. "Cat scratches," believed to be windblown dunes, appear in this radar image returned by the Cassini spacecraft of Saturn's moon Titan. Individual dunes measure up to .6 mile (1 kilometer) long and are oriented east-west. NASA / JPL

. Saturn's rings from the inside out: The Cassini Division at left (faint red) is followed by the A ring in its entirety. The A ring begins with a reddish interior, indicating a greater proportion of dirt, followed by more turquoise тАФ ice тАФ at greater distances from the planet. The red band roughly three-fourths of the way outward in the A ring is known as the Encke Gap. NASA / Univ. Colorado, LASP

. Pack-ice-like plates cover the ground in Mars' southern Elysium Planitia, a possible relic of an ice-covered sea. A team of planetary geologists thinks some of the ice probably is still in the ground. The image frame spans about 25 miles (40 km), and the scale of the features matches that of pack ice on Earth.

. Saturn and its rings completely fill the field of view of Cassini's narrow angle camera in this natural color image taken on March 27, 2004. This is the last single "eyeful" of Saturn and its rings achievable with the narrow angle camera. From now until orbit insertion, Saturn and its rings will be larger than the camera's field of view.

. Water sources beneath Cerberus Fossae likely created the torrent required to form Athabasca Valles, perhaps in repeated floods. About 1,000 feet (300m) separates the highest and lowest elevations on this map, where redder colors indicate higher elevations. Courtesy of Mark Manga

. This artist's conception shows a dwarf galaxy seen from the surface of a hypothetical exoplanet. A new study finds that the dark matter in dwarf galaxies is distributed smoothly rather than being clumped at their centers. This contradicts simulations using the standard cosmological model known as lambda-CDM. Credit: David A. Aguilar (CfA)

. Cassini has captured the best image ever of Saturn's inner moon Epimetheus. In this false-color view, the slightly reddish feature at lower left is a crater named Pollux. Hilairea, the large crater just below center, has a diameter of 21 miles (33 kilometers). NASA / JPL / SSI

. NASA's Mars Exploration Rover Opportunity has found an iron meteorite on Mars, the first meteorite of any type ever identified on another planet. The pitted, basketball-size object is mostly made of iron and nickel. Readings from spectrometers on the rover determined that composition. Opportunity used its panoramic camera to take the images used in this approximately true-color composite on the rover's 339th martian day, or sol (Jan. 6, 2005). NASA/JPL/Cornell

. Scientists think Cerberus Fossae erupted about 5 million years ago, spewing water and volcanic ash. In their model, the water drained southwest through Athabasca Vallis and ponded in the region shown. The water quickly developed a covering of pack ice mixed with volcanic ash which slowed its evaporation. Some ice may still remain under the ash layer. NASA / JPL / USGS

. After undergoing a catastrophic collision, the color of an asteroid gets modified rapidly by the solar wind so that it resembles the mean color of extremely old asteroids. After the first million years, the surface тАЬtansтАЭ much more slowly. At that stage, the color depends more on composition than on age. ESO/M. Martins
