Spoke Set
June 5, 2007

This Cassini spacecraft view shows a group of more than a dozen spokes in Saturn's outer B ring. The B ring displays the azimuthal asymmetry, or variation with longitude around the planet, that is characteristic of the spoke-forming region.

The large spoke feature above center -- most likely a grouping of multiple spokes -- is about 5,000 kilometers (3,100 miles) long and 2,000 kilometers (1,200 miles) wide.

Left of center, two dark gaps mark the Cassini Division (4,800 kilometers, or 2,980 miles wide).

This view looks toward the unilluminated side of the rings from about 9 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 28, 2007 at a distance of approximately 1.6 million kilometers (1 million miles) from Saturn. Image scale is 9 kilometers (6 miles) per pixel.

The Crater Gradient
June 6, 2007

The Cassini spacecraft investigates the craters and deep valleys on Dione during a close approach in April 2007.

Significant variations in the density of impact craters on the surface of Dione can be seen here, with more craters seen on the right side of this mosaic (on Dione's sub-Saturn hemisphere) than on the left (on Dione's anti-Saturn hemisphere). The southern end of the bright Palatine Linea fracture system can be seen near the bottom of the mosaic. Along the terminator, at lower left, part of a large impact basin can be seen.

The mosaic is an orthographic projection centered at 33 degrees South, 74 degrees West, over the southern part of Dione's leading hemisphere. An orthographic view is most like the view seen by a distant observer looking through a telescope. North on Dione (1,126 kilometers, or 700 miles across) is up and rotated 6 degrees to the right.

The monochrome view uses a combination of images taken with spectral filters sensitive to wavelengths of light centered at 338, 568 and 930 nanometers.

The images in this mosaic were taken with the Cassini spacecraft narrow-angle camera on April 24, 2007 at a distance of approximately 121,000 kilometers (75,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 55 degrees. Image scale is 723 meters (2,371 feet) per pixel.

Difference on the Dark Side
June 11, 2007

Saturn's A ring displays a marked asymmetry in brightness between the region nearer to the Cassini spacecraft and the region farther from it. The A ring is the broad, bright section of the rings outside of the dark B ring. The asymmetry may help scientists understand various properties of the rings, such as the sizes of the particles and their arrangement into clumps.

The rings' dark shadows hug Saturn's northern hemisphere.

This view looks toward the unilluminated side of the rings from about 7 degrees above the ringplane. The planet is overexposed in this observation, which was designed to capture details in the rings.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on May 14, 2007 at a distance of approximately 1.8 million kilometers (1.1 million miles) from Saturn. Image scale is 101 kilometers (63 miles) per pixel.

Nightside Vista
July 12, 2007

Graceful giant Saturn poses with a few of the small worlds it holds close. From this viewpoint the Cassini spacecraft can see across the entirety of the planet's shadow on the rings, to where the ringplane emerges once again into sunlight.

Tethys (1,071 kilometers, or 665 miles across) shines large and bright near the bottom of the scene. Pandora (84 kilometers, or 52 miles across) sits outside the F ring, below center. Epimetheus (116 kilometers, or 72 miles across) is a speck on the far side of the ringplane, immediately to the right of Saturn's limb. Most of the other bright specks near the rings are background stars.

This view looks toward the unilluminated side of the rings from about 8 degrees above the ringplane. The image has been brightened to enhance the appearance of the small moons.

The image was taken with the Cassini spacecraft wide-angle camera on June 2, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 918 nanometers.
