This infrared image of Saturn’s rings was taken with the Cassini spacecraft wide-angle camera on August 18, 2013, using a special filter that only admits light polarized in one direction. Scientists can use these images to learn more about the nature of the particles that make up Saturn’s rings.
The view was acquired at a distance of approximately 712,000 miles (1.1 million kilometers) from Saturn. Image scale is 43 miles (68 kilometers) per pixel.
