The volcano, Sif Mons, on Venus shows evidence for past activity in the form of a solidified lava flow that shows up in this image as a brighter streak down the sides of its cone. Planetary scientists would like to know if such eruptions are taking place today. This 3-D view of the surface of Venus was produced in a computer using radar data collected by NASA's Magellan spaceprobe from orbit, in the early 1990s.
