Aurora

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind.

Nebulanoun

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

Nebulanoun

A white spot or slight opacity of the cornea.

Nebulanoun

A cloudy appearance in the urine

Nebulanoun

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.

Nebulanoun

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

Nebulanoun

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.

a clouded spot on the cornea causing defective vision.

Nebula

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