I was aked to do a space scene, with the sun emitting its power towards the earth. The whole scene was done in After Effects, on an ultra wide resolution as it was used for on-site projection. You can also see the moving scene used in here.

Here is a quick breakdown of the different passes: some stock images, Trapcode Particular, Element 3D for the earth and moon, a hand-made sun from fractal noise and shine, more particles, and color correction to tie everything together.
