That is indeed a POV-Ray sphere wrapped in several rather large (as big as
4000x8000) Mercator projection black-and-white and color images of the
Earth, which are available at the NASA website. All in all I use four
different mercator images to make the Earth: one is an exaggerated relief
black-and-white image that I use as a bump map for the landmasses, another
is a two-color black and white image that is used as a landmass mask for the
specularity texture map on the oceans and lakes, yet another is a image
that's nothing but the cloud layer, and finally there is a large true-color
image of the land, water and icepacks.
