At first glance, Saturn's rings appear to be intersecting themselves in an impossible way. In actuality, this view from NASA's Cassini spacecraft shows the rings in front of the planet, upon which ...

Viking 2 Orbiter image of the Martian satellite Deimos taken from 1400 km.

NASA's Dawn spacecraft obtained this image of the surface of asteroid Vesta with its framing camera on August 11, 2011. It was taken through the camera's clear filter. The image has a resolution of...

Light and dark terrain covers the surface of Saturn's moon Iapetus in this Cassini spacecraft image. Lit terrain seen here is on the area between the Saturn-facing side and trailing hemisphere of ...

In Saturn's shadow, the southern hemisphere of Enceladus is lit by sunlight reflected first off the rings and then onto the nightside of the planet. Other sources of illumination include sunlight ...

This close-up view is Cassini's best look yet at Saturn's tenuous innermost D ring. The narrow ringlet visible here is named "D68" and is the innermost discrete feature in the D ring. The image als...

New Horizons took this image of the icy moon Europa rising above Jupiter's cloud tops with its Long Range Reconnaissance Imager (LORRI) at 11:48 Universal Time on February 28, 2007, six hours after...

On the final flyby of Cassini's original four-year tour, its radar mapper captured these unusual channels on Titan at the edge of Xanadu, the widest seen in this area. (For a radar image of Xanadu ...

This radar image of Titan shows a semi-circular feature that may be part of an impact crater. Very few impact craters have been seen on Titan so far, implying that the surface is young. Each new cr...

The first Kuiper Belt Object -- 1992 QB1 -- was discovered in 1992 by American astronomers David Jewitt and Janet Luu using the 2.2-m telescope at Mauna Kea in Hawaii. 

These images from NASA's Dawn spacecraft show Sextilia crater on asteroid Vesta.

This view from NASA's Dawn spacecraft, taken on June 6, 2016, shows Takel Crater (at top left) on Ceres. Takel is 14 miles (22 kilometers) wide and exhibits streaks of bright material on its walls.

This raw, unprocessed image of Saturn's moon Rhea was taken on Jan. 11, 2011, during the “R-3” flyby. The flyby returned Cassini's best imaging of Rhea to date. At closest approach, Cassini flew ju...

Comet 67P/Churyumov-Gerasimenko by Rosetta's OSIRIS narrow-angle camera on 3 August 2014, from a distance of 285 km (177 miles).

The brightest spots on dwarf planet Ceres are seen in this image taken by NASA's Dawn spacecraft on June 6, 2015.

Craters give a rugged look to surface of Iapetus, especially in the large basin of Engelier visible along the southern limb of the moon in this view. The two-toned surface of the moon is evident i...

This animated graphic shows how Saturn and its moon Enceladus are electrically linked. Magnetic field lines, invisible to the human eye but detectable by the fields and particles instruments on NAS...

The F ring shepherd moon Prometheus touches the face of Saturn once more before moving off into blackness and continuing in its orbit.

Day and Night on Hyperion October 22, 2004 Full-Res: PIA06504 As it approached Saturn near the end of its second orbit, Cassini caught...

Only Cassini could provide this enchanting, natural color view of crescent Saturn, which gazes down onto the unlit side of the planet's spectacular rings. The robotic ship plies the peaceful black ...

This image from NASA's Dawn spacecraft shows the center of Datan Crater on Ceres. Datan measures about 40 miles (60 kilometers) in diameter.

This view from NASA's Dawn mission shows Ceres' tallest mountain, Ahuna Mons. A significant amount of sodium carbonate has been found, shown in green and red colors in the lower right image.

Saturn's north pole is littered with storms, as we see in this color view of the pole. A bit of the north polar hexagon is also visible at the upper-right. Cassini scientists are looking forward...

Using a special spectral filter, the high-resolution camera aboard NASA's Cassini spacecraft was able to peer through the hazy atmosphere of Saturn's moon Titan.

Although the crack-like features seen here on Dione's surface appear wispy and faded, they are in reality a series of geologically fresh fractures!
