Pioneer 10 at Jupiter (Artist's Concept)

This image, which is composed of data obtained by NASA's Cassini spacecraft, shows the topography of a mountain known as Janiculum Dorsa on the Saturnian moon Dione.

While the curtain-like auroras we see at Earth are green at the bottom and red at the top, NASA's Cassini spacecraft has shown us similar curtain-like auroras at Saturn that are red at the bottom a...

This mosaic of images from NASA’s Cassini spacecraft shows three fan-like structures in Saturn's tenuous F ring. Such "fans" suggest the existence of additional objects in the F ring. From right t...

This set of enhanced-color maps made from data obtained by NASA's Cassini spacecraft show Saturn's moons Mimas, Enceladus, Tethys, Dione and Rhea. The global maps show the colorful splotches and ba...

A set of eight stickers created from images taken by the Cassini spacecraft.  

Saturn's clouds and hazes at three different levels in the atmosphere are depicted in the image on the right, as observed by the visual infrared mapping spectrometer on the Cassini spacecraft. In ...

This still is from a short computer-animated film that highlights Cassini's accomplishments and Saturn and reveals the science-packed final orbits between April and September 2017.

As Saturn's active moon Enceladus continues to spew icy particles into space, scientists struggle to understand the mechanics of what is going on beneath the fractured south polar terrain. This gra...

Cassini scientists know some of the thousands of images from the spacecraft's journey stand apart. With this feature they present the Cassini Images Hall of Fame. + View Feature

Twenty-eight years before Cassini-Huygens arrived at Saturn, artist Ken Hodges painted this vision of a possible mission to explore Saturn and the giant moon Titan for NASA's Jet Propulsion Laborat...

On Oct. 31, 2008, during the second close flyby of Enceladus of the month, the cameras and other optical remote sensing instruments will be front and center, imaging the fractures that slash across...

Animated view of the last seven years of Cassini orbits.

Presented here is a complete set of cartographic map sheets from a high-resolution Iapetus atlas, a project of the Cassini Imaging Team. The map sheets form a three-quadrangle series covering th...

This graphic shows the trajectories for the Cassini spacecraft during its flybys of the icy moon Enceladus through the 21st planned targeted encounter. With the exception of E-12, E-13, and E-16...

This graphic represents a possible model for mechanisms that could generate the water vapor and tiny ice particles detected by Cassini over the southern polar terrain on Enceladus. This model shows...

A poster version of one of Cassini's famous backlit Saturn images with Earth in the background.

This graphic shows Cassini's final plunge toward Saturn from a top view. 

This still is from a short computer-animated film that highlights Cassini's accomplishments and Saturn and reveals the science-packed final orbits between April and September 2017.

This graphic depicts one possible orbital tour for the Cassini mission. The final four-year tour has yet to be finalized and could look different from this one. The view is from Saturn's north pole...

This composite image of the Sun reveals the entire solar atmosphere in multiple wavelengths.

The Cassini composite infrared spectrometer obtained temperature maps of Saturn's main rings (A, B and C) that showed ring temperatures decreasing with increasing solar phase angle (the change of t...
