The crew of Expedition 13 recently passed a major milestone: as of late August 2006, more than one quarter of a million images of Earth had been taken from the International Space Station. The rate at which Expedition 13 has been photographing the Earth has been record-setting, as they passed the www.nasa.gov/mission_pages/station/science/240000_pix.html 200,000 th image mark less than two months before.

Along the coast of Dubai -- one of several emirates comprising the United Arab Emirates -- are human-made islands. When the Advanced Spaceborne Thermal Emission and Reflection Radiometer asterweb.jpl.nasa.gov (ASTER) on NASA's terra.nasa.gov Terra satellite took this picture on September 18, 2006, these islands were the largest artificial islands in the world. All of the islands were still under some degree of en.wikipedia.org/wiki/Palm_Islands construction in the fall of 2006. From south to...

Resembling a work of modern art, variegated green crop circles cover what was once shortgrass prairie in southwestern Kansas. The most common crops in this region -- Finney County -- are corn, wheat, and sorghum. Each of these crops was at a different point of development when the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( asterweb.jpl.nasa.gov/ ASTER ) captured this image on June 24, 2001, accounting for the varying shades of green and yellow. Healthy, growing crops are...

Each of these swirling clouds is the result of a meteorological phenomenon known as a von Karman vortex. These vortices appeared over Alexander Selkirk Island in the southern Pacific Ocean. Rising precipitously from the surrounding waters, the island's highest point is nearly a mile (1.6 km) above sea level. As wind-driven clouds encounter this obstacle, they flow around it to form large, spinning eddies. This image was acquired by landsat7.usgs.gov/ Landsat 7's Enhanced Thematic Mapper plus...

For almost 2,000 years, the River Thames has served as the life force of London, capital of the United Kingdom and one of the world's most famous cities. In AD 43 the Romans established the trading settlement of Londinium at a favorable crossing point on the river. The Romans remained until the 5th century, when the city came under Saxon control. The early 17th century saw enormous growth, but the deadly plague of 1664 and 1665 ravaged the population, and in the following year the Great Fire,...

The skies over Hispaniola opened up on May 24, 2004, and poured as much as 10 inches (25 cm) of rain within a 24-hour span onto an already rain-soaked island that had received as much as 10 inches of rain over the previous week. The torrent triggered flooding and mudslides that ran swiftly down the northern and southern flanks of the Massif de la Salle, straddling the border between Haiti and the Dominican Republic. As the deluge fanned out on the flood plains below, several villages were...

Human history isn't confined to books; some of it is written across the surface of the Earth. Among the places where the earth itself tells a story of our past is the French landscape around the city of Verdun, where more than 300,000 French and Germans died during a World War I battle that went on from mid-February to mid-December 1916.

Kiev (also spelled Kyiv) is the capital of Ukraine, the second largest country in Europe (second only to Russia and slightly larger than France). The city's history has long been entwined with Russia's. In the region's early history, Kiev was the capital city of a state that encompassed much of the surrounding lands. Invaded by the Mongols in the 13th century, Kiev fell from primacy, but rebuilt itself and remained a major city power for centuries. It became the capital of the newly independent...

Jupiter's moon Europa has a crust made up of blocks, which are thought to have broken apart and 'rafted' into new positions, as shown in the image on the left. These features are the best geologic evidence to date that Europa may have had a subsurface ocean at some time in its past. Combined with the geologic data, the presence of a magnetic field leads scientists to believe an ocean is most likely present at Europa today.

Before the late eighteenth century, residents of England didn't necessarily take much interest in the rocks under their feet. The arrival of the Industrial Revolution, however, drew the attention of the country's entrepreneurs downward. England's industrialists began plunging deep underground for coal -- the fossilized remains of ancient swamps -- and carving canals across the countryside to transport it efficiently.

In the heart of the Australian Outback, a massive block of red sandstone rises up out of the near-perfect flatness of the eroded landscape. Called Uluru, or Ayer's Rock, this giant is a monolith 348 meters (1,142 feet) high, 3.6 kilometers (2.2 miles) long, and 9.4 kilometers (5.8 miles) around. It is the largest single rock known in the world. Tourists come from all over the country and the world to watch sunrise and sunset bring the colors of the rock to life. Some also make the challenging...

A crisp, clear winter day over France provided the International Space Station a detailed view of the city of Paris. This image, rotated and cropped from the original, shows the recognizable street pattern of the city--and some of the world's most notable landmarks--along the Seine River. One of the main avenues radiating like spokes from the Arc de Triomphe (image upper left) is the Avenue des Champs-Élysees running southeast to the Garden of Tuileries (Jardin des Tuileries). The...

Like streamers of splattered paint, the tracks of nearly 150 years of tropical cyclones weave across the globe in this map. The map is based on all storm tracks available from the National Hurricane Center and the Joint Typhoon Warning Center through September 2006. The accumulation of tracks reveals several details of hurricane climatology, such as where the most severe storms form and the large-scale atmospheric patterns that influence the track of hurricanes. Over time, the repeated passage...

If you asked almost anyone to describe a tropical island, they would likely mention palm trees and flat, white sandy beaches that stretch for kilometers: they would describe a coral atoll. Coral atolls are normally long, thin bars of white sand that rise just a few meters above sea level. The island or island group surrounds a hollow center where a volcanic peak once was. The atoll shown in this photo-like satellite image is the island of Tureia, in French Polynesia, about 930 kilometers...

For centuries, mariners had to travel an extra 340 kilometers (185 nautical miles) between the Gulf of Corinth and the Saronic Gulf. The reason for this extra distance was a thin strip of land only about 6 kilometers (4 miles) across. The Isthmus of Corinth connects mainland Greece in the north to the Peloponnese Peninsula in the south. In the late 19th century, ships' journeys shortened with the completion of the Corinth Canal.

What atmospheric scientists refer to as open cell cloud formation is a regular occurrence on the back side of a low-pressure system or cyclone in the mid-latitudes. In the Northern Hemisphere, a low-pressure system will draw in surrounding air and spin it counterclockwise. That means that on the back side of the low-pressure center, cold air will be drawn in from the north, and on the front side, warm air will be drawn up from latitudes closer to the equator. This movement of an air mass is...

GRACE is the newest tool for scientists working to unlock secrets of ocean circulation and its effects on climate. Created from 111 days of selected GRACE data to help calibrate and validate the mission's instruments, this preliminary model improves knowledge of the gravity field so much it is being released to...

The mega-iceberg A53a (upper image) measured close to 50 kilometers by 22 kilometers, about seven times the area of Manhattan Island, in mid-January 2008 when astronauts took the photographs for this mosaic. The images were acquired from the International Space Station (ISS), located 780 kilometers to the north of the iceberg at an altitude of 341 kilometers; the perspective distorts the oblong shape of the iceberg, making it look squarer than it actually is. At the time the photographs were...

Abutting the southern front of the snow-clad Himalaya Mountains, the broad, flat Ganges Plain is laced with rivers that transport glacial melt to the Bay of Bengal or the Arabian Sea. Not surprisingly, these rivers lead something of a Dr. Jekyll-Mr. Hyde existence: during the dry winter, the rivers are small and sedate, their headwaters largely locked in ice. In the summer, temperatures in the mountains climb, melting mountain-top snow and fueling the Asian monsoon, and the rivers swell into...
