Arrival at Saturn

Saturn and Dione regard Enceladus -- the object their gravitational tug-of-war. Dione (1,126 kilometers, or 700 miles across) is seen next to Saturn here. Enceladus (505 kilometers, or 314 miles ac...

The rim of the crater blocks sunlight coming from the right, creating a moody scene on Ceres. NASA's Dawn spacecraft took this image on June 16, 2016.

                  Intricate C Ring Details December 7, 2004   Full-Res: PIA06537   Saturn's inner C ring spreads across th...

Epimetheus (116 kilometers, or 72 miles across, at right) and Janus (181 kilometers, or 113 miles across, at left) are lit here by reflected "greylight" from Saturn. The Sun brightens only thin sli...

Cassini took this image of Enceladus on Dec. 23, 201 from approximately 303,344 miles (488,185 kilometers) away. This image has not been validated or calibrated. A validated/calibrated image will ...

The surface of Saturn's moon Dione is rendered in crisp detail against a hazy, ghostly Titan. A portion of the ''wispy'' terrain of Dione's trailing hemisphere can be seen on the right (see Wispy ...

Saturn's ring-embedded moons, Pan and Daphnis, are captured in a single Cassini spacecraft narrow-angle frame in an alignment they repeat with the regularity of a precise cosmic clock. Pan is close...

This Cassini image shows an assortment of vortices and wavy interfaces where air masses moving at different speeds intersect. Bright, narrow and linear cloud features of the north appear to be movi...

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 was taken on September 20, 2015, and has a resolutio...

The view from NASA's Dawn spacecraft shows an unnamed crater that lies in the northeast part of the larger impact feature Gaue. The area is dominated by small craters and is relatively smooth in ge...

The Cassini spacecraft captures Janus in the foreground, with Dione in the distance beyond. The image was taken two hours after Hiding Dione, in which Cassini imaged Dione beyond the rings. Janus...

Cassini prepared for its rendezvous with Dione on Oct. 11, 2005, capturing the brilliant, cratered iceball in front of its shadow-draped planet. The terrain seen here becomes notably darker toward...

This view of Tethys displays three of the moon's most notable surface features. At upper left is the giant Odysseus impact basin. At lower right is the great scar of Ithaca Chasma. Extending from e...

The most detailed images of Ultima Thule — obtained just minutes before the spacecraft's closest approach at 12:33 a.m. EST on Jan. 1, 2019 — have a resolution of about 110 feet (33 meters) per pix...

Ever-changing kinks and wiggles define Saturn's dynamic F ring. The evolution of F-ring features like those seen here are of interest to ring scientists because they reveal a great deal about the p...

This artist's rendition shows the Huygens probe as it reaches the surface of Titan. The Cassini spacecraft (top left corner of the image) flies over with its High Gain Antenna pointed at the probe....

This graphic illustrates the interior of Saturn's moon Enceladus. It shows warm, low-density material rising to the surface from within, in its icy shell (yellow) and/or its rocky core (red). A NA...

Astronaut Edwin E. Aldrin Jr., lunar module pilot, walks on the surface of the moon near a leg of the Lunar Module during the Apollo 11 extravehicular activity (EVA).

N00164313.jpg was taken on October 16, 2010 and received on Earth October 17, 2010. The camera was pointing toward PALLENE, and the image was taken using the RED and CL2 filters. This image has no...

On May 12, 2007, Cassini completed its 31st flyby of Saturn's moon Titan, which the team calls T30. The radar instrument obtained this image showing the coastline and numerous island groups of a p...

Evoking the haunting beauty of Earth's Moon, a crescent Enceladus appears in the skies around Saturn. Lit terrain seen here is on the Saturn-facing hemisphere of Enceladus. North on Enceladus is u...

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 ...

This composite image shows an infrared view of Saturn's moon Titan from NASA's Cassini spacecraft, acquired during the mission's ''T-114'' flyby on Nov. 13, 2015.
