These are beautiful images taken by the Landsat-7 satellite - and most recently, the Terra Satellite's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER).
The top one is the Ganges River Delta in India, where the Bengal Tiger roams.
The orange & blue one is the Malaspina Glacier in Alaska.
The blue & green one is the Mississippi River Delta.
Pretty amazing stuff, huh! I just love the colors!
