This natural color image of the limb of Triton was taken early in the morning of Aug. 25 1989, when the Voyager 2 spacecraft was at a distance of about 210,000 kilometers (128,000 miles) from the i...
The Limb of Triton
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 ...

The broad morphology of asteroid Vesta's mountain/central complex is clear in this image from NASA's Dawn spacecraft; it is a roughly circular topographic mound, which is approximately 200km in dia...

The moon Enceladus seems to hover above the outer reaches of Saturn's B ring. Below and to the right of Enceladus, four faint bands lie in the center of the dark Cassini Division. Recently, scient...

This image of Oppia AV-L-22, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.
This montage of views from NASA's Cassini spacecraft shows three of Saturn's small ring moons: Atlas, Daphnis and Pan at the same scale for ease of comparison.
A large sunspot was the source of a powerful solar flare and a coronal mass ejection (Sept. 6, 2017). The flare was the largest solar flare of the last decade. For one thing, it created a strong sh...

This map of the surface of Saturn's moon Enceladus illustrates the regions that will be imaged by the Cassini spacecraft's second very close flyby on March 9, 2005. At closest approach, the spacecr...
Cassini's Closest Enceladus Flyby
Looking closely at Saturn's moon Rhea during a somewhat distant flyby, Cassini provides this view of what appears to be a bright, rayed and therefore relatively young crater. This crater was also o...

During a flyby of Saturn's moon Enceladus on Oct. 1, 2011, the Cassini spacecraft snapped this portrait of the moon joined by its sibling Epimetheus and the planet's rings.
Hiding Little Brother
Bright strands in Saturn's ever changing F ring emerge from the planet's shadow. Several background stars are visible by the trails they created while the image was being exposed. This view looks...

A close-up view of the Keeler Gap, which is near the outer edge of Saturn's main rings, shows in great detail just how much the moon Daphnis affects the edges of the gap.
With no solid land to obstruct their progress, dark vortices often roll through Saturn's atmosphere for months or years, before merging with other vortices. On Earth, the continents usually halt th...
Beyond the ansa of Saturn's rings, a crescent Rhea completes this ring-and-moon composition. Rhea (1,528 kilometers, or 949 miles across) is near the middle of the bottom of the image. This view l...

“On July 19, 2013, you waved at Saturn. The Cassini spacecraft was there to snap a photo of not only us, but the Saturn system. Here’s Cassini’s view of Enceladus within Saturn’s E ring on that day...

Vesta is the largest asteroid visited by a spacecraft. It is currently being observed by NASA's Dawn spacecraft, which has entered orbit around Vesta.
Vesta Sizes Up
NASA's Dawn spacecraft has revealed many landslides on Ceres, which researchers interpret to have been shaped by a significant amount of water ice.

The Cassini spacecraft looks beyond Saturn's limb toward the icy face of Mimas, the innermost of the planet's major moons. This view looks toward the sunlit side of the rings from about 3 degrees ...
Two images of Saturn's A and B ring showcase the opposition effect, a brightness surge that is visible on Saturn's rings when the Sun is directly behind the spacecraft. This view is of the A ring....
