A nebula could be either bright or dark.Gas and dust in the nebula reflect light. Dark nebula dust hide light in the background.


From pp 86-97, Deep Sky Objects,Levy:
The cosmic dust of a nebula consists of carbon, silicate or iron particles. Each particle is coated with water, ice, methane and ammonia.
