TheEarth

This object comprises a simple scene file and a choice of 3 copyright free images of the earth from http://www.evl.uic.edu/pape/data/Earth/. The scene file maps an image onto a sphere and optionally adds clouds. http://www.evl.uic.edu/pape/data/Earth/ also contains higher resolution images than those incorporated in this object and various other earth images derived from different data sources. All of the images there are in a cylindrical (latitude/longitude) projection, so are suitable for mapping to a sphere in the same way.
