Description

This is a digitally enhanced version of an image constructed from optical depth profiles of Saturn's rings, by NASA's Cassini spacecraft. The original NASA raw capture is in public domain.

To generate the raw NASA image, three simultaneous radio signals of 0.94, 3.6, and 13 centimeter wavelengths were sent from Cassini through the rings to Earth. The observed change of each signal as Cassini moved behind the rings profiled the distribution of ring material as a function of distance from Saturn (or an optical depth profile).

The simulated image was constructed from the measured optical depth profiles. Color is used to represent information about ring particle sizes in different regions based on the measured effects of the three radio signals. Purple color indicates regions where there is a lack of particles of size less than 2 inches. Green and blue shades indicate regions where there are particles smaller than 2 inches and 0.3 inch. The saturated broad white band is the densest region. All ring regions are thought to contain particles that are upto several feet across.

I have modified the original raw public-domain NASA image considerably to enhance the colors, beauty, balance and luminosity, in order to provide you a breathtaking, high quality, fine art print through this website. You may also want to check out the companion black & white (monochrome) version of this image I posted recently.
