Gemasolar Thermosolar Plant in Seville, Spain. The solar concentrator contains 2,650 mirrors that focus the sun’s thermal energy to heat molten salt flowing through a 140-metre-tall (460-foot) central tower. The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity.

Hagadera, seen here on the right, is the largest section of the Dadaab refugee camp in northern Kenya and is home to 100,000 refugees. To cope with the growing number of displaced Somalis arriving at Dadaab, the UN has begun moving people into a new area called the LFO extension, seen on the left. Dadaab is the largest refugee camp in the world with an estimated total population of 400,000.

Hạ Long Bay, located in the Quảng Ninh Province of Vietnam, is a stunningly beautiful destination. Here, towering limestone pillars and tiny islands topped by a rich, green forest rise from the beautiful waters of the Gulf of Tonkin.

Tailings are the waste and by-products generated by mining operations. The tailings seen here were pumped into the Gribbens Basin, fron iron ore mines in Michigan, USA. Once the materials are pumped into the pond, they’re mixed with water to create a sloppy form of mud known as slurry. For a sense of scale, this Overview shows approximately 2.5 square kilometres (1 square mile) of the basin.

Goodland, Kansas, USA. The circles seen here are created when lines of sprinklers, powered by electric motors, rotate 360 degrees to evenly irrigate crops.

Rice paddies, constructed in steps, cover the mountainsides of Yuanyang County, China. Cultivated by the Hani people for the last 1300 years, the slope of the terraces varies from 15 to 75 degrees with some having as many as 3,000 steps.

Angkor Wat, a temple complex in Cambodia, is the largest religious monument in the world (first it was Hindu, then Buddhist). Constructed in the twelfth century, the 820,000 square meter (8.8 million square feet) site features a moat and forest that surround a massive temple at its center.

Nishinoshima is a volcanic island located 940 kilometers (584 miles) south of Tokyo, Japan. Starting in November 2013, the volcano began to erupt and continued to do so until August 2015. Over the course of the eruption, the area of the island grew in size from 0.06 square kilometers (0.02 square miles) to 2·3 square kilometers (0·89 square miles).

The coal terminal at the Port of Qinhuangdao in China is the largest coal shipping facility in the country. From here, approximately 210 million tons of coal are transported to coal-burning power plants throughout southern China every year.

Dendritic drainage systems are seen around the Shadegan Lagoon by Musa Bay in Iran. The word ‘dendritic’ refers to the pools’ resemblance to the branches of a tree, and this pattern develops when streams move across relatively flat and uniform rocks, or over a surface that resists erosion.

The villas of marabe-al-dhafra in abu-dhabi-United Arab Emirates-are home to approximately 2000 people.

The Arlit uranium mine is located in Arlit, Niger. French nuclear power generation, as well as the French nuclear weapons program, are both dependent on the uranium that is extracted from this mine in the former French colony – more than 3,400 tons per year.

Mount Fuji is an active volcano and the tallest peak in Japan, rising 3,776 meters (12,389 feet). As seen in this Overview, Fuji has an extremely symmetrical cone, which is snow capped several months of the year.

Bourtange is a village with a population of 430 in the municipality of Vlagtwedde in the Netherlands. The star fort was built in 1593 during the Eighty Years’ War when William I of Orange wanted to control the only road between Germany and the city of Groningen. Bourtange was restored to its mid-18th-century state in 1960 and is currently used as an open-air museum.

Sossusvlei is a salt and clay pan located on the edge of the Namib Desert in Namibia. These reddish sand dunes of the desert, seen in the top half of this Overview, are among the tallest in the world, with many rising more than 656 feet (200 meters.)

Glacial melting and flooding occurs every year by the Skafta River in Iceland. As the water travels down towards the North Atlantic Ocean, incredible patterns are created on the hillsides. Rising lava, steam vents, or newly opened hot springs can all cause this rapid ice melt, leading to a sizable release of water that picks up sediment as it flows down from the glaciers.

Plasticulture refers to the practice of using plastic materials in agricultural applications. This is visible in the plains and valleys of Almeria, Spain where nearly 20,000 hectares (about 50,000 acres) are covered by these greenhouse structures.

Los Caracoles Pass, or The Snails Pass, is a twisting mountain road located in a remote section of the Andes Mountains on the Chilean side of the border with Argentina. The path climbs to an elevation of 10,419 feet, has no roadside safety barriers, and is frequented by large trucks.

Evaporation ponds are visible at the potash mine in Moab, Utah, USA

The salt evaporation ponds seen here cover roughly 10 square miles (26 square km) in San Francisco Bay, California, USA. Salt is extracted from the water here through a lengthy process. First, water from the bay is channeled into massive basins where it begins a transformation into brines. Over five years, the brines evaporate, concentrate, and travel several miles before they are collected as pure salt crystals. The massive ponds get their vibrant color from a particular species of algae (Dunaliella) that thrives in extremely salty water and produces a red pigment.

Burning Man is a week-long, annual event held in the Black Rock Desert of Nevada, USA. Each year a community of more than 65,000 participants is erected from nothing with one guiding principle being “leave no trace” as it ends. The event is described as an experiment in community, art, self-expression, and radical self-reliance. This image was taken during the event, in August 2014.

True to its purpose, the big NASA spacecraft that began orbiting Mars a decade ago has delivered huge advances in knowledge about the Red Planet. NASA’s Mars Reconnaissance Orbiter (MRO) has revealed in unprecedented detail a planet that held diverse wet environments billions of years ago and remains dynamic today.

The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter often takes images of Martian sand dunes to study the mobile soils. These images provide information about erosion and movement of surface material, about wind and weather patterns, even about the soil grains and grain sizes.

This image of Solis Planum — a huge mound south of the Mars canyon system Valles Marineris – was acquired by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter on Aug. 16, 2015, at 2:47 p.m. local Mars time.
