Nebula vs. Nebulous — What's the Difference?

A nebula (Latin for 'cloud' or 'fog'; pl. nebulae, nebulæ or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases.

Nebulous is a post-apocalyptic science fiction comedy radio show written by Graham Duff and produced by Ted Dowd from Baby Cow Productions; it is directed by Nicholas Briggs. The series premiered in the United Kingdom on BBC Radio 4.

A cloud of gas and dust in outer space, visible in the night sky either as an indistinct bright patch or as a dark silhouette against other luminous matter.

In the form of a cloud or haze; hazy

A clouded spot on the cornea causing defective vision.

(of a concept) vague or ill-defined

A diffuse cloud of interstellar dust or gas or both, visible as luminous patches or areas of darkness depending on the way the mass absorbs or reflects incident light or emits its own light.

Cloudy, misty, or hazy.

Lacking definite form or limits; vague

A cloudy spot on the cornea.

Of, relating to, or characteristic of a nebula.

(astronomy) A cloud in outer space consisting of gas or dust (e.g. a cloud formed after a star explodes).

Vague or ill-defined.

A white spot or slight opacity of the cornea.

A cloudy appearance in the urine.

Cloudy; hazy; misty.

A faint, cloudlike, self-luminous mass of matter situated beyond the solar system among the stars. The term was originally applied to any diffuse luminous region. Now, technically, it is applied to interstellar clouds of dust and gases (diffuse nebula). However distant galaxies and very distant star clusters often appear like them in the telescope, such as the spiral nebula in Andromeda, known now to be a distant galaxy.

Of, pertaining to, or having the appearance of, a nebula; nebular; cloudlike.

A white spot or a slight opacity of the cornea.

Lacking definite form or limits;

A medicinal liquid preparation intended for use in an atomizer

Lacking definition or definite content;

Cloudiness of the urine

An immense cloud of gas (mainly hydrogen) and dust in interstellar space

(pathology) a faint cloudy spot on the cornea
