Merging Saturnian Storms
Joining other moons in heralding the coming of Saturn's August 2009 equinox, the moon Tethys casts its shadow across Saturn's F ring and part of the A ring. The penumbra, or outer non-opaque part ...
Trumpeting the Equinox
Saturn sits nested in its rings of ice as Cassini once again plunges toward the graceful giant.
On the Final Frontier
The shadow of the moon Epimetheus crosses Saturn's rings in this image taken as the planet approached its August 2009 equinox. The moon Epimetheus (113 kilometers, or 70 miles across), a co-orbita...
This plot shows how daytime temperatures at low latitudes on the dark material on Saturn's moon Iapetus vary with time of day, from about 130 Kelvin (-226 Fahrenheit) at noon to about 70 Kelvin (-3...
Iapetus Temperature Variation Map
The Huygens probe descends through Titan's murky, brownish-orange atmosphere of nitrogen and carbon-based molecules, beaming its findings to the distant Cassini orbiter. The probe is equipped with...
Probe over Titan
When printed on letter sized paper this poster shows the size of the 'rocks' on Titan's surface in their true size. The left image was taken with the descent imager/spectral radiometer onboard the...
More tradition than superstition, “lucky peanuts” are a fixture at major deep space mission events since 1964.
Cassini "Lucky" Peanuts
Tethys floats before the massive, golden-hued globe of Saturn in this natural color view. The thin, dark line of the rings curves around the horizon at top. Visible on Tethys (1,071 kilometers, or...
Adrift at Saturn
Dark Desolation June 14, 2004 Full-Res: PIA06069 On June 11, 2004, during its closest approach to Phoebe, Cassini obtained this ex...
Held in gravity's embrace, Saturn's darkened, icy rings encircle the clouded gas giant. This view looks toward the unilluminated side of the rings from about 29 degrees above the ringplane. The ri...
In Saturn's Grasp
This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image, with a resolution of 450 feet (140 meters) per pixe...
Dawn HAMO Image 22
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
A group of bright spokes tightly cluster together in Saturn's B ring. The spokes seen here generally all exhibit the same degree of shearing, or tilting, but some deviations are apparent. In this i...
The Spoke Search
The Cassini spacecraft examines the icy, crater-saturated face of Rhea. This view looks toward the anti-Saturn side of Rhea (1,528 kilometers, or 949 miles across). North is up. The image was tak...
This image, taken by NASA's Dawn spacecraft, shows dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,400 feet (410 meters) per pixel, was take...
Dawn Survey Orbit Image 22
Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.

The Cassini spacecraft looks down on the cratered northern leading hemisphere of Dione, showing the moon's pockmarked surface. This view is centered on terrain at 42 degrees north latitude, 131 de...
Dione's Cratered Surface
These images, from Dawn's visible and infrared mapping spectrometer (VIR), highlight two regions on Ceres containing bright spots. The top images show a region scientists have labeled '1' while the...
Dawn VIR Images of Ceres
An extreme false-color view of Tethys reveals a surface detail not visible in a monochrome view taken at the same time. The false-color view shows a color transition from the moon's Saturn-facing ...
Transition on Tethys
Slipping into shadow, the south polar vortex at Saturn's moon Titan still stands out against the orange and blue haze layers that are characteristic of Titan's atmosphere.

This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 4, 2015, from a distance of 8,400 miles (13,600 kilometers).
Dawn RC3 Image 8
The shadow of the moon Enceladus appears on Saturn just south of the thin shadow of the planet's rings in this image captured shortly after Saturn's August 2009 equinox. Enceladus (504 kilometers,...
Shadow South of Another
Saturn's moon Mimas joins the planet's rings which appear truncated by the planet's shadow in this Cassini spacecraft image. Saturn is off to the left, out of view here. The inner rings are just v...
Craters cover the rugged surface of Saturn's moon Janus. The view is from 42 degrees above the moon's equator. North on Janus (179 kilometers, or 111 miles across) is towards the top of the image....
