Earth As Art
NASA has released a book called "Earth as Art," showing 75 stunning satellite images of formations around our planet.
The images appear in colors that clearly could not be natural to you. NASA explains that the satellite's sensors can measure light outside of the visible range, so the images are not necessarily ones visible to the naked eye.
We've posted all the images here, but you can buy it from the U.S. Government Printing Office online at: http://bookstore.gpo.gov
