Speeding Away from Tethys
Saturn's moon Dione hangs in front of Saturn's rings in this view taken by NASA's Cassini spacecraft during the inbound leg of its last close flyby of the icy moon.
Dione: Craters and Rings
Two pairs of moons make a rare joint appearance. The F ring's shepherd moons, Prometheus and Pandora, appear just inside and outside of the F ring (the thin faint ring furthest from Saturn).
This remarkably clear view from that flyby shows the moon's characteristically dark mid-latitudes, and more southern terrain than the Cassini spacecraft has usually been able to glimpse. This was ...
This Cassini image shows predominantly the impact-scarred leading hemisphere of Saturn's icy moon Rhea (1,528 kilometers, or 949 miles across). The image was taken in visible light with the Cassin...

This infrared image from Juno gives an unprecedented view of the southern aurora of Jupiter.

Zadeni Crater on Ceres is featured in this image from NASA's Dawn spacecraft. This large southern-hemisphere crater is 79.5 miles (128 kilometers) in diameter and is named for an ancient Georgian g...
Dawn XMO2 Image 9
Possible variations in chemical composition from one part of Saturn's ring system to another are visible in this Voyager 2 image as color variations that can be enhanced with special computer-proce...
The small ring moon Atlas is seen here, on the far side of Saturn's immense ring system. Cassini was only 0.6 degrees above the ring plane when this image was taken. Atlas is 32 kilometers (20 ...
Straight Across the Rings
Hyperion, the eighth largest of Saturn's nearly 60 known moons, is covered in craters and landslides. Sprinkled over the icy surface is a thin layer of organic dust, which has somehow been concentr...
Organics Sprinkled on Hyperion
This false-color image obtained by NASA's Dawn spacecraft shows a crater on the giant asteroid Vesta. The reddish coloring below the crater points to material that was hurled from Vesta's interior ...
False-Color Image Shows Proof of an Impact
Spiral density waves in Saturn's A ring reveal the gravitational signatures of distant moons as they subtly tug on the countless particles orbiting in the ring plane. Resulting from a process call...
Saturn's Watch Spiral
Nearly invisible upon first glance, Saturn's moon Enceladus is a small bright dot beyond the planet's rings in this Cassini spacecraft image. Enceladus (504 kilometers, or 313 miles across) is vis...
Speck of Enceladus
The F ring shepherd Pandora is captured here along with other well-known examples of how Saturn’s moons shape the rings.
Shepherd and Flock
In this fabulous close-up, Cassini peers directly through regions of the A, B and C rings (from top to bottom here) to glimpse shadows of the very same rings cast upon the planet's atmosphere. Near...
Looking Through the Rings
This composite infrared image, derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission to Jupiter during a Feb. 2, 2017, pass over the planet...
Cyclones Encircle Jupiter's North Pole
This set of images from NASA's Cassini mission shows how the gravitational pull of Saturn affects the amount of spray coming from jets at the active moon Enceladus. Enceladus has the most spray whe...

+ View Full-Res This image was obtained by Cassini's radar instrument during a flyby on April 30, 2006. The radar antenna was pointing toward Titan at an altitude of 1,855 kilometers 1,153 miles) ...

When Galileo first observed Venus displaying a crescent phase, he excitedly wrote to Kepler (in anagram) of Venus mimicking the moon-goddess. He would have been delirious with joy to see Saturn and...
Mimicking the Moon
Vortices mingle amidst other turbulent motions in Saturn's atmosphere in these two comparison images. The image on the right was taken about two Saturn rotations after the image on the left. Both ...
The Cassini spacecraft captures three moons at once as they hurtle around Saturn. In the background, Saturn's night side covers the more distant portion of the rings, betraying the presence of the ...
Deputy Administrator Shana Dale unveiled the agency's anniversary logo Thursday in a ceremony at WIRED Magazine's annual NextFest in Los Angeles. NASA's "birthday" is October 1, 1958.
NASA Unveils 50th Anniversary Logo
The Cassini spacecraft looks down on the north pole of Titan, showing night and day in the northern hemisphere of Saturn's largest moon. This view is centered on terrain at 49 degrees north latitu...
