A Venusian Landscape

Explanation: This computer generated view of a Venusian volcano was created using data from NASA's Magellan spacecraft . Magellan used its onboard radar to map the surface of Venus which is hidden from telescopic observations by a perpetual cloud cover. Using this radar data to provide three dimensional information, a computer was then able to produce this view of Maat Mons , a 5 mile high volcano, from a dramatic perspective. The colors used to render the surface are based on earlier color images transmitted by TV cameras on the Soviet Venera 13 and 14 Venus landers.
