As nouns the difference between nebula and nebulium
is that nebula is a cloud in outer space consisting of gas or dust (e.g. a cloud formed after a star explodes) while nebulium is a supposed element proposed as a result of spectral analysis of light from a nebula; the emission lines concerned are now known to be due to doubly-ionized oxygen.
