This picture of Eros, the first of an asteroid taken from an orbiting spacecraft, is a mosaic of four images obtained by NEAR on February 14, 2000, immediately after the spacecraft's insertion into...

This image from NASA's Dawn spacecraft is centered on a small, young, fresh crater with bright and dark ejecta rays extending from it. The crater is located in Vesta's Tuccia quadrangle on asteroid...

This image of a small crater north of Ceres' Datan Crater was obtained by NASA's Dawn spacecraft on June 9, 2018 from an altitude of about 48 miles (77 kilometers).

The dark Cassini Division, within Saturn's rings, contains a great deal of structure, as seen in this color image. The sharp inner boundary of the division (left of center) is the outer edge of the...

This true color picture was assembled from Voyager 2 Saturn images obtained August 4, 1981 from a distance of 21 million kilometers (13 million miles) on the spacecraft's approach trajectory. T...

Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.

Cassiopeia A (Cas A) is the remnant of a massive star that exploded about 300 years ago. The X-ray image shows an expanding shell of hot gas produced by the explosion.

A meteor streaks across the sky during the annual Perseid meteor shower.

Data from NASA's Cassini spacecraft have enabled scientists to make the highest-resolution heat intensity maps yet for the hottest part of a ''tiger stripe'' fissure on Saturn's moon Enceladus. The...

After more than 13 years at Saturn, and with its fate sealed, NASA's Cassini spacecraft bid farewell to the Saturnian system by firing the shutters of its wide-angle camera and capturing this last,...

A fresh look at Saturn's moon Enceladus reveals tempting new details about the brightest real estate in the solar system. This false-color image shows that some of the linear features on Enceladus ...

This image obtained by NASA's Dawn spacecraft shows a subtle feature on Ceres called Kwanzaa Tholus. The rounded shape of Kwanzaa Tholus is typical of tholi.

NASA's Pioneer 10 was the first spacecraft to obtain close-up images of Jupiter, and three of its largest moons: Ganymede, Callisto, and Europa. 

Close Up on Titan's Mid-Latitude Clouds December 16, 2004 Full-Res: PIA06157 Images taken during Cassini's second close approach to Tit...

An artist's conception of an impact event on asteroid Pallas. 

This image of Saturn's moon Titan from the Synthetic Aperture Radar instrument on the Cassini spacecraft shows Shikoku Facula, a region that is bright in both radar and visible wavelengths. This r...

This image shows a close-up of long, narrow, sinuous gullies that scientists on NASA's Dawn mission have found on the giant asteroid Vesta. The crater shown here is called Cornelia.

The vast hydrocarbon seas and lakes (dark shapes) near the north pole of Saturn's moon Titan sprawl out beneath the watchful eye of NASA's Cassini spacecraft.

A whimsical artist's concept captures the spirit of NASA's Voyager mission.

Second Titan Targeted Flyby #3 December 13, 2004 Full-Res: PIA06153 This image was taken during Cassini's very close approach to Titan ...

With kaleidoscopic forms and hues, these two false-color views from NASA's Cassini spacecraft show the patterns that come and go in the course of one Saturn day within the huge storm in the planet'...

Three different views of the Martian moon Phobos, as seen by NASA's 2001 Mars Odyssey orbiter using its infrared camera.

The existence of oceans or lakes of liquid methane on Saturn's moon Titan was predicted more than 20 years ago.
