space aliens
Beings from elsewhere
Space aliens are intelligent beings from other planets or elsewhere in the universe.
The term usually implies creatures who might visit or contact Earth, as in science fiction scenarios: Do you believe in space aliens?
While "alien" alone can mean any foreigner, "space alien" specifies the extraterrestrial sense, distinguishing little green men from immigration status.
