Saturn’s rings seem to hook as they pass behind a planet’s darkened prong due to refraction by Saturn’s top atmosphere.
The outcome is a same as that seen in an progressing Cassini perspective (see PIA20491), solely this perspective looks toward a dark face of a rings, while a progressing picture noticed a rings’ sunlit side.
The disproportion in enlightenment brings out some conspicuous differences. The A ring is most darker here, on a rings’ dark face, given a incomparable particles essentially simulate light behind toward a object (and divided from Cassini’s cameras in this view). The slight F ring (at bottom), that was gloomy in a progressing image, appears brighter than all of a other rings here, interjection to a little dirt that is prevalent within that ring. Small dirt tends to separate light brazen (meaning tighten to a strange instruction of travel), creation it seem splendid when backlit. (A identical outcome has tormented many a motorist with a dry windshield when pushing toward a sun.)
This perspective looks toward a unilluminated side of a rings from about 19 degrees next a ring plane. The picture was taken in red light with a Cassini booster narrow-angle camera on Jul 24, 2016.
The perspective was acquired during a stretch of approximately 527,000 miles (848,000 kilometers) from Saturn and during a sun-Saturn-spacecraft, or phase, angle of 169 degrees. Image scale is 3 miles (5 kilometers) per pixel.
