This is a list of diffuse nebulae. Most nebulae are diffuse , meaning that they do not have well-defined boundaries. Types of diffuse nebulae include emission nebulae and reflection nebulae .
Only 36 stars were known to be in this nebula but the Chandra telescope increased the number of known stars to 160. Lagoon Nebula: 110 ly (34 pc) [44] H II region: Veil Nebula: 100–130 ly (31–40 pc) [45] Supernova remnant: Located in the Cygnus Loop: NGC 3576: 100 ly (31 pc) [46] Emission nebula: N41: 100 ly (31 pc) [47] Emission nebula ...
The nebulae listed by Barnard have become known as Barnard objects. [2] A 1919 version of the catalogue listed 182 nebulae; [3] by the time of the posthumously published 1927 version, it listed 369. [4]

This is a list of protoplanetary nebulae. These objects represent the final stage before a planetary nebula. During this stage, the red giant star begins to slowly expel its outermost layers of material. A protoplanetary nebula usually glows by reflecting the light from its parent star.
