This is Earth with Blender Cycles materials. In fact, it is a conversion of Blender Guru's famous "Realistic Earth" tutorial to Cycles. Everything from the tutorial is there, including the atmosphere, the night lights/color map switch, etc. All textures are packed in the blend file. All of them are free for use (from NASA). One texture, clouds, was modified to give it alpha values (which made the conversion to Cycles easier). All textures were resized to be smaller. The color ramp needs to be slightly adjusted to make the night lights appear at the correct time. There is 250 frames of animation. The Earth spins 15 degrees. It spins correctly (opposite the Blender Guru tutorial). The compositor has a glow effect in place, as well as adding an image in the background. Previously, the background image was applied as a texture to the world material. Also, the number of samples is set low (20), so you may want to set it higher. If you have any suggestions, let me know, and I will make corrections to this blend.
