Most of this image is in the Simpson Desert Regional Reserve of South Australia. The shallow lakes, appearing in colors ranging from nearly black to aqua blue, are dry most of the time. Here, they seem to stretch with the sand dunes, which extend for hundreds of kilometers.

Variously shaped fields of crops decorate the rich Canterbury Plains on New Zealand's South Island. This 2015 Landsat image shows the farmland abutting the  Waimakariri River that winds down toward the city of Christchurch and ultimately the Pacific Ocean.

The total area (land and water) of Rhode Island is only 1,545 square miles. The state measures about 37 miles east-west, and about 48 miles north-south.

The Salar de Atacama in Chile is a large, dry salt flat surrounded by mountain ranges and is one of the driest places on Earth. Parts of the Atacama Desert have gone without rain for as long as people have been keeping track, but water rich in dissolved salts lies beneath this flat surface. The Salar is particularly rich in lithium salts.

Earth Science reminds us that the study of Earth and its biological processes can occur anywhere—whether we realize it or not.

High Resolution Orthoimagery archived at the USGS EROS Center and inset into the larger image show the New Jersey coastal town of Mantoloking five years before Sandy made landfall, as well as the slow recovery three years after the storm.

The Haruj Volcanic Field in central Libya was created from basaltic lava flows that erupted over time from multiple volcanoes. The volcanic craters and lava flows are evidence of a previous active eruption period. Many of the bright spots within the darker colored basalt flows are depressions covered with silt and fine sand.

The biologically complex conditions of mangroves are shown in dark green along the fingers of the Ord River in Australia. Yellow, orange, and blue represent the impressive flow patterns of sediment and nutrients in this tropical estuary. The bright spot at the lower left is an area of mudflats, which is home to saltwater crocodiles.

Like scratches on a marble table, airplane contrails cut across the southern California Mojave Desert. The shadows from the contrails cast dark lines across the ground. Contrails form when cold, dry air mixes with warmer aircraft exhaust.

The Green River and the Colorado River meet within Canyonlands National Park in Utah. Snow-covered Mount Waas, shown in light blue on the right side of the image, overlooks the arches, canyons, and bizarre rock formations that prevail throughout this region.

Lake Manicouagan, Canada, is one of the Earth's largest and oldest known impact craters. The crater is 65 kilometers (40 miles) wide and is estimated to be about 214 million years old. The lake and island are clearly seen from space and are sometimes called the "Eye of Quebec."

A mesmerizing plume creates a paradox of light and dark, brilliant and murky. The dark water of the Suwannee River flows from the Okefenokee Swamp in southern Georgia to the Gulf of America in Florida. The river’s inky color comes from decaying vegetation at the river’s swampy source.

The tendency to recognize human faces in things that are not human is common. Can you see the eye, nose, and mouth in this satellite image of Morocco? The face captured in this "Earth Selfie" appears to be quietly watching over the waters just off its coast. The city of Agadir is underneath the chin, and the irrigated farms of the Souss Valley appear in red.

A 2014 ASTER image of Baektu Mountain, an active volcano on the border between North Korea and China. The crater lake at the summit is called Heaven Lake. ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) is an instrument, resulting from a U.S. and Japanese partnership, that is aboard NASA's Terra satellite.

This ASTER image of the Sheveluch volcano covered in ash atop the snow cover of winter on Russia's Kamchatka peninsula was captured in 2014 after recent eruptions. ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) is an instrument, resulting from a U.S. and Japanese partnership, that is aboard NASA's Terra satellite.

Within the Hamersley Iron Province in Western Australia, Landsat's shortwave infrared and near-infrared detectors highlight different types of rock. The oval in the upper center part of the image is a geological feature called Rocklea Dome. The dark meanders within the dome are channel iron deposits.

This enhanced image of Western Australia resembles a mixture of crayons that melted in the sun. The yellow sand dunes of the Great Sandy Desert cover the upper right portion of the image. Red splotches indicate burned areas from grass and forest fires, and the colors in the rest of the image depict different types of surface geology.

The patterns and colors in the Zagros Mountains of Iran are interesting enough. For example, the infrared view provides a patina-like outline to the mountains. But something more happened to this unique landscape. Interrupting the mountain patterns are irregular dark patches called salt glaciers.

Slessor Glacier in Antarctica flows between the angular promontory Parry Point on the top left of the image and the Shackleton Range on the lower right. The purple highlights are exposed ice. Strong winds blow away the snow cover and expose lines that indicate the glacier flow direction. Rock outcrops next to the glacier also exhibit some of this bare ice.
