Great Dark Spot
This stereo image, or anaglyph, shows huge mountains on Saturn's moon Iapetus, imaged by NASA's Cassini spacecraft during its very close flyby in Sept. 2007. These mountains are located at the moon...
Towering Peaks of Iapetus
This moody true color portrait of Saturn shows a world that can, at times, seem as serene and peaceful as it is frigid and hostile. Saturn's unlit-side rings embrace the planet while their shadows ...
Shadow and Shade
NASA's Cassini spacecraft obtained this unprocessed image of Saturn's moon Helene on June 18, 2011. This image has not been validated or calibrated. A validated/calibrated image will be archived w...
Another View of Helene
This movie, showing six of Saturn's small ring-region moons as they raced around the planet, was made from images taken by the Cassini spacecraft on Nov. 15, 2004. The moons appear in following or...
Race of the Moons
Voyager 2 obtained this high-resolution picture of Saturn's rings on August 22, 1981 when the spacecraft was 4 million kilometers (2.5 million miles) away. Evident here are the numerous "spoke" fea...
This high-resolution image from Cassini shows a region of "smooth plains" terrain on the surface of Saturn's moon Enceladus, located slightly north of the equator on the moon's Saturn-facing hemisp...
Seeing Enceladus' Faults
This view from NASA's Dawn spacecraft shows the Cerean terrain. The crater in the upper left corner displays smooth, relatively crater-free walls and small spurs of compacted material.

A new image of Titan taken by Cassini provides a closer, clearer view of an interesting bright feature surrounded by darker material. During the two most recent flybys of Titan, on March 31 and A...
Angular Bright Spot
The Cassini spacecraft provides a window on the awesome scale of the Saturn system, with the giant planet dominating one of its smaller satellites. Orbiting here, just outside the main ring system...
Pebble in a Pond
This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 5 and 6, 2015, from a distance of 8,400 miles (13,600 kilometers).

This poster shows a composite view from the descent imager/spectral radiometer taken while the European Space Agency's Huygens probe was setting on Titan's surface, juxtaposed with a similarly scal...
A crescent of Tethys displays two of the moon's large craters. Penelope Crater can be seen at the top left. Antinous Crater is in the bottom left, in the far southern latitudes. Features on Tethys...
Hubert Curien was born on 30 October 1924 in the Vosges region of eastern France. While a student, he enlisted in the French resistance and was commended for bravery in action. He entered the Ecole...
The north pole of Saturn sits at the center of its own domain. Around it swirl the clouds, driven by the fast winds of Saturn. Beyond that orbits Saturn's retinue of moons and the countless small p...
At the Center
This view from NASA's Dawn spacecraft features the rugged rim of Occator Crater at left. A number of thin fractures are visible, roughly parallel to the rim.

Like a rope of brilliant neon, Saturn's rings outshine everything else in this night side view, while the sunlit southern face of the rings reflects a dim glow onto the atmosphere below. When viewe...
This low resolution view of Tethys provides scientists with useful information about the moon's surface properties, regardless of the image's small size. The view, which was taken using an ultrav...
Newly assembled radar images from the Cassini spacecraft provide the best view of the hydrocarbon lakes and seas on the north pole of Saturn's moon Titan, while a new radar image reveals that Titan...
Cassini Reveals Titan's North and South Poles
This image of bright material in Occator Crater on Ceres was obtained by NASA's Dawn spacecraft on July 5, 2018 from an altitude of about 34 miles (55 kilometers).
Bright Material in Occator Crater
These images were obtained by the Dawn spacecraft on July 23, 2011. The bottom two images are false-color, where different colors represent visible and infrared light wavelengths.

NASA is Born
This artist's impression shows the 'light curve' produced by a star passing behind Titan, Saturn's biggest moon. When such occultation events take place, the light from the star is blocked out. B...
Light Curve During Titan Occultation Event
Cassini made a close flyby of Saturn's moon Iapetus on Sept. 10, 2007, and the visual and infrared mapping spectrometer obtained these images during that event. These two images show a higher reso...
Iapetus' Equatorial Region
The Cassini spacecraft and Huygens probe begin their seven-year journey to the ringed planet. The successful launch of Cassini aboard a Titan IVB/Centaur occured at 4:43 a.m. EDT, October 15, 1997....
