PIX4659322: St. Helene Island - St. Helena Island - St. Helene Island seen from the International Space Station (ISS) on 7 May 2009. Sainte-Helene is located 1860 km off the African coast in the Atlantic Ocean. Saint Helena Island, located in the South Atlantic Ocean approximately 1,860 kilometers (1,156 miles) west of Africa, was one of the many isolated islands that naturalist Charles Darwin visited during his scientific voyages in the nineteenth century. This image was acquired by astronauts onboard the International Space Station on May 7, 2009. This astronaut photograph shows the island's sharp peaks and deep ravines; the rugged topography results from erosion of the volcanic rocks that make up the island. The change in elevation from the coast to the interior creates a climate gradient. The higher, wetter center is covered with green vegetation, whereas the lower coastal areas are drier and hotter, with little vegetation cover. Human presence on the island has also caused dramatic changes to the original plants and animals of the island. Only about 10 percent of the forest cover observed by the first explorers now remains in a semi-natural state, concentrated in the interior highlands. Saint Helena Island is perhaps best known as the final resting place of Napoleon Bonaparte I of France. Bonaparte was exiled to the island following his defeat at the Battle of Waterloo in 1815; he died on the island six years later in 1821. Today, the island is a British Overseas Territory, with access provided thirty times a year by a single ship, the Royal Mail Ship St. Helena / Bridgeman Images
PIX4659396: Africa by satellite. Chad - Possible impact crateres - radar view - 20/03/1996 The impact of an asteroid or comet several hundred million years ago left scars in the landscape that are still visible in this spaceborne radar image of an area in the Sahara Desert of northern Chad. The concentric ring structure left of center is the Aorounga impact crater with a diameter of about 17 kilometers (10.5 miles). Scientists are using radar images to investigate the possibility that Aorounga formed as part of a multiple impact event. A proposed second crater, similar in size to the main structure, appears as a circular trough surrounding a central peak in the center of the image. A third structure, also about the same size, is seen as a dark, partial circular trough with a possible central structure in the right center of the image. The proposed crater “” chain”” could have formed when a 1 km to 2 km (0.5 mile to 1 mile) diameter object broke apart before impact. The dark streaks are deposits of windblown sand that migrate along valleys cut by thousands of years of wind erosion. Radar imaging is a valuable tool for the study of desert regions because the radar waves can penetrate thin layers of dry sand to reveal details of geologic structure that are invisible to other sensors. The image was acquired by the Spaceborne Imaging Radar - C/X - band Synthetic Aperture Radar (SIR - C/X - SAR) on April 18 and 19, 1994, onboard the space shuttle Endeavour. The area shown is 45 kilometers by 61 kilometers (28 miles by 38 miles) and is centered at 19.25 degrees north latitude, 19.25 degrees east longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations as follows: red is L - band, horizontally transmitted and received; green is C - band, horizontally transmitted and received; and blue is C - band, horizontally transmitted, vertically received.

PIX4659777: Bahrain viewed from space - Bahrain and parts of Saudi Arabia: The Kingdom of Bahrain and the East Coast of Saudi Arabia seen by Sentinel-2A satellite on 18 September 2015 - This beautiful, natural-colour image from Sentinel-2A on 18 September 2015 features the small nation of Bahrain and parts of eastern Saudi Arabia - Located on the southwestern coast of the Persian Gulf, Bahrain is a small Arab state, made up of an archipelago consisting of Bahrain Island and some 30 smaller islands - In the middle of the image, on the Persian Gulf, the King Fahd Causeway is clearly visible. Built between 1981 and 1986, it consists of a series of bridges and stretches of road connecting Saudi Arabia and Bahrain. The Saudi and Bahraini passport control centres are also noticeable in the middle of the Causeway - On the right of the image is the island of Bahrain, home to some 1.5 million people, with its modern capital Manama featured at the top. The greys represent the densely built city centre and surrounding towns - On the top right part of the island, on a smaller island about 7 km northeast of the capital, Bahrain International Airport is visible - Most of Bahrain is a flat and arid desert plain, with recurrent droughts and dust storms the main natural dangers for its inhabitants. Famous for its pearl fisheries for centuries, today it is also known for its financial, commercial and communications sectors - Towards the central left part of the island, Bahrain University is observable. Also visible, the Al Areen Wildlife Reservation, both a nature reserve and zoo, one of the five protected areas of the country, and the only protected area on land - On the bottom-right tip of the island a series of horseshoe-shaped artificial atolls are clearly visible. Durrat Al Bahrain, one of the largest artificial islands in Bahrain, comprises six atolls and five fish-shaped islands - On the left side of the image, in Saudi Arabia, part of the Rub 'al-Khali, the world's largest sand desert, / Bridgeman Images
