The mountain range running diagonally through the right side of this orthorectified image can be divided into two parts: the Olaroz Grande (above) and Olaroz Chico (below). The range is located in the Susques Department of Argentina’s Jujuy Province, just east of the Chilean border.

Olaroz Grande reaches heights of over 4800 meters, while the aptly named Olaroz Chico is lower at between 4200 and 4400 meters. Located near the mountains is the similarly named Salar de Olaroz, a salt flat.

Lake Constance (in German, Bodensee) is a lake on the Rhine at the northern foot of the Alps. It consists of three bodies of water: the Obersee (“upper lake”), the Untersee (“lower lake”), and a connecting stretch of the Rhine, called the Seerhein.

The lake is situated in Germany, Switzerland and Austria near the Alps. Specifically, its shorelines lie in the German states of Bavaria and Baden-Württemberg, the Austrian state of Vorarlberg, and the Swiss cantons of Thurgau and St. Gallen. The Rhine flows into it from the south.

The freshwater lake sits at 395 m above sea level and is Central Europe’s third largest, after Lake Balaton and Lake Geneva. It is 63 km long, and at its widest point, nearly 14 km. It covers approximately 571 km² (208 mi²) of total area. The greatest depth is 252 m in the middle of the eastern part (Obersee). Its volume is approximately 55 km³.

The Japanese islands of Honshū, the country’s largest isle, and Shikoku, across the Seto Inland Sea, are visible here despite some cloud cover.

Honshū is roughly 1,300 km long and ranges from 50 to 230 km wide, with a total area of 227,962.59 km² (60% of the total area of Japan). Its area has been expanding with land reclamation and coastal uplift in the north, but global sea level rise has diminished these effects.

Honshū has 5,450 km of coastline. Here, cities such as Osaka, Nagoya and Tokyo can be seen hugging the shores of bays indented into the island’s southern coast. Inland, a mountain range runs along the length of Honshū from end to end.

Shikoku, on the contrary, is the smallest and least populous of the four main islands of Japan. It has a length of 225 km and a width ranging from 50 to 150 km across.

Lake Hulun, also known as Dalai nuur, is located in Inner Mongolia, China, just south of the border with Russia and east of the border with Mongolia. It is one of the five largest freshwater lakes in all of China, covering approximately 2,339 km².

Flowing across the high steppes of Mongolia into China and Lake Hulun is the Kherlen or Kerülen River, which has a total length of 1,254 km. Located nearby, to the southeast of Lake Hulun, is the smaller Lake Buir. The lake is on the China-Mongolia border and surrounded by the Hulun Buir grasslands.

The cities of Boston, Massachusetts (above) and Providence, Rhode Island (below) appear as grey areas amidst the generally green terrain of this part of the northeastern United States of America.

Protruding out into the Atlantic Ocean is the Cape Cod peninsula, part of Massachusetts. Below it are the islands of Martha’s Vineyard (left) and Nantucket (right), also belonging to that state.

Some phytoplankton can be seen in Nantucket Sound, between the peninsula and the islands. Upon opening the full image, the green phytoplankton can be seen reaching much farther out to the east, into the Atlantic.
