 Hemispheric view of Venus, centered at 90 degrees east longitude. The image was produced from a mosaic of images from the Magellan Mission (1990-1994). The image is color-coded to represent elevations, with the colder (bluish) colors representing lower elevations than the warmer (tannish-red to white) colors representing higher elevations.
