Most summers, jewel-toned hues appear in the Black Sea, a result of phytoplankton that trace the flow of water currents and eddies. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite recently collected imagery of such an ongoing phytoplankton bloom.
The European Space Agency (ESA) Copernicus Sentinel-2A satellite collected an image of part of the Great Barrier Reef off Australia's northeast coast on April 1, 2017.
Grasslands cover approximately 37 percent of Earth's land surface when calculated with shrub-lands and savannas. In Western Europe, grasslands comprise 40 percent of agricultural land. And now European Space Agency (ESA) Copernicus Sentinel satellites are being used to detect and better evaluate management practices of grasslands in Estonia.
The European Space Agency (ESA) Sentinel-2A satellite collected this image over western India: a seasonal salt marsh known as the Rann of Kutch.
Fort Bourtange is a star-shaped moat fort, located in the village of Bourtange in the east of Groningen in the Netherlands near the German border. This fort was built in 1593 to create a border around the only road between Germany and Groningen, which was was occupied by Spaniards around the time of the Eighty Years War.
The European Space Agency (ESA) Copernicus Sentinel-3A satellite collected this image of the Bering Sea, north of the Alaska Peninsula, on March 26, 2017.
On Feb. 13, 2017, the combined Arctic and Antarctic sea-ice numbers were at their lowest point since satellites began to continuously measure sea ice in 1979.
The European Space Agency (ESA) Copernicus Sentinel-2A satellite captured this image of the Vojvodina region of northern Serbia. The area lies in the southern part of a region previously covered by the Pannonian Sea from two million to 23 million years ago. Today, the land boasts a fertile soil, as evidenced by the many agricultural fields visible as geometric shapes.
Utah's Bryce Canyon is not the deepest canyon in the United States; its largest amphitheater of naturally eroded rock drops 240 meters. Arizona's Grand Canyon, for comparison, measures more than 1,800 meters deep in places. But photographers who visit Bryce Canyon National Park typically aren't looking for dizzying heights and depth; they're often trying to capture images of the delicate spires called hoodoos that rise from the canyon.
Approximately 250 million measurements taken by the European Space Agency (ESA) CryoSat during the last six years have been used to create a unique 3D view of Antarctica, offering a snapshot of the undulating surface of this vast ice sheet.
