Credit: NASA/JPL/Space Science Institute Plumes of icy material extend above the southern polar region of Saturn's moon Enceladus 28 Plumes of icy material extend above the southern polar region of Saturn's moon Enceladus as imaged by the Cassini spacecraft in February 2005. The monochrome view is presented along with a color-coded version on the right. The latter reveals a fainter and much more extended plume component. Wikimedia Commons 29 The model shows how proposed underground reservoirs of pressurized liquid water above 273 degrees Kelvin (0 degrees Celsius) could fuel geysers that send jets of icy material into the skies above the moon's south pole. Some combination of internal radioactive decay and tidal heating is implicated as the source of the heat creating the liquid reservoirs. However, it is not yet clear how the deep interior of Enceladus functions, nor whether the moon is fully diferentiated (separated into layers, with rock at the center and ice outside).
