Cassini Enters Saturn's Orbit
Although Saturn's moon Pan is absent from this image of the A ring's Encke Gap, the moon's handiwork is still displayed. The two ringlets seen in the gap are maintained by the gravitational action...
The northern and southern hemispheres of Dione are seen in these polar stereographic maps, mosaicked from the best-available clear-filter images from NASA's Cassini mission. Each map is centered o...
Map of Dione - December 2011
This picture of Venus was taken by the Galileo spacecrafts Solid State Imaging System on February 14, 1990, at a range of almost 1.7 million miles from the planet.
Venus Cloud Patterns
The three mosaics shown here were composed with data from Cassini's visual and infrared mapping spectrometer taken during the last three Titan flybys, on Oct. 28, 2005 (left image), Dec. 26, 2005 (...
Mapping Titan's Changes
Saturn's small moon Prometheus, slightly overexposed in this image, shows off its potato-like shape as it orbits in the Roche Division between the A ring and thin F ring. Prometheus (86 kilometers...
Little Tuber Moon
On Oct. 24, 2016, NASA's Dawn spacecraft captured the low angle of illumination bringing this pair of nested craters near Ceres' south pole into sharp relief.
Dawn XMO2 Image 31
N00041287.jpg was taken on October 11, 2005 and received on Earth October 12, 2005. The camera was pointing toward TELESTO at approximately 14,630 kilometers away, and the image was taken using the...
Best Image Yet of Telesto
The profile of the 450-kilometer-wide (280-mile) crater Odysseus makes this image look as if someone sliced off a chunk of Tethys (1,071 kilometers, or 665 miles across). According to measurements ...
Profile of Odysseus
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
The Cassini spacecraft watches Saturn's small moon Epimetheus orbiting beyond the planet's rings. See Epimetheus Revealed and Epimetheus: Up-Close and Colorful for closer views of this moon. Epime...
Epimetheus Beyond Rings
Alternating light and dark bands, extending a great distance across Saturn's D and C rings, are shown here in these Cassini images taken one month before the planet's August 2009 equinox. The C ri...
Extensive Spiral Corrugations
A section of Saturn's perturbed F ring displays kinks in its bright strands. At left, edge waves in the Encke Gap, caused by the presence of Pan, can be seen, along with two faint ringlets. This v...
Following a successful close flyby of Enceladus, NASA's Cassini spacecraft captured this artful composition of the icy moon with Saturn's rings beyond.
Titan in Natural Color Full-Res: PIA06081 Despite the views of the surface of Saturn's Titan moon provided by the Cassini spacecraft...
Titan in Natural Color
Sunlight scatters through Titan's atmosphere, illuminating high hazes and bathing the entire moon in a soft glow. This high phase angle view of Titan was acquired from 21 degrees below the smoggy ...
This view is part of a montage of images from the NASA Cassini and Voyager missions shown in D Ring Revelations. The inset image from the montage is presented here by itself and in its original ori...
D Ring Revelations (Inset image)
Cassini turns its gaze toward Saturn's outer A ring to find the moon Pan coasting behind one of the thin ringlets which it shares with the Encke Gap. Pan is 26 kilometers (16 miles) across. Unders...
Ring Study Subjects
This image of Ceres from NASA's Dawn spacecraft was taken at an oblique viewing angle relative to the surface. The crater to the upper right is named Juling which displays prominent spurs of compac...
Dawn LAMO Image 32
The Cassini spacecraft looks down, almost directly at the north pole of Dione. The feature just left of the terminator at bottom is Janiculum Dorsa, a long, roughly north-south trending ridge. Lit...
Dione: North Polar View
Plumes of water vapor and other gases escape at high velocity from the surface of Saturn's moon Enceladus, as shown in this artist concept. The "shear heating" mechanism suggests that tidal forces...
Shear Heating on Enceladus
Canyons and mountain peaks snake along the terminator on the crater-covered, icy moon Dione. With the Sun at a low angle on their local horizon, the line of mountain ridges above center casts shado...
Shadows on Ice
Saturn's D ring is easy to overlook since it's trapped between the brighter C ring and the planet itself.
Dusty D Ring
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).
Dawn RC3 Image 19
This image NASA's Dawn spacecraft shows is located in Vesta's Rheasilvia quadrangle, near Vesta's south pole. Severina crater has a fresh, sharp rim and a smaller, presumably younger, crater on its...
