Unlike a clip tied to a single film, meme or viral moment, Aurora Borealis is used online as a general atmospheric sound for night-sky and nature content. Short-video creators reach for it when a scene needs a quiet sense of wonder without dialogue or music taking over, and its one-second length makes it easy to drop into edits, transitions and photo montages. That flexibility, rather than a famous origin, explains why it keeps appearing in dreamy, travel and relaxation-style posts.
