Great Red Spot

A quintet of Saturn's moons come together in the Cassini spacecraft's field of view for this portrait.

The Cassini spacecraft presents a tempestuous scene in which the clouds of Saturn's bright equatorial region entwine with those in darker, southerly latitudes. See Seeing High in the Sky for a pre...

Titan's Polar Streak November 1, 2004 Full-Res: PIA06510 This image shows Titan, Saturn's largest moon (5,150 kilometers, or 3...

In this ten-second exposure, a meteor streaks across the sky above Washington, DC during the annual Perseid meteor shower, Thursday, Aug. 13, 2015, in Arlington, Va.

These images from NASA's Dawn spacecraft are located in asteroid Vesta's Numisia quadrangle, in Vesta's northern hemisphere. The bottom part of the rim of Fabia crater is much fresher than the top ...

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 image from NASA's Dawn spacecraft, is based on a framing camera image that is overlain by a color-coded height representation of topography. This heart-shaped hollow is roughly 10 kilometers (...

This image from NASA's Dawn spacecraft shows many linear and curvilinear grooves running roughly diagonally across asteroid Vesta's Gegania quadrangle.

Inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida, OSIRIS-REx is prepared for encapsulation in its payload fairing.

This view of Ezinu Crater on Ceres was taken by NASA's Dawn spacecraft on Oct. 19, 2015. Ezinu is the large crater in the top left corner of the image and contains a canyon-like feature near its ce...

This image of dwarf planet Ceres, taken by NASA's Dawn spacecraft on June 15, 2015, shows a cluster of mysterious spots that are clearly brighter than their surroundings. Dawn took this image at an...

This view of the volcanic plains of Neptune's moon Triton was produced using topographic maps derived from images acquired by NASA's Voyager spacecraft during its August 1989 flyby, 20 years ago th...

As it swooped past the south pole of Saturn's moon Enceladus on July 14, 2005, Cassini acquired high resolution views of this puzzling ice world. From afar, Enceladus exhibits a bizarre mixture of ...

+ View Full-Res This image was obtained by Cassini's radar instrument during a flyby on Jan. 13, 2007. The radar antenna was pointing toward Titan at an altitude of 1,000 kilometers (621 miles) ...

NASA's Cassini spacecraft obtained this unprocessed image of Saturn's moon Helene on June 18, 2011. This image has not been validated or calibrated. A validated/calibrated image will be archived w...

The shadow of the moon Tethys is cast onto Saturn's A ring, almost blanketing the Enke Gap. The novel illumination geometry created as Saturn approaches its August 2009 equinox allows moons orbiti...

This frame from an animation from NASA's Dawn spacecraft shows a crater in the northern polar region of Ceres that is partly in shadow year-round, where bright water ice deposits have been observed...

Images from Dawn's visible and infrared mapping spectrometer (VIR) show a portion of Ceres' cratered northern hemisphere, taken on May 16, 2015.

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

The brightly lit limb of a crescent Enceladus looks ethereal against the blackness of space. The rest of the moon, lit by light reflected from Saturn, presents a ghostly appearance.

Ominous Giant November 26, 2004 Full-Res: PIA06530 Saturn's massive atmosphere appears poised to crush little Enceladus in this im...

The projection of Saturn's shadow on the rings grows shorter as Saturn’s season advances toward northern summer, thanks to the planet's permanent tilt as it orbits the sun. 

The Cassini spacecraft peers down through the hazy atmosphere of Saturn's moon Titan to view the dark region called Belet. This image was captured using a spectral filter sensitive to wavelengths ...
