- New composite images made from NASA's Cassini spacecraft have provided a detailed global infrared views ever produced of Saturn's moon Enceladus.
- The data, used to build those images, provides strong evidence that the northern hemisphere of the moon has been resurfaced with ice from its interior.
- Cassini's Visible and Infrared Mapping Spectrometer (VIMS) collected light reflected off Saturn, its rings, and its 10 major icy moons -- light that is visible to humans as well as infrared light.
- VIMS then separated the light into its various wavelengths, information that tells scientists more about the makeup of the material reflecting it.
