This composite image shows Saturn’s main rings, the F ring, and its shepherd satellites: the narrow F ring is located just outside of the outer edge of the main rings; slightly above and to the left of the center of the image are the shepherd satellites Prometheus (inner orbit) and Pandora (outer orbit).

This view from Cassini looks toward Dione, with giant Saturn and its rings in the background, just prior to the mission’s final close approach to the moon on August 17. The view was acquired at distances ranging from approximately 106,000 miles (170,000 km) to 39,000 miles (63,000 km) from the icy moon and at a Sun-Dione-spacecraft, or phase, angle of 35 degrees. At lower right is the large, multi-ringed impact basin Evander, which is about 220 miles (350 km) wide. The canyons of Padua Chasma, features that form part of Dione’s bright, wispy terrain, reach into the darkness at left. Scientists combined nine visible light images to create this mosaic view: eight from Cassini’s narrow-angle camera and one from the wide-angle camera, which fills in an area at lower left. The scene is an orthographic projection centered on terrain at 0.2 degrees north latitude, 179 degrees west longitude on Dione. An orthographic view is most like the view seen by a distant observer looking through a telescope. North on Dione is up. Image credit: NASA / JPL-Caltech / Space Science Institute.

This artist’s concept of a young solar system shows gas giants forming first, while the gas nebula is present. Prof Martin Duncan and co-authors used computer simulations to nail down how Jupiter and Saturn evolved in our own Solar System. These calculations show that the cores of gas giants likely formed by gradually accumulating a population of ‘planetary pebbles’ - icy objects about a foot in diameter.

$This image from NASA’s Cassini spacecraft shows a part of Dione’s surface that is covered by linear, curving features, called chasmata. The Voyager spacecrafts observed Dione in 1980 showing a complex surface structure, with wispy features on its trailing hemisphere. The nature of these features was unclear until 2004, when the Cassini spacecraft showed that they weren’t surface deposits of frost, as some had suspected, but rather a pattern of bright icy cliffs among myriad fractures. One possibility is that this stress pattern may be related to Dione’s orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione. Cassini obtained the image with its narrow-angle camera on April 11, 2015. The view was acquired at a distance of 68,000 miles (110,000 km) from Dione. North on Dione is up.

Reddish streaks cut across the surface of Tethys in this image. The streaks are narrow, curved lines on the moon’s surface, only a few miles wide but several hundred miles long. The yellowish tones on the left side of the view are a result of alteration of the moon’s surface by high-energy particles from Saturn’s magnetosphere. This particle radiation slams into the moon’s trailing hemisphere, modifying it chemically and changing its appearance in enhanced-color views like this one. The area of Tethys shown here is centered on 30 degrees north latitude, 187 degrees west longitude, and measures 305 by 258 miles (490 by 415 km) across. The original color images were obtained at a resolution of about 2,300 feet (700 m) per pixel on April 11, 2015. Image credit: NASA / JPL-Caltech / Space Science Institute.
