As Titan Turns

An illuminated quarter of the moon Tethys is imaged near a swath of Saturn's rings. Though the moon appears to be hanging directly below the rings, Tethys is actually farther from the Cassini spac...

Smooth terrain around the western rim of Ikapati Crater on Ceres is visible in this image from NASA's Dawn spacecraft. The area contains material ejected from Ikapati during its formation.

These two images of Saturn show the entire south polar region, not just the little area around the core of the hurricane-like vortex. Earth-like storm patterns seem to be powering this vortex. The...

Squinting at this view of Saturn's rings reveals not one but two of the four narrow ringlets in the Encke Gap (325 kilometers, or 200 miles, wide). The innermost of the two ringlets is much brighte...

This map illustrates the planned imaging coverage for the Descent Imager/Spectral Radiometer, onboard the European Space Agency's Huygens probe during the probe's descent toward Titan's surface on ...

Possible variations in chemical composition from one part of Saturn's ring system to another are visible in this Voyager 2 image as color variations that can be enhanced with special computer-proce...

One moment in an ancient, orbital dance is caught in this color picture taken by NASA's Cassini spacecraft on Dec. 7, 2000, just as two of Jupiter's four major moons, Europa and Callisto, were ne...

The Cassini spacecraft provides a stunning view of the Odysseus impact basin on Tethys. The enormous basin is 450 kilometers (280 miles) wide. The medium-sized crater Melanthius is seen along the ...

Cassini continues to survey the small worlds that orbit near Saturn's rings, capturing this view of Epimetheus.

This rock encountered by NASA's Curiosity Mars rover is an iron meteorite called "Lebanon."

Both of Saturn's F-ring shepherd moons are seen in this Cassini spacecraft view, which also features narrow ringlets in the Encke gap at left. Prometheus (102 kilometers, or 63 miles across) is ca...

The F ring shepherd moon Prometheus touches the face of Saturn once more before moving off into blackness and continuing in its orbit.

Odysseus Crater, with a size of epic proportions, stretches across a large northern expanse on Saturn's moon Tethys.

The Cassini spacecraft monitors the myriad cloud forms that drift in Saturn's atmosphere, helping scientists gain a better understanding of how energy is transported around, and from within, the pl...

Saturn's F ring shows several "mini-jets" near the upper-right of this image captured by the Cassini spacecraft. The A ring also appears in the lower-left of the image. The mini-jets are thought b...

This Cassini spacecraft view, taken from a vantage point 64 degrees above Dione's equator, looks down onto the bright fractures that cover the moon's trailing side. The fractures crisscross a regio...

On July 29, 2011, Cassini captured five of Saturn’s moons in a single frame with its narrow-angle camera. 

This enhanced image, taken by the framing camera instrument aboard NASA's Dawn spacecraft on July 9, 2011, views the south polar region of this giant asteroid.

The shepherd moon, Pandora, is seen here alongside the narrow F ring that it helps maintain. Pandora is 84 kilometers (52 miles) across. Cassini obtained this view from about four degrees above th...

Recent images of features in Saturn's C ring called "plateaus" reveal a streaky texture that is very different from the textures of the regions around them. 

NASA's Dawn spacecraft took images of Haulani Crater at a distance of 240 miles (385 kilometers) from the surface of Ceres.

Scientists have used data from the Cassini radar mapper to map the global wind pattern on Saturn's moon Titan using data collected over a four-year period, as depicted in this image. The arrows ...

The "flying saucer" in this image is the small moon Atlas (20 kilometers, 12 miles across), whose shadowy profile reveals its flattened shape. This image looks down onto the outer A ring, and throu...

This image is a mosaic of Vesta's equatorial region, composed of observations taken through the panchromatic filter on the framing camera onboard NASA's Dawn spacecraft on July 24, 2011.
