Two masters of their craft are caught at work shaping Saturn's rings captured by NASA's Cassini spacecraft. Pandora (upper right) sculpts the F ring. Meanwhile, Daphnis is busy holding open the Keeler gap (bottom center).
NASA's Cassini orbiter shows Saturn's main rings, seen here on their 'lit' face, appear much darker than normal. That's because they tend to scatter light back toward its source -- in this case, the Sun.
NASA's Cassini orbiter shows that Tethys appears to be peeking out from behind Rhea, watching the watcher. Scientists believe that Tethys' surprisingly high albedo is due to the water ice jets emerging from its neighbor, Enceladus.
NASA's Cassini orbiter shows that Enceladus (visible in the lower-left corner of the image) is but a speck before enormous Saturn, but even a small moon can generate big waves of excitement throughout the scientific community.
NASA's Cassini orbiter shows Saturn is circled by its rings (nearly edge-on in this image), as well as by the moons Tethys (the large bright body near the lower right corner) and Mimas (seen as a slight crescent against Saturn's disk above the rings).
Nature is an artist, and this time she seems to have let her paints swirl together a bit. What the viewer might perceive to be Saturn's surface captured by NASA's Cassini orbiter is really just the tops of its uppermost cloud layers.
A new day dawns on Saturn as the part of the planet is seen emerging once more into the Sun's light by NASA's Cassini orbiter. With an estimated rotation period of 10 hours and 40 minutes, Saturn's days and nights are much shorter than those on Earth.
This set of global, color mosaics of Saturn's moon Dione taken by NASA's Cassini spacecraft during its first ten years exploring the Saturn system; obvious feature on the maps is the difference in color and brightness between the two hemispheres.
The view was obtained during NASA's Cassini orbiter's flyby on July 24, 2012, also called the 'T85' flyby by the Cassini team. This was the most intense specular reflection that Cassini had seen to date.
The moons visible in this image from NASA's Cassini spacecraft, Pandora and Atlas, are quite small by astronomical standards, but the rings are also enormous. From one side of the planet to the other, the A ring stretches over 170,000 miles (270,000 km).
