reflection nebula

(nebula made visible by light it scatters from nearby stars)

A reflection nebula is a cloud of dust that is scattering EMR from one or more nearby stars, making it glow enough to be seen as a light nebula rather than a dark nebula (dark region on the sky).

A cometary nebula is one that resembles a comet, and represents one of the ways some reflection nebula can appear from our point of view. In the classical case, it is a diffuse nebula lit by a star in such way that it resembles a comet with tail.
