The "Propellers" of the Rings (4) - HR (detail mgnf)

This magnified view illustrates the general orientation of the Propellers in Saturn's Rings, as they orbit around the Planet.

The two dashes of the Propeller are oriented in the direction of orbital motion. The "leading" dash is also slightly closer to Saturn; this "radial offset" is about 300 mt (about 1000 feet). The unseen moonlet lies in the center of the structure.

The grainy appearance of the image is due to magnification and the fact that the Propellers are very faint - just visible above the level of the back-ground noise. Consequently, the image enhancement procedures used to create this detail mgnf, have also enhanced the noise.
