The emission type of these objects absorbs ultravi
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. 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. Name these objects, including the Crab, that are interstellar clouds.
