Io Color Eclipse

Cassini's radar instrument finds lakes in the southern hemisphere of Titan during the most recent Titan flyby. This is the first confirmation of lakes in the southern hemisphere with the radar ins...

This image from NASA's Dawn spacecraft shows the brightest area seen on asteroid Vesta so far. It shows a crater located inside the rim of the Rheasilvia basin at the south pole of Vesta.

Saturn's moon Janus orbits in front of the rings, which are partially darkened by the shadow of the planet in this Cassini spacecraft view. Saturn's shadow obscures about half the rings. This can ...

Atmosphere and Enceladus October 28, 2004 Full-Res: PIA06508 Saturn's southern atmosphere looms before Cassini, displaying rich detail...

Long streamers of cloud encircle the south polar region of Saturn. Farther poleward, or toward lower left, faint, deeper atmospheric structures lurk beneath the haze. This image was acquired from ...

The shadow of Saturn's moon Dione, cast onto the planet, is elongated in dramatic fashion. The moon itself does not appear here, but the shadow can be seen south of the ringplane. This view looks ...

The Cassini orbiter has revealed many surprises within the Saturn system, including the possible presence of a ring of debris surrounding the ancient heavily cratered surface of Rhea, Saturn's ...

SDO collected images of the rarest predictable solar event—the transit of Venus across the face of the Sun in 2012.

Telescopes, telephone and tablets at the ready, a group of amateur astronomers gathers under twilight skies to wave at Saturn on July 19, 2013. Their gathering in the town of Kendal in England's Cu...

+ View Movie Prometheus zooms across the Cassini spacecraft's field of view, attended by faint streamers and deep gores in Saturn's F ring. This movie sequence of five images shows the F ring shep...

During its very close flyby on March 9, 2005, the Cassini spacecraft captured this false-color view of Saturn's moon Enceladus, which shows the wide variety of this icy moon's geology. Some geologi...

This detailed view of Saturn's mid-B ring shows intriguing structure, the cause of which has yet to be explained by ring scientists. The image shows a radial location located between approximately ...

This image of Eutropia AV-L-10, 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 full-frame view of asteroid Vesta was obtained by NASA's Dawn spacecraft with its framing camera on July, 24 2011. This image was taken through the camera's clear filter. The image has a resol...

A large dark region fills a semicircle of the visible disk of Iapetus on the left of this Cassini spacecraft image, appearing like a bite taken out of this Saturnian moon. See Global View of Iapet...

NASA's Dawn spacecraft shows densely cratered terrain near Vesta's terminator on August 6, 2011. This image was taken through the framing camera's clear filter aboard the spacecraft. North is point...

High-mass stars are important because they are responsible for much of the energy pumped into our galaxy over its lifetime. 

Encircled in purple stratospheric haze, Titan appears as a softly glowing sphere in this colorized image taken one day after Cassini's first flyby of the moon on July 2, 2004. This image shows a t...

Swirling clouds drift like phantoms in Saturn's murky depths. The camera filter used for this image captures light at wavelengths where atmospheric gases like methane are fairly transparent, allow...

The southern hemisphere of Saturn's moon Tethys is seen in this polar stereographic maps, mosaicked from the best-available images obtained by NASA's Cassini spacecraft. The map is centered on the...

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...

If your eyes could only see the color red, this is how Saturn's rings would look.

Titan's Tantalizing Streaks October 28, 2004 Full-Res: PIA06985 This wide-angle image captured by Cassini's imaging science subsystem sho...

The face of Dione is almost fully lit as the Cassini spacecraft flies in between this moon and the sun with Dione at low phase. With a few hundred pixels of its digital camera, Cassini details do...

This map of Saturn's moon Titan shows the location of the upcoming April 30, 2006, Titan flyby and the areas mapped so far by the Cassini radar mapper using its synthetic aperture radar imaging mod...
