NASA has made public some truly splendid hi-res snaps of planet Earth - lovingly cobbled together from a "a collection of satellite-based observations":
Impressive stuff. Here's the accompanying blurb:
This spectacular "blue marble" image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualisers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometre (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across.
