Satellite image of clouds forming Karman vortices, an effect that occurs when an object disturbs the flow of a fluid, leading to the creation of a chain of spiral eddies over the islands of Broutona, Chirpoy, and Brat Chirpoyev, all part of the Kuril Island chain found between Russia's Kamchatka Peninsula and Japan. Image was taken using infrared, near-infrared and visible wavelengths of light. Photographed by the Enhanced Thematic Mapper Plus sensor on the joint NASA/US Geological Survey satellite, Landsat 7.
