Great work!

May I suggest you to try to increase the brilliance off the planet. I
think that the dark side should be black. (It's only my opinion-)

Progressing well.  It's as if the clouds (and planet?) are being lit by a
another light, so maybe it's the diffuse from that.  The 3D of the clouds
looks nice.  Maybe Alberto meant 'diffuse' brightness and not 'brilliance' but
that could help too by decreasing the lightness at the terminator while
getting a lighter sun-facing side.  Not sure this would be of help but if you
use larger than rgb 1 color values for the clouds and drop the 'ambient' to
zero (or nearly so) it might do better for the shadow side, and lit side too
for that matter.

ambient is zero.  the one light source is a circular 3by3 area light
with orient on. there is no light behind the planet.  radiosity was on. 
nearly all of the pictures i've seen lately of our planet show faint
details on the dark side just like the small pic from first contact.  i
assume it's light bouncing around the atmosphere.  i also have my light
set to rgb<1,1,1>*2.  *3 was too bright, so i might have to go in
between.  i may try to increase the cloud color above one.  that seems
like a good idea, thanks.

Does it have any effect? I mean, space is empty so there aren't
anyhing to reflect light.

K.K.

It should actually create a darkening effect from the blackness of the
background.  Might depend on the radiosity used perhaps, if official or
unofficial, but I think it applies the surroundings similarly in either.

  Um, if you're basing this on real life, don't forget that the moon is a 
very big secondary source of light.  Plenty of light to illuminate clouds, 
maybe enough to show a reflection of the moon in the ocean if nothing else 
in the shot washes it out.  The CGI movie shots you mention probably took 
that into account.
