How to draw a Nebulae?

Hi!,

Does someone know how to draw a nebulae in space. I could simply map a texture onto a sphere but it does not look nice. I could use some kind of particles with different colors but I don’t know how.

Thanks!

If you want to cruise trough the nebulae use some kind of volumetric fog technique. Else, use a skybox (for examples of both, try google).
