| On March 16, 2005, the Jet Propulsion Laboratories anounced that the spacecraft Cassini found an atmosphere on Enceladus. One of Saturn's other moons, Titan is thought to be the only moon in the solar system with a significant atmosphere. Enceladus is not massive enough to hold on to an atmosphere for very long so the presence of an atmosphere means that gasses are constantly being produced by the moon itself. Scientists believe the atmosphere is the result of volcanic activity and/or geysers. The surface of Enceladus is mostly made of ice. The volcanoes are believed to use this ice as its magma. |
