In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.
The types of nebulae that exist in the universe include bright, dark and emission nebulae. Different nebulae are often named for their shape. More information can be found on "Sea and Sky".
