The next generation of The Blue Marble is out. If you don't know what that is, NASA has made extremely high resolution images of the earth available for download.
In celebration of the deployment of its Earth Observing System, NASA is pleased to share the newest in its series of stunning Earth images, affectionately named the “Blue Marble.” This new Earth imagery enhances the Blue Marble legacy by providing a detailed look at an entire year in the life of our planet. In sharing these Blue Marble images, NASA hopes the public will join with the agency in its continuing exploration of our world from the unique perspective of space.
The detail is exquisite, approximately 500 meters per pixel and many different file sizes are available for the entire series. (For those who are gluttons for punishment or have really high speed connections, the largest ones run up around 11-12 Gb).
