On Aug. 25, 2015, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Aqua satellite captured a visible picture of Typhoon Goni after it moved out of the East China Sea and north into the Sea of Japan. The MODIS image also showed that the storm’s western quadrant was over North Korea and South Korea, while the eastern quadrant stretched over most of the big island of Japan.

New research using NASA satellite data and ocean biology models suggests tiny organisms in vast stretches of the Southern Ocean play a significant role in generating brighter clouds overhead. Brighter clouds reflect more sunlight back into space, affecting the amount of solar energy that reaches Earth’s surface, which in turn has implications for global climate.

This “Blue Marble” image is the first fully illuminated snapshot of Earth captured by the DSCOVR satellite, which will capture and transmit full images of Earth every few hours. The information will help examine a range of Earth properties, such as ozone and aerosol levels, cloud coverage, and vegetation density, supporting a number of climate-science applications.

Saturn’s moon Titan is home to seas and lakes filled with liquid hydrocarbons, but what forms the depressions on the surface? A new study using data from the joint NASA and European Space Agency (ESA) Cassini mission suggests the moon’s surface dissolves in a process similar to the creation of sinkholes on Earth. Apart from

This interferogram was created by combining two Sentinel-1A radar scenes from March 2 and March 14, 2015, over the Danube Delta in Romania, which covers more than 4,000 square kilometers and plays important roles in water supply and biodiversity.

NASA satellite imagery shows that for much of March 2015, the Ohio River watershed was above flood stage, particularly just above the confluence with the Mississippi River. The cause was a combination of melting snow and heavy rainfall.
