High-Altitude Clouds

Golden hues continue to creep northward on Saturn, subduing the blues and grays the Cassini spacecraft witnessed upon arrival in mid-2004. This view was acquired from about 27 degrees above the ri...

Twirling vortices swim through a vast ocean of hydrogen and helium in Saturn's far north. This view looks toward a region at 70 degrees north latitude. The image was taken with the Cassini spacec...

This image, taken by NASA's Dawn spacecraft, shows a knobby surface on Ceres. The region is adjacent to the giant impact crater Urvara.

Janus and Tethys demonstrate the main difference between small moons and large ones.

The Cassini spacecraft sits on display for the media in the Payload Hazardous Servicing Facility at the Kennedy Space Center in August 1997. Cassini is a cooperative project of NASA, the Europea...

NASA's Dawn spacecraft obtained this image with its framing camera on August 6, 2011. Old and heavily cratered terrain is shown on Vesta. The framing camera has a resolution about 280 yards (260 me...

Dark Side of Dione July 19, 2004 Full-Res: PIA05418 The icy, cratered surface of Saturn's moon Dione shows more than just its sunl...

A portion of the rugged rim of Occator Crater is seen in this image from NASA's Dawn spacecraft. Occator, a young crater approximately 80 million years old.

Mariner 9's view of the "labyrinth" at the western end of Vallis Marineris on Mars. 

Cassini Aims High in Upcoming Titan Flyby Cassini's next close flyby of Titan will be on Saturday, Sept. 23. This will be one of Cassini's closest flybys yet of Titan, at just 960 kilometers (600 ...

As northern winter ends on Saturn and the Cassini spacecraft's view of the north pole improves, the swirls and eddies visible until now only in the south are gradually coming into view in the north...

This almost surreal view of Iapetus was acquired by Cassini about 10 minutes after the spacecraft's closest approach to the icy moon during a close flyby on New Year's Eve 2004. The image shows Ia...

The northern and southern hemispheres of Rhea are seen in these polar stereographic maps, mosaicked from the best-available Cassini and Voyager images. Six Voyager images fill in gaps in Cassini's...

This composite was produced from images returned yesterday, January 14, 2005, by the European Space Agency's Huygens probe during its successful descent to land on Titan. It shows the boundary betw...

Cassini's prying infrared vision allows details of Saturn's storm-ridden hydrogen atmosphere to be revealed as never before. North of the dark south polar region is what may be a "polygonal wave" ...

This image from NASA's Dawn spacecraft shows the hummocky (wavy/undulating) terrain of Vesta's Rheasilvia quadrangle, which is the south polar region.

Bright, high-altitude clouds interact with dark, deeper structures near Saturn's south pole. The dark vortices near lower right are two especially large examples of such deep structures. These vort...

Just as Saturn's famous hexagonal shaped jet stream encircles the planet's north pole, the rings encircle the planet, as seen from Cassini's position high above.

The center of Ezinu Crater on Ceres is seen in this view from NASA's Dawn spacecraft. The crater features a network of canyon-like features. Ezinu measures about 72 miles (116 kilometers) in diamet...

This image from NASA's Dawn spacecraft are located in asteroid Vesta's Floronia quadrangle, in Vesta's northern hemisphere. There are also many hummocky slumps of material around the crater's walls...

A star field in the constellation Cepheus is a composite of two 600-second exposures by the Framing Camera acquired during tests on December 3, 2007.

This area imaged by the Cassini radar system during the spacecraft's third close flyby of Titan on Feb. 15, 2005, is just to the east of the Circus Maximus impact feature (see http://photojournal.j...

The Cassini spacescraft takes a break from the Saturn system to check out the Seven Sisters. Cassini imaged the Pleiades star cluster, also called the Seven Sisters, as part of a routine to moni...

It may look as though Saturn's moon Mimas is crashing through the rings in this image taken by NASA's Cassini spacecraft, but Mimas is actually 28,000 miles (45,000 kilometers) away from the rings.

Titan's atmosphere makes Saturn's largest moon look like a fuzzy orange ball in this natural color view from the Cassini spacecraft. Titan's north polar hood is visible at the top of the image, an...
