In a later comment in the thread, it was mentioned about the final look of the planet which was placed in the background. Mr. Wilde also made this short preview on how that look was achieved:
I admit I have a quite complicated way of doing my planets, but
it alsogives me more control over the final look. These are the basic
renders I did.
Earth surface/clouds lit by the key light.
Earth surface/clouds with 100% ambient light.
The atmosphere lit by the key light.
The city lights on the dark side of the terminator only.
Put the Earth key light layer above the Atmosphere layer and set it to 'soft light'.
Now clone the key light layer, set it to 'screen' and opacity to 30%. That way you get the terminator back (and he'll be always back) which previously vanished.
Now add the ambient texture layer, color correct it to give it a fairly blue color, and set it to 'screen' and opacity to 10%. Now we have a fill light for the dark side of the planet.
Now for the atmosphere, which is the tricky part and requires some messing around.
Clone the atmosphere layer. Add Gaussian Blur set to 2. Now clone this layer and Gaussian Blur it with a level of 4. Clone this layer and blur it with 8, clone it and blur it with 16, and again clone and blur it with 32. Now set all those layers except the bottom one to screen and you'll get this:
Reduce this bunch to one layer. Now you can enhance the saturation and play with the levels until you find a look of the atmosphere that pleases you. Sometimes when you raise saturation, you get ugly artifacts. You then have to blur the layer again to make them disappear.
Well, mine looks at the end like this:
Well, last step: add the city lights layer.
