Io’s Fire, Caught on Camera

Jupiter's third-largest moon is the most volcanically active object in the solar system.

NASA's New Horizons spacecraft took amazing images of an eruption on Io in 2007 when it traveled past Jupiter, and NASA just released them now. ​ Io's volcanoes can produce plumes that climb as high as 300 miles above the moon's surface.
