Satellite images give scientists a better understanding of Earth's climate and geology,
but the pictures are also often beautiful in their own right. This picture of cloud
formations over the western Aleutian Islands is part of an "Earth as Art" collection
from the Landsat 7 satellite. The color variations are probably due to differences in
temperature as well as in the size of the water droplets that make up the clouds. (USGS/NASA)
