Title:
Erupting Volcanoes on Io
Explanation:
Jupiter's moon Io has active volcanoes. The Voyager spacecraft [ http://www.jpl.nasa…] caught several erupting when they passed the energetic moon in 1979. In the above picture, several of Io's volcanoes [ http://antwrp.gsfc.…] are visible and one is seen actually erupting. Debris from this explosive event can be seen on the upper left of the photo, just beyond Io's edge. Io [ http://antwrp.gsfc.…]'s volcanism is thought to be caused by the large tidal distortions raised by Jupiter [ http://antwrp.gsfc.…], Europa [ http://antwrp.gsfc.…], and Ganymede [ http://antwrp.gsfc.…]. These tides stretch Io [ http://antwrp.gsfc.…], cause internal friction, and thus heat the interior. The hot interior then expands and forces its way out through volcanoes. Currently, the spacecraft Galileo [ http://antwrp.gsfc.…] is orbiting Jupiter [ http://antwrp.gsfc.…] and photographing Jupiter's Galilean moons [ http://antwrp.gsfc.…].
