NASA's Visible Earth

A searchable directory of images, visualizations, and animations of the Earth. The purpose of NASA's Visible Earth is to provide a consistently updated, central point of access to the superset of NASA's Earth science-related images, animations, and data visualizations. These images are considered to be public domain and, as such, are freely available to the interested public-at-large, the media, scientists, and educators for re-use and/or re-publication.
