volcanic euruption on Io seen from NASA’s New Horizons probe

Check out Tvashtar volcano on Io seen spewing molten material into space, as seen from New Horizons probe in 2007. Io experiences massive tidal forces from Jupiter’s gravity and this kind of volcanic eruption is not uncommon for Jovian moons. For a sense of scale, the volcanic plume is about 330 Km in altitude. New Horizon was built by John Hopkins Applied Phyisics Lab for a mission to Pluto. This photo was taken when it flew past Jupiter for a slingshot course correction towards Pluto.
