The Pacific Ocean teems with phytoplankton along the West Coast of the United States, as captured by the MODIS instrument on NASA’s Aqua satellite. Satellites can track phytoplankton blooms, which occur when these plant-like organisms receive optimal amounts of sunlight and nutrients. Phytoplankton play an important role in removing atmospheric carbon dioxide.

NASA is tracking lava flows from Hawaii Island’s Kilauea volcano as fissures erupt and lava makes its way to the ocean.
At 10:41 a.m. local time (20:41 Universal Time) on May 14, 2018, the Operational Land Imager (OLI) on Landsat 8 acquired a natural-color image of the volcano.

This image of the southern Greenland town of Narsaq was taken during an Operation IceBridge flight on Apr. 26, 2018. Operation IceBridge, NASA's longest-running airborne mission to monitor polar ice change, concluded this year's springtime survey of Arctic sea and land ice on May 2. The flights, which began on March 22, covered the western basin of the Arctic Ocean and Greenlands fastest-changing glaciers.

The eruption of Kilauea Volcano on the island of Hawaii triggered a number of gas- and lava-oozing fissures in the East Riff Zone of the volcano. The fissures and high levels of sulfur dioxide gas prompted evacuations in the area.
This ASTER image acquired May 6 picks up hotspots on the thermal infrared bands – shown in yellow. These hotspots are newly formed fissures and lava flows.

NASA astronaut Ricky Arnold captured this clear view of Mount Rainier National Park as the International Space Station orbited above at about 17,500 miles per hour. Arnold shared the image and a quote on April 25, to celebrate National Park Week: "'Doubly happy, however, is the man to whom lofty mountain tops are within reach, for the lights that shine there illumine all that lies below.' - John Muir on Mount Rainier."
