A few NASA Earth Observatory images from the past few months:
Mataiva Atoll, Tuamotu Archipelago, South Pacific Ocean, August 30, 2010

This image makes a great desktop background. The full-resolution image doesn’t have labels.
The Water Planet, October 2, 2010

Arthur C. Clarke once remarked, “How inappropriate to call this planet Earth when it is quite clearly Ocean.”
Susitna Glacier, Alaska, October 20, 2010

Note the complex ice deformation along much of the length of glacier. Most of the lower portion of the glacier is completely covered by debris.
Strong Extratropical Cyclone Over the US Midwest, October 29, 2010

This low pressure system brought severe weather to much of the central U.S., and set a record low atmospheric pressure for a non-hurricane storm in the U.S.
Matusevich Glacier, Antarctica, November 7, 2010
