The Ganges River forms an extensive delta where it empties into the Bay of Bengal. The delta is largely covered with a swamp forest known as the Sunderbans, which is home to the Royal Bengal Tiger.

A marsh-like area borders the Demini River in northwestern Brazil. The Demini eventually joins the Amazon River.

Eastern Asia is dominated geographically by China, which stretches from the Tian Shan Mountains in the west to the sheltered bays of the Yellow Sea in the east.

Mexico and Central America together form the southern half of the North American continent. From the rugged deserts of the Baja Peninsula to the steamy rain forests of Panama, the region is a land of great contrasts.

Europe is a modestly sized continent, only Australia is smaller, but its long, irregular coastline is riddled with bays, inlets, islands, and peninsulas, both great and small.

South America stretches more than 7,500 kilometers from the warm Caribbean Sea almost to Antarctica. Waters from the eastern slopes of the Andes Mountains drain into mighty rivers, such as the Amazon, that traverse rain forests, grassy plains, and dry plateaus to eventually reach the Atlantic Ocean.

An intricate maze of small lakes and waterways define the Yukon Delta at the confluence of Alaska's Yukon and Kuskokwim Rivers with the frigid Bering Sea. Wildlife abounds on the delta and offshore where sheets of sea ice form during the coldest months of the year.

Resembling splotches of yellow and green paint, salt-encrusted seasonal lakes dot the floor of Western Australia's Shoemaker impact structure. The structure was formed about 1.7 billion years ago and is currently the oldest known impact site in Australia.

Between the fertile Euphrates River valley and the cultivated lands of the eastern Mediterranean coast, the Syrian Desert covers parts of modern Syria, Jordan, Saudi Arabia, and Iraq.

On the border between Chile and the Catamarca province of Argentina lies a vast field of currently dormant volcanoes. Over time, these volcanoes have laid down a crust of magma roughly 2 miles (3.2 km) thick. It is tinged with a patina of various colors that can indicate both the age and mineral content of the original lava flows.

Soaring, snow-capped peaks and ridges of the eastern Himalaya Mountains create an irregular white-on-red patchwork between major rivers in southwestern China. The Himalayas are made up of three parallel mountain ranges that together extend more than 2,900 kilometers.

Western Asia, the world's largest continent, occupies one-third of the Earth's landmass. Although divisions are somewhat arbitrary, Western Asia encompasses the Middle East and countries that surround the Caspian Sea, including Kazakhstan and Russia.

The Mediterranean Sea physically separates--but in other ways unites--southern Europe, the Middle East, and northern Africa.

The third largest continent, North America is a land of many facets: frozen tundra, rugged mountains, high plains, deserts, and lowland forests.

The first National Land Cover Dataset (NLCD), based on Landsat 5 data, is completed and available for distribution in 2000.

Sometimes described as resembling a stingray or a tadpole, the Batagaika Crater is a widening chasm in Siberia and the world’s largest permafrost crater.

The Landsat Global Archive Consolidation initiative has retrieved and ingested its 5 millionth image since it began in 2010. The data came from the Riyadh Ground Station in Saudi Arabia and was acquired by Landsat 5 on April 16, 1989. It shows an area over Bahrain, Qatar, and Saudi Arabia.

A Landsat 5 image of the Chernobyl Nuclear Power Plant site in Ukraine on April 29, 1986, three days after the accident, shows no warmth in the cooling pond.
