And a tiny little “ring shepherd” moon can be seen directly above/left of Dione.

We have had our share of global Saturn portraits, but I do believe this is the first taken where the rings are unlit by the sun. An interesting alternate view provided by Gordan Ugarkovic (as usual).

This composite has been kicked around a bunch on unmannedspaceflight.com. Contained within it are two separate images taken by the Cassini mission at nearly the same time but different exposures. Looking at this scene with human eyes, the big difference would likely be that the geysers would not be blown out and would look more like a multiple of gentle hazes spewing upward. The other big difference would be that you were somehow on a mission to Saturn and not browsing the web.

Above are the two original exposures. These were merely combined with a photo editing tool. The geyser haze was blurred in areas to clean out compression artifacts and the color was artistically added by Gordan Ugarkovic. While the color is artificially generated, it does accurately reflect the same overall appearance of most natural light images of Titan.

Prometheus is the small moon that shepherds Saturn’s outer “F” ring and causes those crazy waves in the particles that make up the ring itself. The phenomenon has been the theme of at least 3 different animations here on wanderingspace.net. The image above is what that small moon in those animations looks like from 60,000 km taken by Cassini on Dec 26, 2009.

Recent observations of Saturn’s rings from Cassini reveal some vertical structure to the rings. Shown here are disturbances caused by Daphnis, a small moonlet that orbits within the Keeler Gap of the rings. We have seen much of these kinds of disturbances in the rings from tiny moonlets, but the Saturninan equinox finally provides us with an angle of sunlight that reveals such structures from the long shadows they cast. The tallest shadow seen at right is Daphnis itself.

Some recent posts from Gordan Ugarkovic. The first is just gorgeous, the second featuring Prometheus and Pan in the gaps, the third is also just real pretty and the 4th is two sides of Enceladus. The 2nd and 4th of these images are false color which we publish less often, but these were just too nice to deny.

Saturn in near infrared filter. Taken late March 2009.

Yes, another movie of Prometheus disturbing Saturn’s rings. This is the longest clip and includes the most ring swinging action for your money. This version has been cropped and reduced down from the original. See here for a larger, wider view of the same animation (2M gif).

Another by Gordan Ugarkovic. Will post a wallpaper version later. Too gorgeous.

Gordan’s reworking of images taken October of 2005. Strikingly gorgeous. I think we have at least one impressive dramatic color image of each of Saturn’s major moons with Saturn or its rings as backdrop at this point.

1. Mimas
2. Enceladus
3. Dione
4. Tethys (this one)
5. Rhea
6. Titan

From the raw images of the Cassini mission. This is Saturn’s tiny moon Prometheus causing a disturbance in some ring particles. Nothing really new to be said here as we have seen this featured in a few animations posted here before. This is just a nice image of that phenomenon with the addition of a nice glaringly over-exposed Prometheus.

Another Ugarkovic Beauty. Visible in the image are also Enceladus, Epimetheus and Mimas.
