Final Assembly at the Cape
The Cassini spacecraft spies two types of waves in Saturn's A ring: a spiral density wave on the left of the image and a more pronounced spiral bending wave near the middle. See Two Kinds of Wave ...
This frame from an animated sequence of images shows northern terrain on the sunlit side of dwarf planet Ceres as seen by NASA's Dawn spacecraft on April 14 and 15, 2015.
Settling in at Ceres
The Cassini spacecraft looks toward Saturn's largest moon, Titan, and spies the huge Kraken Mare in the moon's north. Kraken Mare, a large sea of liquid hydrocarbons, is visible as a dark area nea...
Titan's Kraken Mare
The Cassini spacecraft examines the anti-Saturnian side of Dione and shows the cratered surface east of the moon's distinctive wispy terrain.
East of Wisps
This artist's illustration shows the likely interior structure of Saturn's moon Titan deduced from gravity field data collected by NASA's Cassini spacecraft. The investigation by Cassini's radio sc...
Titan's cool and sluggish interior
This image high-resolution image of Juling Crater on Ceres, taken by NASA's Dawn spacecraft, reveals, in exquisite detail, features on the rims and crater floor.
Rhea's crater-saturated surface shows a large bright blotch, which was likely created when a geologically recent impact sprayed bright, fresh ice ejecta over the moon's surface. The rim of the gre...
Bright Ice Below
This image of asteroid Vesta from NASA's Dawn spacecraft shows a relatively smooth area of Vesta's surface. This region is smooth because it is mostly covered by fine-grained debris, known as regol...
Surface Covered by Regolith and Fresh Young Impacts
Saturn's largest moon, Titan, looks small here, pictured to the right of the gas giant in this Cassini spacecraft view. Titan (3,200 miles, or 5,150 kilometers across) is in the upper right. Satur...
Beside a Giant
This is Cassini's best look yet at the Trojan moon Telesto (24 kilometers, or 15 miles across), which orbits Saturn about 60 degrees ahead of the much larger Tethys (1,071 kilometers, or 665 miles ...
Enceladus appears as a rather bland orb in this far-off snapshot, but the dark markings near its south pole belie that assumption. The markings, called sulci, are long, roughly parallel fractures f...
This image is a portion of the swath acquired by the Cassini Titan radar mapper on Feb. 15, 2005, on the mission's second opportunity to image the surface with radar. The frame, measuring about ...
This unusual view of Saturn's moon Hyperion (266 kilometers, or 165 miles across) shows just how strangely shaped this tumbling little moon is. Hyperion is the largest of Saturn's irregularly shape...
This Cassini radar image shows two lakes "kissing" each other on the surface of Saturn's moon Titan. The image from a flyby on Sept. 23, 2006, covers an area about 60 kilometers (37 miles) wide ...
Titan's 'Kissing Lakes'
NASA's Dawn spacecraft shows the central area of the south polar basin. This view is rotated by approximately 60°.
Topography of Vesta's South Polar Region III
+ View Full Res These images were obtained by Cassini's radar instrument during a flyby on Oct. 2, 2007. The radar antenna was pointing toward Titan at an altitude of 975 kilometers (605 miles) du...
Titan Radar Swath (T-36 Flyby - Oct. 2, 2007)
From Los Angeles (and western states) find the moon, Saturn and Venus in the western-southwestern sky after sunset on July 19th. Saturn appears as a golden “star” brighter than any of the surroundi...
July 19, 2013: How to Find Saturn (Los Angeles)
Wave-like patterns in Saturn's rings and a nearly half-full Mimas are caught together in this image from Cassini. Mimas is 398 kilometers (247 miles) across. The image was taken in visible light w...
Saturn's Ring Patterns
Terrestrial planets (shown in the top row) are compared with the Solar System's largest satellites. Titan is the second-largest satellite in the solar system. Only Jupiter's satellite Ganymede is l...
Titan's Relative Size
Cassini's radar instrument finds lakes in the southern hemisphere of Titan during the most recent Titan flyby. This is the first confirmation of lakes in the southern hemisphere with the radar ins...
Radar Sees Lakes in Titan's Southern Hemisphere
A color portrait of Saturn's sunlight-scattering rings hosts a group of several moons. Enceladus (505 kilometers, or 314 miles across) is visible at top. At bottom, in increasing distance from the...
Field of Moons
This image from NASA's Dawn spacecraft shows cratered terrain in the northern hemisphere of Ceres. Ikapati crater (top) appears with several flat plains filled by flows, smooth material and ejecta ...
Dawn HAMO Image 64
Saturn's fourth-largest moon, Dione, can be seen through the haze of the planet's largest moon, Titan, in this view of the two posing before the planet and its rings from NASA's Cassini spacecraft.
Titan and Dione
Tiny Epimetheus is dwarfed by adjacent slivers of the A and F rings. But is it really? Looks can be deceiving!
During its Sept. 7, 2005, flyby of Titan, Cassini acquired images of territory on the moon's Saturn-facing hemisphere that were assembled to create this mosaic. Once known only as "the H" because ...
