Latest render. Made using High res maps from NASA. The clouds are volumetric using a sphere with a solidify modifier (applied) then micro displacement with Blender’s experimental setting. I may touch them up in the future.

This one was made previous to the top. The clouds are similar but I used a diffuse on top of the volumetric nodes. The atmosphere more basic volumetric.

My first earth render. the clouds are just an image on the sphere using a diffuse node. Not volumetric.
