Jupiter Magnetosphere

Viewed nearly edge-on, Saturn's rings appear dark and pencil-thin against the backdrop of the planet's swirling clouds. Notable here are the shadows cast by the rings onto the northern hemisphere,...

Closing in on Titan July 3, 2004 Full-Res: PIA06111 Titan's veil begins to lift as Cassini's cameras peer through the hazy moon. ...

Saturn's moon Epimetheus is seen here from just beneath the ring plane, along with Saturn's intriguing F ring. The bright, knotted core of the F ring is flanked on both sides by thin, dusty strands...

A large crater can be seen in the southern hemisphere of Saturn's two-tone moon Iapetus. Lit terrain seen here is on the trailing hemisphere of Iapetus (914 miles, or 1,471 kilometers across), a ...

Almost all of the hydrocarbon seas and lakes on the surface of Saturn's moon Titan cluster around the north pole, as can be seen in this mosaic from NASA's Cassini mission.

This Solar & Heliospheric Observatory (SOHO) image, taken Sept. 18, 2009, shows a view of Saturn as it passes behind the sun, Cassini spacecraft in tow. Saturn Superior Conjunction is underwa...

Dickinson crater on Venus as seen by the Magellan orbiter radar.

Orbiting in the Encke Gap of Saturn's A ring, the moon Pan casts a shadow on the ring in this image taken about six months after the planet's August 2009 equinox. Pan (28 kilometers, or 17 miles a...

A Cassini spacecraft image captures a bright, oblong storm swirling high through the middle latitudes of the southern hemisphere. The image was taken through a spectral filter centered on waveleng...

On July 19, 2013, in an event celebrated the world over, NASA's Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings -- and, in the ba...

This mosaic of Titan's surface was made from 16 images. The individual images have been specially processed to remove effects of Titan's hazy atmosphere and to improve visibility of the surface nea...

Saturn's moon Epimetheus passes in front of Janus in this "mutual event" chronicled by the Cassini spacecraft. These three images were each taken a little more than a minute apart. These images ar...

This map of Saturn's moon Titan identifies the locations of mountains that have been named by the International Astronomical Union.

This image of asteroid Vesta is one of many images taken by NASA's Dawn spacecraft to create an animation showing the diversity of minerals through color representation.

This dramatic image shows Saturn's craggy moon Pandora skimming along the F ring's outer edge. Pandora orbits about 1,000 kilometers (620 miles) exterior to the ring, but in this view is projecte...

This image of Titan, taken by a Voyager spacecraft, shows Titan to be completely shrouded by a thick atmosphere. The atmosphere is about 95% nitrogen, the remainder methane as well as other hydroca...

NASA's Cassini spacecraft successfully completed its Oct. 1 flyby of Saturn's moon Enceladus, capturing these raw, unprocessed images of the moon and its dramatic plumes of water vapor and ice. Th...

The sun emitted a mid-level solar flare, peaking at 8:13 p.m. EDT on Oct. 1, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. 

This image from NASA's Dawn spacecraft shows craters with both sharp and smooth rims. The most obvious is the large crater in the bottom left of the image.

Four images from NASA's New Horizons' Long Range Reconnaissance Imager (LORRI) were combined with color data from the Ralph instrument to create this global view of Pluto.

These two images of Saturn show the entire south polar region, not just the little area around the core of the hurricane-like vortex.

The sunlit face of Saturn's rings shows magnificent detail in this image taken in near infrared light. Most notable is the transition in brightness toward the outer edges of the image, due to diffe...

Pandora is seen here, in isolation beside Saturn's kinked and constantly changing F ring.

Saturn's D ring--the innermost of the planet's rings--sports an intriguing structure that appears to be a wavy, or "vertically corrugated," spiral. This continuously changing ring structure provide...

This Cassini image shows the cratered surface of Saturn's moon Rhea, with impact craters near the terminator thrown into sharp relief. Rhea is Saturn's second-largest moon, at 1,528 kilometers (9...
