Cassini Reveals a Spirals in Saturn’s D Ring

In this picture NASA’s Cassini Spacecraft reveals a turn structures in Saturn’s D ring.

Although a D ring of Saturn is so skinny that it’s hardly conspicuous compared to a rest of a ring system, it still displays structures seen in other Saturnian rings. Here a turn structures in a D ring are on display.

The D ring spirals, detected in Cassini images, are believed to be due to a diverge in a ring combined in a early 1980s. The accurate resource stays a theme of systematic debate. Over a march of a Cassini mission, scientists have been means to observe a turn circuitous ever some-more firmly as it evolves.

(The splendid specks and gloomy straight streaks are merely picture artifacts. The processes typically employed to mislay these artifacts would also have degraded a artistic sum of a D ring that are manifest here.)

This perspective looks toward a sunlit side of a rings from about 22 degrees above a ringplane. The picture was taken in manifest light with a Cassini booster narrow-angle camera on Jul 6, 2013.

The perspective was acquired during a stretch of approximately 350,000 miles (563,000 kilometers) from Saturn and during a Sun-Saturn-spacecraft, or phase, angle of 131 degrees. Image scale is 2.1 miles (3.4 kilometers) per pixel.
