This image, taken on 10 May 2001, shows one of the islands of New Caledonia, an archipelago 1200 kilometers (750 miles) east of Australia. New Caledonia contains the world’s third-largest coral reef structure, and its coral reefs support an unusually large diversity of species, including many predators, big fish, turtles, and the world’s third-largest dugong population. (Dugongs are large marine mammals.) In this natural-color image, the islands appear in shades of green and brown — mixtures of vegetation and bare ground. The surrounding waters range from pale aquamarine to deep blue, and the color differences reflect varying water depths. Over coral reef ridges and sand bars, the water is shallowest and palest in color.

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.

Some of the most breathtaking views of Earth taken from space are those that capture our planet's limb. When viewed from the side, the Earth looks like a flat circle, and the atmosphere appears like a halo around it. This edge of the atmosphere is known as the limb. Viewed from space, the image of this luminous envelope of gases shielding life on our planet from the dark, cold space beyond rarely fails to fascinate us. What makes this image even more fascinating is the added silhouette of the space shuttle Endeavour. The orange layer seen is the troposphere, where all of the weather and clouds that we typically experience are created and contained. The troposphere gives way to the whitish stratosphere and then mesosphere. This image was captured by an astronaut prior to Endeavour's rendezvous and docking with the International Space Station on February 9, 2010.

'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.

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 simulated natural color image shows the Coco River, between Nicaragua and Honduras, as seen from space on December 5, 2002. As it makes its way to the Caribbean Sea, the Coco River forms the border between the two countries. The coastline, known as the Mosquito Coast, is of low relief and has plentiful water bodies, relic shorelines and high temperatures. Mosquito Coast derives its name from its principal inhabitants, the Miskito Indians, whose name was corrupted into Mosquito by European settlers. The Mosquito Indians, of whom there are several tribes, are short in stature and very dark-skinned. The first European settlement in the Mosquito country started in 1630, when agents of the English-chartered Providence Company established friendly relations with the local inhabitants. The image shown covers an area of 29 x 39 kilometers (18 x 24 miles).

Manam Volcano in Papua New Guinea, as seen from space on June 16, 2010. Located 13 kilometers (8 miles) off the coast of mainland Papua New Guinea, Manam forms an island 10 kilometers (6 miles) wide. It is a stratovolcano. The volcano has two summit craters, and although both are active, most historical eruptions have arisen from the southern crater. On June 16, the volcano released a thin, faint plume as clouds clustered at the volcano's summit. Rivulets of brown rock interrupt the carpet of green vegetation on the volcano’s slopes. White clouds partially obscure the satellite’s view of Manam. The clouds may be the result of water vapor from the volcano, but they may also have formed independently of volcanic activity. The volcanic plume appears as a thin blue-gray veil extending toward the northwest over the Bismarck Sea.

Lake Chad, Africa; February 7 and 11, 2004. Once serving as part of the floor for a much larger Lake Chad, the area now known as the Bodele Depression, located at the southern edge of the Sahara Desert in north central Africa, is slowly being transformed into a desert landscape. In the mid-1960s, Lake Chad was about the size of Lake Erie. But persistent drought conditions, coupled with increased demand for freshwater for irrigation, have reduced Lake Chad to about 5 percent of its former size. As the waters receded, the silts and sediments resting on the lakebed were left to dry in the scorching African sun. The small grains of the silty sand are easily swept up by the strong wind gusts that occasionally blow over the region. Once heaved aloft, the dust can be carried for hundreds or even thousands of kilometers. The remnants of Lake Chad appear in olive-green amid the tan and light brown hues of the surrounding landscape where the countries of Chad, Niger, Nigeria and Cameroon all share borders. The Bodele Depression was the source of some very impressive dust storms that swept over West Africa and the Cape Verde Islands in February 2004, the date of this image.

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.

Susitna Glacier, Alaska. Like rivers of liquid water, glaciers flow downhill, with tributaries joining to form larger rivers. But where water rushes, ice crawls. As a result, glaciers gather dust and dirt, and bear long-lasting evidence of past movements. Alaska’s Susitna Glacier reveals some of its long, grinding journey in this image, taken from space on August 27, 2009. The satellite image combines infrared, red and green wavelengths to form a false-color picture. Vegetation is red and the glacier’s surface is marbled with dirt-free blue ice and dirt-coated brown ice. Infusions of relatively clean ice push in from tributaries in the north. The glacier surface appears especially complicated near the center of the image, where a tributary has pushed the ice in the main glacier slightly southward. In the lower left corner of this image, meltwater lakes can be seen on top of the ice.

The Dasht-e Kevir, or Great Salt Desert, is the largest desert in Iran. It is primarily uninhabited wasteland, composed of mud and salt marshes covered with crusts of salt that protect the meager moisture from completely evaporating. This image was taken by the Landsat 7 satellite on October 24, 2000. It is a false-color composite image made using infrared, green and red wavelengths. The image has also been sharpened using the sensor’s panchromatic band.

This map shows the bright lights of cities and wildfires set against the inky black backdrop of night. The image is actually a composite of satellite data collected over a number of days in April 2012 and October 2012, and is the result of 312 orbits and 2.5 TB of information. The lights seen here are not just from cities; they are also from wildifires, lightning, gas flares and reflected moonlight. Because the image is a composite of several days’ worth of data, fires and other points of light may have been picked up by the satellite and integrated into the composite image even though they were temporary, making some rural locations (such as in Australia) seem brighter than they really are on a typical day.
