NASA.gov brings you images, videos and interactive features from the unique perspective of America’s space agency.

NASA has stunning galleries of images, including this link to images of the day.  NASA has also recently made the 172-page e-book Earth as Art a free download (PDF). 

About the Image: Portrait of Global Aerosols

“High-resolution global atmospheric modeling run on the Discover supercomputer at the NASA Center for Climate Simulation at Goddard Space Flight Center, Greenbelt, Md., provides a unique tool to study the role of weather in Earth’s climate system. The Goddard Earth Observing System Model, Version 5 (GEOS-5) is capable of simulating worldwide weather at resolutions of 10 to 3.5 kilometers (km).  This portrait of global aerosols was produced by a GEOS-5 simulation at a 10-kilometer resolution. Dust (red) is lifted from the surface, sea salt (blue) swirls inside cyclones, smoke (green) rises from fires, and sulfate particles (white) stream from volcanoes and fossil fuel emissions.”
