Vivid colors and bizarre shapes come together in this artistic, fantastical image, taken from space on June 15, 2005. The labyrinth of exotic features was spotted along the edge of Russia's Chaunskaya Bay (shown by the vivid blue half circle) in northeastern Siberia. Two major rivers, the Chaun and Palyavaam, flow into the bay, which in turn opens into the Arctic Ocean. Ribbon lakes and bogs are present throughout the area, created by depressions left by receding glaciers.

These night-shining clouds were spotted over Billund, Denmark on July 15, 2010. These rare clouds are technically called "noctilucent" or "polar mesospheric" clouds, and form at high altitudes, 80 to 85 kilometers (50 to 53 miles) high, where the mesosphere is located. The clouds' high position in the atmosphere allows them to reflect sunlight long after the sun has dropped below the horizon. They only form when the temperature drops below –130 degrees Celsius (-200 degrees Fahrenheit), whereupon the scant amount of water high in the atmosphere freezes into ice clouds. This happens most often in countries at high northern and southern latitudes (above 50 degrees) in the summer, when the mesosphere is coldest. Studies suggest that night-shining clouds are becoming brighter and more common, which is linked to the mesosphere getting colder and more humid. These changes may be happening because of increased levels of heat-trapping greenhouse gases such as carbon dioxide and methane in the atmosphere. In the mesosphere, carbon dioxide radiates heat into space, causing cooling. More methane, on the other hand, puts more water vapor into the atmosphere, because sunlight breaks methane up into water molecules at high altitudes. Research is ongoing.

This scar on an arid landscape is the dry riverbed of the Ghadamis River in the Tinrhert Hamada Mountains near Ghadamis, Libya. This image was acquired by the Landsat 7 satellite on November 6, 2000. This is a false-color composite image made using near-infrared, green, and blue wavelengths. The image has also been sharpened using the sensor’s panchromatic band.

The United States' first spacewalk, made by Ed White on June 3, 1965 during the Gemini 4 mission. On the third orbit, White opened his hatch and used a hand-held manuevering oxygen-jet gun to push himself out of the capsule. After the first three minutes the fuel ran out and White manuevered by twisting his body and pulling on the tether. His extra-vehicular activity started over the Pacific Ocean near Hawaii and lasted 23 minutes, ending over the Gulf of Mexico. The photograph was taken by commander James McDivitt.

Dagze Co (Lake) is one of many inland lakes in Tibet. In glacial times, the region was considerably wetter, and lakes were correspondingly much larger. This is evident by the numerous fossil shorelines that circle the lake, and attest to the presence of a larger, deeper lake. Changes in climate have resulted in greater aridity of the Tibetan Plateau, and drying up of the lakes. Image taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on October 8, 2001.

This image, taken on 4 July 2002, shows spiraling eddies known as von Karman vortices over Alaska’s Aleutian Islands. Such eddies form as air flows over and around objects in its path. In this case, these eddies were created when prevailing winds sweeping east across the northern Pacific Ocean encountered Alaska’s Aleutian Islands.

'Ship tracks' above the northern Pacific Ocean. These patterns are produced when fine particles from ship exhaust float into a moist layer of atmosphere. The particles seed new clouds or attract water from existing cloud particles. Image taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Aqua satellite on July 3, 2010.

This photo, taken on January 22, 2001 by the Landsat-7 satellite, shows Akpatok Island, which lies in Ungava Bay in Canada. Accessible only by air, Akpatok Island rises out of the water as sheer cliffs that soar 500 to 800 feet (150 to 243 meters) above the sea surface. The island is an important sanctuary for cliff-nesting seabirds. Numerous ice floes around the island attract walruses and whales, making Akpatok a traditional hunting ground for native Inuit people.

This beautiful image, taken on 11 January 2001, shows a geological formation in the Maur Adrar Desert in Mauritania, Africa. Known as the "Richat Structure," this snail-shell-like formation was created when a volcanic dome hardened and gradually eroded, exposing onion-like layers of rock.

In this image, it’s hard to get a sense of scale or of what we’re actually looking at. This picture, taken by the Landsat-5 satellite on 8 April, 1985, shows sand dunes (yellow streaks) that extend from Algeria into Mauritania in northwest Africa. These wind-blown sand ridges make up Erg Iguidi, one of the Sahara’s ‘sand seas’ in which individual dunes are often more than a third of a mile (500 meters) wide and tall.

This iconic image speaks volumes. To many it underscores the vastness of space, the loneliness of the cosmos and how fragile our home planet really is. Entitled “Earthrise,” it was taken by astronaut William Anders during an orbit of the moon as part of the Apollo 8 mission. Apollo 8 was the first manned mission to the moon, which entered the Moon’s orbit on Christmas Eve 1968. That evening, the astronauts onboard held a live broadcast, in which they showed pictures of the Earth and moon as seen from their spacecraft. Command Module Pilot Jim Lovell said, "The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth." The astronauts ended the broadcast with the crew taking turns reading from the book of Genesis.

This photo from NASA’s Curiosity rover shows the Earth as seen from the surface of Mars, shining brighter than any star in the Martian night sky. Earth is the bright point of light a little left of the image’s center and our moon can be seen just below Earth. Curiosity, which landed on the red planet on August 6, 2013, is the largest and most advanced rover ever sent to Mars. It studies the geology of its surroundings and has found evidence of a past environment well-suited to support microbial life. Researchers used the left-eye camera of Curiosity's Mast Camera (Mastcam) to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (January 31, 2014). The image has been processed to remove cosmic-ray effects. A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct bright evening ‘stars’. When Curiosity took the photo, Earth was about 99 million miles (160 million kilometers) from Mars. This picture adds to our collection of photos of planet Earth from afar, giving a unique perspective to our place in the cosmos.

This interesting image shows the world’s largest glacier, Lambert Glacier in Antarctica, and icefall that flows into it. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow descent 1300 feet (400 meters) to the glacier below. The image was taken by the Landsat-7 satellite on December 2, 2000 and is a false-color composite made from infrared, red and green wavelengths. The image has also been sharpened using the sensor’s panchromatic band.

This false-color image shows snow-capped peaks and ridges of the eastern Himalayas between major rivers in southwest China. The Himalayas are made up of three parallel mountain ranges that together stretch for more than 1800 miles (2,900 kilometers). This particular image was taken by NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard the Terra satellite, on February 27, 2002. The picture is a composite made by combining near-infrared, red and green wavelengths.
