Environmental Graffiti recently posted some spectacular image of Earth, taken by NASA’s satellites, and exhibited in 2000 at the Library of Congress. This one of the Malaspina Glacier in Alaska is my favorite:

You can see the Library’s Earth as Art exhibit online.

Also check out Environmental Graffiti for other great pictures of this planet (for example, another of my favorites: the 10 Creepiest Trees on Earth).

Enjoy (:
