This ASTER image acquired August 11, 2010, shows a massive ice island dominating the center of the image that had broken off of the Petermann Glacier in northwestern Greenland on August 5, 2010. This false-color image of the ice island displays ice in light blue, water as nearly black, and clouds as nearly white.

A study in shades of blue and brown is actually one of the harshest landscapes on Earth. This glimpse of Africa's Sahara Desert, located near where the borders of Mali, Niger, and Algeria converge, is truly a no man's land, a world of sand and rock without roads or settlements.

This abstract in browns and grays from central Algeria shows that some parts of Africa's Sahara Desert contain much more than dunes of wind-blown sand. Barren ridges and fragmented mountains (lower right) border a vast expanse of arid plains etched with a complex system of dry streambeds.

Tin Bider is an ancient and eroded meteor crater on the Tin Rhert Plateau in the Algerian Sahara. Tin Bider is nearly 6 kilometers (3.7 miles) in diameter and was caused by a meteorite impact in this region of northern Africa roughly 70 million years ago. The other streaks near the crater are unrelated to the impact event.

Like a watercolor in which a brushstroke of dark green has bled into a damp spot on the paper, southern Africa's Okavango River spreads across the pale, parched landscape of northern Botswana to become the lush Okavango Delta.

In the American Southwest, transitions from one ecosystem to another can be dramatic and abrupt. This certainly is true in northern Arizona, USA, where the parched Painted Desert, shown here in a palette of purples, adjoins Sitgreaves National Forest (shades of green), a realm of pine woodlands with abundant wildlife.

Landsat 5 image of the Mt. Redoubt area on March 26, 2009 at 1:07 PM AKDT. The false color image shows the large brown ash cloud extending over the Cook Inlet and the western Kenai peninsula (right sid of image). The image also shows a whiter steam and gas plume rising from the summit of Redoubt Volcano (near upper center).

Near the western edge of the Sahara Desert is a feature that resembles a large eye when viewed from space. The Eye of the Sahara, also known as the Richat Structure or Guelb er Richat, is a symmetrical dome of eroded sedimentary and volcanic rock. The outermost rings measure approximately 40 km (25 miles) across.

Central Asia's Tibetan Plateau is justifiably nicknamed "the roof of the world"-its average elevation is more than 4,500 meters (14,764 feet). It is the world's highest and largest plateau, covering an area roughly four times the size of Texas. Tectonic forces have long shaped the Tibetan Plateau's crumpled and uplifted mountain ridges.

During the last ice age, Akimiski Island in Canada's James Bay lay beneath vast glaciers that pressed down with immense force. As the climate changed and the ice retreated, Akimiski began a gradual rebound.

Skeletal extensions of land reach like bony fingers across a section of Liverpool Bay along the northern edge of Canada's Northwest Territories. Only small villages are thinly scattered in this remote and inhospitable region of Arctic tundra bordering the Beaufort Sea.

Straight highways fan out like spokes on a wheel from the Argentine city of San Luis. To the right of the city are croplands that resemble colorful confetti. Founded in 1594, San Luis lies at the tip of the Sierra de San Luis and is largely surrounded by flat-to-rolling fertile plains.
