Fine, sharp-edged details and smooth gradients in the ring features of the Cassini Division are imaged here together at excellent resolution. The faint ringlet in the dark gap left of center is a ...

Mimas drifts along in its orbit against the azure backdrop of Saturn's northern latitudes in this true color view. The long, dark lines on the atmosphere are shadows cast by the planet's rings. Sa...

Hydrogen is most abundant in areas with low reflectivity, or albedo, on the giant asteroid Vesta, as shown in this contour map from NASA's Dawn mission.

The longest-lived continuously monitored electrical storm ever observed on Saturn continues to churn through the tempest-tossed region nicknamed "Storm Alley" because of its preponderance of storm ...

Titan's First Close-Up October 26, 2004 This image is one of the closest ever taken of Saturn's hazy moon Titan. It was captured by Cassini's imaging scien...

This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013.

The sounds and spectrograms in these two videos represent data collected by the Radio and Plasma Wave Science, or RPWS, instrument on NASA's Cassini spacecraft, as it crossed the plane of Saturn's ...

The strands of Saturn's F ring disappear into the darkness of the planet's shadow. Background stars make trails across the sky during the long exposure. This view looks toward the unlit side of th...

Cassini finds artistic harmony in the dark and icy realm of Saturn. The view shows the crescent of Tethys (1,071 kilometers, or 665 miles across) and the outer edge of Saturn's main rings. The dim...

This Cassini view of Saturn's moon Tethys shows several large craters near the moon's eastern limb. These craters have fanciful names such as Phemius, Polyphemus and Ajax. The moon's massive rift-l...

A thin sliver of Mimas is illuminated, the long shadows showing off its many craters, indicators of the moon's violent history.

Mars' largest moon Phobos as seen by Mars Reconnaissance Orbiter in 2008.

This false-color mosaic from NASA's Cassini spacecraft shows the tail of Saturn's huge northern storm. See Chronicling Saturn’s Northern Storm to learn more about this storm and watch its develop...

Martian weather between May 14, 2018 and May 20, 2018: The Mars Color Imager (MARCI) aboard the Mars Reconnaissance Orbiter (MRO) acquires a global view of the red planet and its weather patterns e...

This view of Ceres from NASA's Dawn spacecraft, taken on May 29, 2016, features a small crater at upper left that adjoins Messor Crater.

This image from NASA's Dawn spacecraft, taken on June 6, 2016, shows an area of Ceres that includes a small, bright crater.

Saturn's north polar hexagon appears to be a long-lived feature of the atmosphere, having been spotted in images of Saturn in the early 1980s, again in the 1990s, and then by the Cassini spacecraft...

This artist's concept shows NASA's Dawn spacecraft arriving at the dwarf planet Ceres. Dawn travels through space using a technology called ion propulsion, with ions glowing with blue light are acc...

Compared to the gas giant, the two moons shown on either side of Saturn seem particularly small in this Cassini spacecraft view. Tethys (660 miles, or 1,062 kilometers across) is on the right of t...

Although we are used to seeing Saturn’s moons lit directly by the Sun, sometimes we can catch them illuminated by "Saturnshine."

This simulated view from NASA's Cassini spacecraft shows the expected positions of Saturn and Earth on July 19, 2013, around the time Cassini will take Earth's picture. Cassini will be about 898 mi...

It's difficult to get a sense of scale when viewing Saturn's rings, but the Cassini Division (seen here between the bright B ring and dimmer A ring) is almost as wide as the planet Mercury.

Two moons on opposite sides of the rings slide past each other in this stately portrait of Saturn. Dione (1,126 kilometers, or 700 miles across), on the far side of Saturn, appears above the rings...

Part of the shadow of Saturn's moon Epimetheus appears as if it has been woven through the planet's rings in this Cassini image taken about a month and a half before the planet's August 2009 equino...

Saturn's moon Janus casts a shadow on the F and A rings while the moon Prometheus, seen on the left of the image, creates a streamer-channel in the thin F ring. The gravity of potato-shaped Promet...
