alien life
Beings from elsewhere
Alien life refers to living organisms that originate somewhere other than Earth—hypothetical creatures from other planets, moons, or elsewhere in the universe.
The term ranges from microbes in Martian soil to intelligent beings in science fiction: Scientists search for signs of alien life on Europa.
Also called extraterrestrial life.
