Space is full of explosions. Volcanoes abound in our solar system, and some bodies in space (besides Earth) are hotbeds of geological activity.
Exploring our solar system’s active and inactive volcanoes could help us better understand how planets and moons formed into the celestial bodies we know today.
Here are 7 surprising spots we’ve found volcanoes in the Solar System:
7. Eruptions on Io
Jupiter’s moon, Io, is the most geologically active body in the solar system. This image, taken by NASA’s New Horizons spacecraft in 2007, shows a 180-mile high plume rising above one of its volcanoes.
Our sister planet is home to at least 1,600 major volcanoes, and some might still be active today. So far only inactive ones have been spotted, but upcoming missions will capture new views of Venus’ topography.
Earth’s moon has signs of once-active volcanoes that can be seen on its surface. This patch, informally called Ina, is the remains of volcanic activity on the Moon, and was first discovered during the Apollo 15 mission in 1971.
