Gypsum, a common mineral composed of calcium sulfate, lies scattered in this newly-released image of the Olympia Undae region of Mars. ... Made on October 1, 2006, the image covers about 12 square kilometers (7.5 sq. mi.) Gypsum, used commonly on Earth as the substance in wallboard, is a sulfate-rich mineral that forms by evaporation and requires large amounts of water for its formation. In this image, brighter areas contain more gypsum and darker areas less so. ...

. This new NASA Hubble Space Telescope image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. During the course of the collision, billions of stars will be formed. The brightest and most compact of these star birth regions are called super star clusters. The new image allows astronomers to better distinguish between the stars and super-star clusters created in the collision of two spiral galaxies. NASA, ESA, the Hubble Heritage Team (STScI/AURA)-ESA

Dust and debris parade in an extremely misshapen ring around the young star, HD 15115. The disk, seen edge-on with NASA's Hubble Space Telescope, is the dense blue line extending from the star to the upper right and lower left of the image. The disk appears thicker at upper right than at lower left, evidence of its lopsided structure. Astronomers think the disk's needle-like look is caused by dust particles following a highly elliptical orbit around the star. ...

. NASA's Hubble Space Telescope imaged Abell 2218, a giant cluster of galaxies and the best example of a natural gravitational lens. The cluster is so massive that its enormous gravitational field deflects light rays passing through it, magnifying and brightening images from faraway objects. Astronomers announced this week the discovery of distant galaxies, found using gravitational lensing. NASA Goddard Space Flight Center

. Caltech astronomers used foeground clusters of galaxies as 'natural telescopes' to boost faint signals from the most distant sources. Typical magnification factors are 20 times, thereby bringing into view young galaxies that would otherwise be unobservable. This technique has allowed Caltech astronomers to locate a new population of early feeble sources, which may be sufficiently numerous to be responsible for drawing the so-called Dark Ages to a close.

. In this magnified image captured by the Mars Reconnaissance Orbiter, the Pathfinder lander is clearly visible in silhouette, including its airbags and the ramp that the Sojourner rover rolled down to reach the surface. Various named rocks and landscape features are indicated, as well as the possible site of the Sojourner rover, about 20 feet (6 meters) due south of the lander. NASA/JPL/Univ. of Arizona/USGS

. From July 12 until July 31, two NASA Ames K10 rovers, "Red" (above) and "Black," will perform surveys of several simulated lunar outpost sites, including a region called "Drill Hill" in the Arctic Circle. The rovers will carry ground-penetrating radar to map subsurface structure and a 3-D scanning laser to map terrain topography. Provided by NASA

On September 11, 2007, NASA's Mars Exploration Rover Opportunity entered Victoria Crater on the rover's 1,291st martian day, or sol. The rover team commanded Opportunity to drive just far enough into the crater to get all six wheels onto the inner slope, and then to back out again and assess how much the wheels slipped on the slope. ... The left half of the image looks across an alcove informally named "Duck Bay" toward a promontory called "Cape Verde" clockwise around the crater wall. ...
