Great Dark Spot

+ Version with labels Cassini shot past the surface of Saturn's moon Enceladus on Aug. 11, 2008, acquiring a set of seven high-resolution images targeting known jet source locations on the moo...

These mosaics of the south pole of Saturn's moon Titan, made from images taken almost one year apart, show changes in dark areas that may be lakes filled by seasonal rains of liquid hydrocarbons. ...

Three very different worlds crowd the frame in this unique view from the Cassini spacecraft, which although partly overexposed, provides a splendid look at several major targets of interest for the...

Just before Saturn's August 2009 equinox, Dione joined other Saturnian moons in casting shadows on the planet's main rings. Dione (1,123 kilometers, or 698 miles across) is not pictured, but that ...

A grandiose gesture of gravity, Saturn's icy rings fan out across many thousands of kilometers of space. The moon Pan (26 kilometers, or 16 miles across) dutifully follows its path, like the billio...

This image, taken by NASA's Dawn spacecraft on June 6, 2015, features a tall mountain on Ceres that is 4 miles (6 kilometers) high -- among the tallest features seen on Ceres to date.

The Cassini spacecraft studies the dynamics of Saturn's blustery cloud bands as spring approaches in the northern hemisphere. Janus casts its shadow onto Saturn at right, just above the curving s...

As Cassini approached the intriguing ice world of Enceladus for its extremely close flyby on July 14, 2005, the spacecraft obtained images in several wavelengths that were used to create this false...

This near-true color view from Cassini reveals the colorful and intriguing surface of Saturn's moon Iapetus in unrivaled clarity

Comet C/2020 F3 (NEOWISE) over Deer Valley, Utah.

This image of complex bright and dark material relationships in Occator Crater on Ceres was obtained by NASA's Dawn spacecraft on July 3, 2018 from an altitude of about 30 miles (48 kilometers).

NASA's Dawn spacecraft took this image on Feb. 4, 2016, showing a double impact feature at high northern latitudes on Ceres, just south of the large crater named Ghanan.

This image from NASA's Dawn spacecraft shows a part of Vesta's northern hemisphere, which is mostly in darkness. Since Dawn's arrival at asteroid Vesta the sun has not illuminated Vesta's most nort...

Bright spokes and the shadow of a moon grace Saturn's B ring in this Cassini spacecraft image. Spokes are radial markings scientists continue to study, and they can be seen here stretching from th...

The Cassini spacecraft looks down under at the tortured south polar region of Enceladus, crossed by its "tiger stripes," or sulci, as the long, nearly parallel fractures are officially known. The u...

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...

This montage of images, made from data obtained by Cassini's visual and infrared mapping spectrometer, shows the location on Saturn where the NASA spacecraft entered Saturn's atmosphere on Sept. 15...

+ View Original Image   High-resolution Cassini images show an astonishing level of structure in Saturn's Cassini Division, including two ringlets that were not seen in NASA Voyager spacecraft im...

This is a portion of a Cassini radar mapper image obtained by the Cassini spacecraft on its Dec. 21, 2008, flyby of Saturn's moon Titan. The area shown covers the southern boundary of an equatori...

Cassini Project Scientist Linda Spilker explains the tradition of lucky peanuts at a gathering for mission team members, family and friends in Von Karman Auditorium at NASA’s Jet Propulsion Laborat...

This set of images exposes details on small and crumpled-looking Helene. Large portions of this Trojan moon of Dione appear to have been blasted away by impacts. Cassini passed within 50,000 kilom...

A string of three of Saturn's icy moons encircles the planet in this Cassini image. Visible here are: Mimas (397 kilometers, or 247 miles across) near lower right; Janus (181 kilometers, or 113 mi...

These natural color views (and corresponding animated movie sequences) from NASA's Cassini spacecraft compare the appearance of Saturn’s north-polar region in June 2013 and April 2017. 

NASA's Curiosity Mars rover used a new drill method to produce a hole on February 26 in a target named Lake Orcadie. The hole marks the first operation of the rover's drill since a motor problem be...

This is a computer simulation of the final stage of the growth of a "clump" in Saturn's rings. The gravity from a hypothesized moonlet (solid gray sphere in frame center) has collected smaller ring...
