LESSON 2 · Grand Tour of the Solar System
Venus's Volcanic Surface
Venus is covered in volcanic features unlike anything on Earth. Over 1,600 major volcanoes dot its surface, alongside vast lava plains, pancake-shaped domes, and ring-like structures called coronae. The whole surface seems to have been repaved by volcanism roughly 500 million years ago.
Data from the Magellan orbiter and Europe's Venus Express even suggest some volcanoes may still be active. Shifting sulfur dioxide levels and possible infrared hotspots hint at ongoing eruptions — which would put Venus alongside Earth and Jupiter's moon Io as a volcanically active world.
