. Mesas of dry ice at the martian south pole retreat by about 10 feet (3 meters) per Mars year. This sequence of Mars Global Surveyor images shows changes in the same south polar region from 1999 to 2005. Dry ice sublimates at the mesa scarps, but no new ice is being deposited.

The Spitzer Space Telescope's GLIMPSE catalog consists of some 30 million infrared sources along the galactic equator. This plot shows the number of sources in two strips on either side of the galaxy's center, from 10° to 22° (top) and 350° to 338° galactic longitude. The highest density of sources — about 23,000 per square degree — appears as red; lower densities map as progressively cooler colors. ...

. Mars Global Surveyor discovered new gullies that formed on a sand dune west of Mars' Hellas Basin. Researchers think the gullies were created when buried patches of dry ice sublimated, causing the overlying sand to flow like a fluid. Click here for an animation. NASA / JPL / MSS

. This infrared photograph taken with NASA's Spitzer Space Telescope revealed a never-before-seen dust ring deep within the Andromeda galaxy (highlighted by the inset). When combined with a previously observed outer ring, the presence of both dust rings suggests that M32 plunged through the disk of Andromeda along Andromeda's polar axis approximately 210 million years ago.

... The colors indicate the relative motions of galaxies with accurately measured distances, with shades of green and blue indicating motions toward us and shades of yellow to red indicating motions away from us. Our nearest neighbors have only small relative motions (represented by yellows and greens), as seen best in the exploded view of the right panel. We, along with all these nearest neighbors, are moving together toward the lower right corner of the figures. ...

This colorful display shows tiny differences (or "anisotropies") in the Cosmic Microwave Background (CMB) over the entire sky. The average temperature is just 2.73 kelvins (2.73 degrees Celsius above absolute zero), and the temperature differences span mere millionths of a degree. ... Until now, part of the Milky Way's motion inferred from the variation in the CMB was unexplained. Astronomers have discovered that the Milky Way and neighboring galaxies are being pushed from the Local Void. ...

This diagram shows the ingredients of the universe. Astronomers have recently realized that the main ingredient is "dark energy," a mysterious form of energy that exists between galaxies and forces the universe to expand at an ever-increasing rate. The next-largest constituent is "dark matter," which is an unknown form of matter. The rest of the universe consists of ordinary matter, most of which is locked up in stars and clouds of gas. ...
