Small glaciers spill into a mostly dry valley in western Greenland in this picture from August 29, 2009. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired this natural-color image. The top view shows the wider area and the bottom view is a close-up of two glacier snouts.

Solar evaporation (salt) ponds near the foot of a long alluvial fan in the Pampa del Tamarugal, the great hyper-arid inner valley of Chile’s Atacama Desert. Alluvial fan sediments are dark brown. Astronaut photograph ISS019-E-14473, May 5, 2009 with a Nikon D2X digital camera fitted with a 400 mm lens, by the ISS Crew.


Millennium Island (Caroline Island prior to 2000) at the southern end of the Line Islands in the South Pacific, Republic of Kiribati. 32 atolls and 1 raised coral island. Millennium Island is formed from a number of smaller islets built on coral reefs. Max 6 m above sea level.


The Moon’s shadow engulfed Taiwan and a large swath of southeastern China and the Pacific Ocean on the morning of July 22, 2009, during an unusually long total eclipse of the Sun. This pair of images from the Japanese geostationary satellite MTSAT show the view of Earth at 8:30 a.m. local time in Taiwan (left) and an hour later (right), near the time in eastern China when the disk of the Moon completely overlapped the disk of the Sun (called totality). The longest period of totality occurred over the Pacific, where the total eclipse lasted more than 6 minutes.
