Great Dark Spot
Within the windswept wastes of Titan's equatorial dune desert lies the 1,700-km (1,050-mi) wide bright region called Adiri, seen here at center. The intrepid Huygens probe landed off the northeaste...
Only a slice of Iapetus is illuminated in this image, but still the Cassini spacecraft spies the distinctive two-tone surface of this distant Saturnian moon. Lit terrain seen here is on the leadin...
Cassini spied a crater-covered Dione in this image from Dec. 8, 2004. The bright, wispy streaks for which Dione is known are located on the moon's night side to the west. The streaky terrain was im...
A world whose mysteries are just coming to light, Enceladus has enchanted scientists and non-scientists alike. With its potential for near-surface liquid water, the icy moon may be the latest addit...
Pan is nearly lost within Saturn's rings in this view that captures a small section of the rings from just above the ringplane. Pan (28 kilometers, or 17 miles across) appears a small bright dot o...
Lost Among Rings
Cassini kicked off the year with a successful flyby of Titan on Jan. 15. Cassini will add to the wealth of data with new vistas during 13 Titan flybys planned for this year. Raw images from the mos...

Titan's First Close-Up October 26, 2004 This image is one of the closest ever taken of Saturn's hazy moon Titan. It was captured by Cassini's imaging scien...
Titan's First Close-Up
This dramatic close-up of Tethys shows the large crater Penelope lying near center, overprinted by many smaller, younger impact sites. Three smaller impact features of roughly similar size make ...
This view of Ceres, taken by NASA's Dawn spacecraft on December 10, 2015, shows an area in the southern mid-latitudes of the dwarf planet.
Dawn's Lowest Orbit: Southern Mid-Latitudes
The three mosaics shown here were composed with data from Cassini's visual and infrared mapping spectrometer taken during the last three Titan flybys, on Oct. 28, 2005 (left image), Dec. 26, 2005 (...
Mapping Titan's Changes
Dramatic differences between dark and light embellish this Cassini spacecraft image of Saturn, its rings and its moons Dione and Enceladus. Saturn's northern and southern latitudes appear dark in ...
Brightness Bucks the Dark
Saturn's rings occupy the space between two of the planet's moons in this image which shows the highly reflective moon Enceladus in the background and the smaller moon Janus in the fore. Janus (17...
The Space Between
Titan's swirling south-polar vortex stands out brightly against the other clouds of the south pole (seen at the lower right of the image). The Cassini spacecraft is monitoring the development of t...
Cassini made a close flyby of Saturn's moon Iapetus on Sept. 10, 2007, and the visual and infrared mapping spectrometer obtained these images showing surface composition and particle size. The vis...
Tiny Grains on Iapetus
This image from NASA's Dawn spacecraft shows Arruntia crater, located in asteroid Vesta's Bellicia quadrangle, in Vesta's northern hemisphere.
Seven images capture the 2015 supermoon lunar eclipse.
Supermoon Lunar Eclipse Sequence (2015)
The magnetosphere is an area of space, around a planet, that is controlled by that planet's magnetic field. Saturn is surrounded by a giant magnetic field, lined up with the rotation axis of the ...

An emerging idea, bolstered by three decades of science, is that there are "Goldilocks stars" — not too hot, not too cool, and above all, not too violent to host life-friendly planets.
