space alien
Visitor from beyond
A space alien is an intelligent being from another planet or celestial body—the extraterrestrial of science fiction and UFO speculation.
The term distinguishes such creatures from the earthly sense of alien (a foreigner or outsider): The movie features space aliens landing in rural Iowa.
Often shortened to just alien when context makes the meaning clear.
