nebula
Cosmic gas cloud
A nebula is a vast cloud of gas and dust in space, often where stars are born or where they have died.
Some nebulae glow from the light of nearby stars; others appear as dark patches against brighter backgrounds.
The term extends figuratively to anything hazy or cloud-like: a nebula of uncertainty.
In medicine, a nebula is a cloudy spot on the cornea.
Plural: nebulae or nebulas.
