Combine two different textures so that one appears in the shadows as Earth rotates? [duplicate]

Question

I just watched to this amazing example on how to animate Earth: https://www.youtube.com/watch?v=0yz_-U7t8AU

So I ask: is it possible to combine the two different textures below so that the night Earth (with lights on) appears in the shaddow region as Earth rotates?
