High above the earth hover satellites; their eyes trained on the surface, capturing images from a perspective few humans will ever experience.
Besides their unique position, these satellites are capable of discerning details the human eye misses. The intense detail captured by the Landsat-7 satellite—and the thermal gradients illustrated by NASA's Terra Satellite's Advanced Spaceborne Thermal Emission and Reflection Radiometer—show earth for what it is: A fragile work of art.
