interstellar
Spanning celestial voids
Interstellar means between or among stars: interstellar space, interstellar travel.
The word describes the vast regions of a galaxy outside individual star systems, or objects and phenomena that cross those distances.
Interstellar dust clouds eventually coalesce into new stars.
The term gained wider cultural currency from the 2014 science fiction film of the same name.
