Infrared Eye Yields New Spectral Map

A CLOSER LOOK

The false-color image at right shows spectral mapping of Saturn's A, B and C rings, captured by Cassini's Visible and Infrared Mapping Spectrometer (VIMS). It displays an infrared view of the rings, rather than an image in visible light. The blue-green areas are the regions with the purest water ice and/or largest grain size (primarily the A and B rings), while the reddish color indicates increasing amounts of non-icy material and/or smaller grain sizes (primarily in the C ring and Cassini Division). At left, the same image is overlaid on a natural-color mosaic of Saturn taken by Cassini's Imaging Science Subsystem. https://photojournal.jpl.nasa.gov/catalog/PIA23170
