Some famous examples of these are the Trifid, Eagle, and Lagoon, and the type of these objects formed in the creation of a white dwarf is the planetary type.
The emission type of these objects absorbs ultraviolet light and emits visible light, and that type often is known as an H two region because it contains large amounts of atomic hydrogen. Those H two regions are also classifed as the diffuse types of these, as are supernova remnants.
