 An active eruption at the volcanic area called Tvashtar Catena.
 This diagram shows current scientific ideas about the role of sulfur in volcanoes on Io. Sulfur gas is thrown out of the hot vents (green arrow) and lands on the cold surface, where the sulfur atoms rearrange into molecules of three or four atoms, which give the surface a red colour. Eventually, the atoms rearrange into their most stable configuration, rings of eight atoms, which form ordinary pale yellow sulfur.
