Published Nov 27, 2008Located in the Bahia de los Angeles, Isla Coronado sits in the Gulf of California, just off the eastern shoreline of Mexico’s Baja Peninsula. The island is approximately 7 kilometers long, and it is dominated by Volcan Coronado on the northern end.
Published Oct 20, 2008Fraser Island, the world’s largest sand island, is located along the coastline of Queensland, Australia, and it includes Great Sandy National Park. The island was designated a World Heritage site in 1992, in part due to its outstanding preservation of geological processes related to sand dune formation.
Published Oct 13, 2008Bouvet Island is known as the most remote island in the world; Antarctica, over 1600 kilometers (994 miles) to the south, is the nearest land mass. Located near the junction between the South American, African, and Antarctic tectonic plates, the island is mostly formed from a shield volcano—a broad, gently sloping cone formed by thin, fluid lavas—that is almost entirely covered by glaciers.
Published Oct 6, 2008The urban area of Tunis is located on a flat coastal plain, and is distinguished in this astronaut photograph from the surrounding desert by the pattern of grey and tan buildings and the dark street grid. The city is bordered by an evaporating saline lake to the northeast known as Sebkhet Arina (upper left).
Published Sep 22, 2008he island of Ischia is approximately 30 kilometers southwest of Naples, Italy, in the western Bay of Naples (part of the Tyrrenhian Sea). While the island’s rocks are volcanic in origin, much of the island’s geology and current topography is characterized by blocks of uplifted rock and sunken areas between weak spots or cracks in Earth’s crust.
Published Sep 15, 2008The setting sun glints off the Amazon River and numerous lakes in its floodplain in this astronaut photograph from August 19, 2008. Large areas of sunglint are common in oblique views. Sunglint images reveal great detail in surface water—in this case the marked difference between the smooth outline of the Amazon and the jagged shoreline of the Uatumã River.
Published Sep 8, 2008The Aeolian Islands formed from a chain of volcanoes in the Tyrrhenian Sea north of the island of Sicily. Geologists and volcanologists have studied the islands since the eighteenth century, and the United Nations Educational, Scientific, and Cultural Organization (UNESCO) declared them a World Heritage Site in 2000 because of their value to the study of volcanic processes.
Published Sep 1, 2008The image is highly oblique—taken from an angle looking outwards from the ISS, rather than straight down towards the Earth—and this perspective provides a sense of topography along the southern edge of Greenland. The exposed dark grey bedrock along the southwestern coastline has been carved by glaciers into numerous fjords, steep-sided valleys that drain directly into the ocean.
Published Aug 25, 2008The Dry Tortugas are a group of islands located approximately 75 miles west of Key West, Florida; they form the western end of the Florida Keys in the Gulf of Mexico. This astronaut photograph highlights three islands in the group: Bush Key, Hospital Key, and Garden Key, which is the site of Fort Jefferson, a Civil War-era fort.
Published Aug 18, 2008While the pyramids of Giza are perhaps the most famous, there are several other ancient Egyptian royal necropolis (“city of the dead”) sites situated along the Nile River and its delta. One of these sites is near the village of Dashur, illustrated in this astronaut photograph.
Published Aug 11, 2008Polar mesospheric clouds (also known as noctilucent, or “night-shining” clouds) are transient, upper atmospheric phenomena that are usually observed in the summer months at high latitudes (greater than 50 degrees) of both the Northern and Southern Hemispheres. They appear bright and cloudlike while in deep twilight. They are illuminated by sunlight when the lower layers of the atmosphere are in the darkness of Earth’s shadow.
