Fraser 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.

Bouvet 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.

he 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.

The 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.

The 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.

The 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.

Polar 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.

In the late 1990s, Egypt’s new manmade Toshka Lakes, fed from Lake Nasser via a canal, grew and spilled into new basins to become four major and two smaller lakes. Starting in 2002, astronauts have seen the lakes slowly decline, with the telltale ring of darker, moistened ground showing the previous higher water levels.

This astronaut photograph illustrates the diverse built environment surrounding the NASA Ames Research Center located at the southernmost end of San Francisco Bay. Founded in 1939 as an aircraft research laboratory, Ames became a NASA facility in 1958. Its original aircraft research focus was enhanced by the adjacent Moffett Field—an active Naval Air Station until 1994, and the original home of the Navy dirigible U.S.S. Macon. The large hanger for docking the U.S.S. Macon is still present at Moffett Field, and is visible in this astronaut photograph (image center). Today, NASA Ames includes the former Naval Air Station, and it continues its focus on aeronautics in addition to nanotechnology, information technology, fundamental space biology, biotechnology, thermal protection systems, and human factors research.
