Outer space, often simply called space, comprises the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace (and terrestrial locations). Contrary to popular understanding, outer space is not completely empty (i.e. a perfect vacuum) but contains a low density of particles, predominantly hydrogen plasma, as well as electromagnetic radiation. Hypothetically, it also contains dark matter and dark energy.

The term "outer space" was first recorded by H. G. Wells in 1901. The shorter term space is actually older, being first used to mean the region beyond Earth's sky in John Milton's Paradise Lost in 1667.
