What does neb mean?
Neb is a rare noun with two distinct uses. In astronomy, it is an informal shortening of nebula, referring to a cloud of gas and dust that may appear bright enough to observe with the unaided eye. The expression planetary neb describes a particular kind of expanding stellar remnant, despite the misleading impression created by its name. In British dialectal English, neb can mean a nose, especially a prominent or distinctive one. The astronomical meaning is most likely to be encountered in informal writing, captions, and discussions of observation, while the nose meaning is regional and literary. For general astronomical writing, nebula is the clearer and more authoritative term. Knowing neb nevertheless offers a glimpse into both the shorthand of popular science and the vivid vocabulary of British dialects.

Where does neb come from?
The astronomical sense of neb is an abbreviated form of nebula, which comes from Latin nebula, meaning “mist” or “cloud.” Latin nebula also supplied the English words nebular, nebulous, and nebulosity, all of which retain the idea of cloudiness or gaseous diffusion. The separate dialectal sense meaning “nose” has a different historical development and should not be connected etymologically with the astronomical shortening.
How neb is actually used
The astronomical sense is informal and uncommon; nebula is preferred in formal writing. The sense meaning “nose” is chiefly British and dialectal, and may sound old-fashioned outside regional literature.
