For what it's worth this drove me crazy when I worked on the "Reach for the 
stars" image. It's even mentioned in the "Making of". See the artifact under 
the kid's left eye: http://www.oyonale.com/iss/english/makingof_3.htm

I never found a solution, that's why the kid isn't facing the viewer in the 
final image... It's definitely related to a mixture of transparent and 
non-transparent zones in certain meshes, under certain lighting conditions.
