As the leaves turn shades of crimson and the nights grow longer, Halloween invites us to explore the darker, more mysterious side of life—and the universe. While haunted houses and pumpkin patches are traditional, this year, consider a different kind of spooky, one that looks up rather than around. Planetariums offer the perfect intersection of spine-tingling space lore and fascinating science, making them ideal, unconventional spots to visit in October. Here are some of the most engaging, fun planetariums across the United States to visit this Halloween, where the stars feel closer and the legends of the night sky take on a haunting twist.
Spooky Cosmos at the Adler Planetarium, Chicago, IllinoisThe Adler Planetarium, located on the edge of Lake Michigan, is a crown jewel of American astronomy, but come October, it embraces the cosmic unknown. Their shows often delve into the eerie side of the universe, focusing on topics like black holes, the fate of the universe, and the mythology behind constellations. During the Halloween season, the atmosphere within their immersive theaters changes. Instead of just learning about stars, you might find yourself exploring the “lunar mysteries” or watching a sky show dedicated to the darker side of astronomy. The museum often hosts special evening events, transforming into an atmospheric, stargazing party that feels both scientific and slightly sinister in the best way possible.
Cosmic Fright Night at Griffith Observatory, Los Angeles, CaliforniaPerched atop Mount Hollywood, the Griffith Observatory is iconic, but in October, it provides the perfect, moody backdrop for a Halloween adventure. While it offers unparalleled views of the city below, its Samuel Oschin Planetarium puts on a show that can range from awe-inspiring to wonderfully spooky. Imagine gazing at the stars while hearing the myths and legends of ancient civilizations—many of which include terrifying monsters, forbidden romances, and gods behaving badly. The observatory’s architecture itself feels like a scene from a classic film, and walking its halls under a full autumn moon is an experience every space enthusiast should have.
Eerie Encounters at the Hayden Planetarium, New York CityLocated within the American Museum of Natural History, the Hayden Planetarium is a, if not the, world-renowned center for space education. During Halloween, it bridges the gap between science fiction and science fact. Shows like “Dark Universe” take a serious look at the mysterious, invisible forces that make up the vast majority of our cosmos—dark matter and dark energy. The sheer scale of the Hayden’s digital projectors, which can turn the dome into an immersive, swirling galaxy, creates an environment that feels both awe-inspiring and slightly dizzying—perfect for a Halloween thrill. The surrounding museum, with its vast collection of fossils and gems, only adds to the atmosphere of discovery.
Haunted Skies at the Fiske Planetarium, Boulder, ColoradoFor those looking for a more interactive and sometimes theatrical experience, the Fiske Planetarium at the University of Colorado Boulder is a must-visit. Throughout the year, they offer a diverse array of shows, but in October, they are known to incorporate themed laser shows and specialized presentations that explore the darker, more fantastical side of astronomy. They often mix in live music or themed narratives, making it a lively, engaging spot for a, well, “spooky” evening. The surrounding campus and the crisp Colorado autumn air provide the perfect atmosphere for an evening of cosmic, Halloween-themed exploration.
The Mystical Night Sky at the Hayden Planetarium, Boston, MassachusettsSituated within the Museum of Science in Boston, the Hayden Planetarium (not to be confused with the NYC namesake) is a hub for high-tech, engaging shows. Around Halloween, this venue often leans into the “science of the spooky,” perhaps exploring the astronomy behind ancient, festive traditions or examining whether cosmic events could explain historical, mysterious happenings. The planetarium’s high-tech projector system makes for incredibly vivid, detailed journeys through space, which, when set to a more dramatic, moody narrative, becomes an unforgettable Halloween activity.
Visiting a planetarium this Halloween offers a unique way to celebrate the season. It combines the thrill of the unknown with the wonder of the cosmos, allowing you to explore the darker, more mysterious corners of the universe, all from the comfort of a comfortable, climate-controlled dome. Whether it’s tales of cosmic monsters, the mystery of black holes, or just the stunning, profound darkness of space, these venues provide a memorable and intellectually stimulating alternative to traditional Halloween festivities. Exploring the skies this October might just make you look at the stars in a whole new, slightly terrified, light.
