Nebulae
All the major nebula are given in this section. Brighter ones appear first.
Emission, reflection, dark and planetary nebula are included here.
A nebula is typically a gas or dust cloud. An emission nebula is illuminated by the stars inside it (e.g. the Orion Nebula). A reflection nebula is illuminated by a nearby star. A dark nebula is just a nebula with no nearby star to illuminate it (e.g. the Coal Sack Nebula). A planetary nebula is the outer layer blown off an old star, which typically forms a ring (e.g. the Ring Nebula). Finally, a supernova nebula is the remnant of an exploded star (e.g. the Crab Nebula).
