From A DISTANCE



Creating a striking design which looks a bit like a serpent swimming through clouds, curling patterns of eddies are formed as air flows around and over the island of Tristan de Cunha in the South Atlantic. These spiraling cloud patterns, caused when prevailing ocean winds encounter an island, are known as von Karman vortices or 'vortex streets'. Home to about 275 people, Tristan de Cunha is considered to be the most remote inhabited island in the world, lying 2,816km (1,750 miles) from South Africa, the nearest land, and 3,360km from South America

Cloudless skies allow a clear view of dust and hydrogen sulfide plumes along the coast of Namibia. Multiple dust plumes blow off the coast toward the ocean, most or all of them probably arising from streambeds

Aqua satellite detected 148,946 fires in this image on August 23, 2010. The fires are outlined in red. Most of the fires are concentrated in Bolivia, where the governments of two states had declared a state of emergency because of widespread fires three days earlier. Scores of fires also burn in Brazil, Paraguay, and Argentina. While some fires do occur naturally in Bolivia, most of these fires were probably set deliberately to clear land for crops or pasture.

Clear skies in late June 2010 allow sunlight to melt snow and ice in the Arctic. The conditions mean unfiltered sunlight can reach the Arctic’s land and sea surfaces at a time of near round-the-clock daylight

Cape Kazantip is a prominent headland on the Kerch Peninsula, which defines the southern shore of the Sea of Azov and the east extension of the Crimean Peninsula. It has been the warm holidaying destination for generations of Ukrainians and Russians. Green and brown fields show intensive agricultural activity in the area, and salt ponds are visible at the west end of the shallow Lake Aktashskoye at the centre of the image.

Hurricane Danielle churns in the Atlantic Ocean on 23 August, 2010. Winds reached speeds of 100mph (160kph)

At the western end of the Samoan Island chain lies Savai'i. Stretching more than 649sq miles, Savai'i is one of the largest landmasses in Polynesia. The mountainous island is a shield volcano that reaches its highest altitude 6,095 feet near the center of the island. The region's tropical, humid climate sustains vegetation that carpets much of the island
