  • Plumes

    Plumes of icy material shooting above the southern polar region of Saturn's moon Enceladus. Captured by the Cassini spacecraft in February, images like these are being analyzed by scientists seeking to explain how the plumes are produced. As reported in the journal Science on Friday, imaging scientists believe that the plumes are geysers erupting from pressurized subsurface reservoirs of liquid water above 32 degrees Fahrenheit (273 degrees Kelvin, 0 degrees Celsius). The monochrome view is shown here, along with a color-coded version on the right that reveals a fainter and much more extended portion of the plume.

  • Backlit plumes

    Recent Cassini images show the fountainlike plumes of fine spray that tower over Enceladus' south polar region. This image, backlit by the sun, was taken looking more or less broadside at "tiger stripe" fractures observed in earlier Enceladus images.
