Yes, it could, but I wanted to stay as realistic as possible. The thin layer 
of atmosphere should be visible only at close range (see attached photo).

Can you publish here a smaple of scattering media? It would help me a lot! I 
try it now with a sphere and a pigment_map, but have first to figure out how 
to create a spherical pigment_map, as gradients x, y or z are only towards 
one axis. I hardly worked before with pigment_maps.

Hmm, here you might have a point, but not for sure. So far as I know, you 
might not see individual lights (of course not), but just the biggest 
clusters of lights such created by big cities and maybe reflecting clouds 
above them. But I am not sure. But in any way, lights look good. If only I 
could find a way to manage that they would be only at the nightside of 
earth...

That would help me also for future planet renders...

Greetings,

Sven
