The opaque veil of Venus was lifted by JPL's Magellan spacecraft during its 1990-1994 orbital mission. Venus glitters brightly in the night sky, but its dense cloud cover obscures the surface. The imaging radar on board Magellan penetrated the sulphuric-acid clouds. This three-dimensional perspective view shows the volcanoes Gula Mons (right) and Sif Mons (left).
