may be sulphur dioxide snow and the pock-marks are mostly volcanic calderas up to 200 kilometers (124 miles) across. Mountainous regions exist near both poles, with some features rising 8 kilometers (5 miles) or more above their surroundings. (Courtesy A.Tayfun Oner)
