Volcanoes on Venus

Volcanoes on Venus

. Radar-reflectivity and topographic altitudes from Magellan have been combined to construct this three-dimensional perspective view of the surface of Venus. Lava flows extend for hundreds of thousands of meters in the foreground at the base of the volcano Sapas Mons (center). Another volcano, Maat Mons, appears on the horizon; a close-up view of Maat Mons was shown in Fig. 2.27. The volcanic origin of these peaks is suggested by the fiery orange and yellow colors, but there can be no fires on Venus without oxygen. The artificial tints are based on color images taken by the Veneras 13 and 14 landers, simulating the color of sunlight that filters through the thick atmosphere. Sapas is named after a Phoenician goddess, Maat is the name of an ancient Egyptian goddess of truth and justice, and Mons is the Latin term for “mountain”. (Courtesy of JPL and NASA.)
