New Horizons flashback: Tvashtar volcano erupting on Io

A composite of pictures taken by New Horizons when it flew by Jupiter (and its moons) in 2007

  • Io

    With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io's interior as it is pulled between Jupiter and the other Galilean satellites—Europa, Ganymede and Callisto. Several volcanoes produce plumes of sulfur and sulfur dioxide that climb as high as 500 km (300 mi) above the surface.
