The Landsat satellites have been gathering data about Earth for 40 years - the first one was launched in 1972. The images in this gallery have been coloured with a digital palette by the US Geological Survey to highlight certain features.
Siberian Ribbons - June 15th, 2005 - Vivid colors and bizarre shapes come together in an image that could be an abstract work of art or an illustration for a fantasy story. This labyrinth of exotic features is present along the edge of Russia’s Chaunskaya Bay (vivid blue half circle) in northeastern Siberia. Two major rivers, the Chaun and Palyavaam, flow into the bay, which in turn opens into the Arctic Ocean. Ribbon lakes and bogs are present throughout the area, created by depressions left by receding glaciers.
