Introduction
Some Halloween decorations go big and bold. But celestial-themed window displays? They bring a different kind of magic. There’s something deeply enchanting about stars, moons, constellations, and glowing galaxies that gives your home an almost dreamlike vibe.
If you’re leaning into a Halloween aesthetic that’s more mystical than monstrous, more ethereal than eerie — celestial is the way to go. Whether you’re decorating a shopfront or your living room window, there’s endless inspiration floating in the night sky. Let’s turn your windows into a portal to another universe — no spaceship required.
Ready to explore 18 out-of-this-world Halloween window display ideas with a cosmic twist? Let’s light it up, moonchild.
1. Lunar Phases with Backlit Film
Want something minimal yet mesmerizing?
Use translucent window film cut into moon phases — from crescent to full. Backlight it with soft LED strips behind sheer curtains, and you’ve got an elegant, glowing window that screams “celestial chic.”
Why it works:
- The subtle glow pulls attention without looking too busy.
- It can stay up beyond Halloween — perfect for moon lovers year-round.
- Combine with a little dry ice or fog machine for a mysterious effect at night.
2. Starry Night Silhouette Cutouts
Can a few paper cutouts really elevate a display? Absolutely.
Craft black silhouette panels featuring stars, telescopes, witches on brooms, and planets. Tape them to the inside of your window and backlight them with warm-toned fairy lights or battery-powered LED panels.
Style Tip: Add a soft navy-blue sheer fabric over the window for an added sense of depth — like a night sky in layers.
3. Floating Moon and Stars Mobile
How can you bring movement into a static display?
Hang shimmering stars and moons from the window frame using clear fishing line. Use holographic cardstock or metallic paper so they twinkle and reflect light with even the smallest breeze.
Add-ons to consider:
- Glow-in-the-dark paint for a nighttime surprise
- Mini bells or wind chimes for an airy, witchy vibe
4. Constellation Projection Display
Ever thought of projecting the night sky inside your home?
Use a star projector to beam real constellations onto your curtains or window coverings. You can even get Halloween-themed ones with spooky celestial overlays.
Why it stands out:
- No crafting needed — just plug and glow
- Great for nighttime parties or trick-or-treater wow factor
- Works beautifully from both inside and outside
5. Glitter Galaxy Window Clings
What if you want something temporary but stunning?
Pick up galaxy-themed window clings. Think swirling nebulas, meteor showers, and rings of Saturn. Layer different colors and shapes to build a scene.
Pro Tip: Add some fairy lights on the window frame to enhance the shine of the glittery clings.
6. Mystic Crystal-Lit Display
Love a witchy twist on your celestial theme?
Display crystal props — like amethyst towers, quartz clusters, or selenite wands — right along your windowsill. Pair them with soft purple or white LED lights to make them glow from within.
Want to make it interactive?
Add mini labeled tags like “Moonstone for Intuition” or “Citrine for Abundance” to give your display a mystical, educational touch.
7. Cloudy Galaxy Layers
Can clouds and stars go together in one window? Totally.
Stretch out cotton batting or polyester fiberfill across the bottom of your window like clouds. Tuck mini string lights or soft purple lights inside the “clouds” for a dreamy effect.
Make it even more magical by:
- Sprinkling in glow-in-the-dark stars
- Adding tiny silver star confetti
- Hanging paper UFOs or bats above the “sky”
8. Celestial Witch Silhouette Scene
Looking for something with a Halloween twist?
Create a scene of a witch flying across the moon, stars glittering in the background. Use large silhouette decals or cutouts and stick them to the inside of the window.
Bonus Tip: Add a twinkling LED moon behind her to illuminate the entire silhouette from behind. Spooky meets starry — perfection.
9. Planet Parade Display
Ever seen planets lined up across a window? It’s a showstopper.
Cut out cardboard or foam balls, paint them like Mercury through Neptune, and hang them in order from the top of your window frame. Use fishing wire so they look like they’re floating.
Want it more Halloween-y?
Give Saturn a witch hat, or add tiny spider webs between the planets.
10. Moon Phases Garland with Dried Florals
Can boho and spooky mix? They sure can.
Create a horizontal garland with all the moon phases using clay or thick black cardboard. Intertwine it with dried lavender, eucalyptus, or even fake crow feathers.
Hang it across:
- Your window frame
- The top of a bay window
- Inside curtains for a peekaboo celestial effect
11. Tarot-Inspired Celestial Panel
What’s more mystical than Halloween and tarot together?
Print or paint giant tarot-style window panels featuring the moon, stars, sun, and celestial figures. Use frosted adhesive vinyl or sheer fabric so light still passes through.
Design Tips:
- Stick to a muted palette: navy, cream, gold
- Border each panel with faux golden fringe or mini star chains
12. Magic Mirror Window Illusion
Want something interactive and mysterious?
Install a reflective film on your window and frame it with black lace, lights, and a sign that says “Speak to the Spirits” or “Gaze Into the Beyond.” The illusion? You see yourself — but so does the viewer outside.
Add more intrigue by placing:
- Floating ghost decals
- A crystal ball prop inside the window
- Smoky incense nearby for atmosphere
13. Cosmic Bats and Star Trails
Bats are Halloween staples — but let’s elevate them.
Cut out bats from silver or iridescent paper. Place them flying diagonally across the window, trailing behind shooting stars made with string lights or foil streamers.
It creates:
- Movement
- Sparkle
- A dynamic nighttime vibe that’s playful and stylish
14. Crescent Moon & Witch’s Ladder
Want to go full witchcore? Here’s your moment.
Hang a large crescent moon cutout in the center of your window. From its tip, dangle a witch’s ladder — a long strand of ribbon with beads, bones, charms, feathers, and bells.
What does it symbolize?
Protection, intention, and connection to the spirit realm — just the touch your Halloween setup needs.
15. Floating Astral Orbs
Can you DIY your own floating planets? You bet.
Grab lightweight foam balls, paint them in celestial hues (think metallic purples, midnight blues, and gold), and suspend them at different lengths from the curtain rod.
Enhance with:
- Tiny glow sticks tucked inside
- Swirling galaxy paint textures
- Mini LED tea lights for a floating-light effect
16. Star-Crossed Lovers Scene
Want something with a story?
Design silhouettes of two celestial figures — one a moon goddess, the other a starry spirit — reaching for each other across the panes. Use window-safe chalk markers or removable vinyl.
To deepen the scene:
- Add constellations behind them
- Frame the window with trailing fairy lights or hanging crystals
- Include a tiny black cat perched at the corner
17. Astronomer’s Observatory Vibes
Who says Halloween can’t be scientific and magical?
Set up a little scene that looks like an astronomer’s window from the 1800s. Use paper scrolls, telescope props, star maps, and vintage books on the windowsill.
Lighting tip:
Use a warm Edison bulb-style string light to mimic candlelight for that cozy, scholarly ambiance.
18. Solar Eclipse Drama Display
Want something bold and unique? Try an eclipse.
Create a layered cutout of the moon partially covering the sun using matte black and gold paper. Backlight it to create a glowing eclipse effect.
The finishing touch?
Hang shooting star garlands below, and place a glowing orb (your “sun”) on the sill for added dimension. Your neighbors won’t be able to look away.
