This is basically mapping a perlin noise texture onto a sphere
representing the sky, layering another texture over it to make the sky
and clouds near the sun glow, adding a lens flare, and using fog. You
could use wrinkles, turbulated bozo, or a custom pattern done with
isosurface functions for the cloud pattern.
To animate them, you might try averaging or multiplying several patterns
together(maybe using isosurface functions to get it exactly right), and
translating them in different directions.
