Here, the Cassini spacecraft looks into Saturn's clouds using a spectral filter sensitive to absorption by methane. Light that reaches down to depths where methane is prevalent gets absorbed. Regions of the planet devoid of the clouds and hazes that can reflect this light back to the camera appear relatively dark. Thus, the bright areas in these images represent hazes and clouds high in the atmosphere.</p><p>Because the range of wavelengths for this filter is narrow, and because most of this light is absorbed by Saturn, the planet's disk is inherently faint and the exposures required are rather long. The rings do not strongly absorb at these wavelengths, and so they reflect more light and are overexposed compared to the atmosphere.</p><p>This view looks toward the sunlit side of the rings from about 6 degrees below the ringplane.

The Cassini Division is visible at lower left.</p><p>The image was taken in visible red light with the Cassini spacecraft narrow-angle camera on Oct. 21, 2007. The view was obtained at a distance of approximately 1.7 million kilometers (1 million miles) from Saturn and at a Sun-ring-spacecraft, or phase, angle of 68 degrees. Image scale is about 11 kilometers (7 miles) per pixel in the radial, or outward from Saturn, direction.</p><p>The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.
