Designing a nursery is one of those sweet, surreal moments in the lead-up to baby’s arrival. You’re creating a world they’ll dream in, grow in, and maybe, someday, ask about the stars in. And if you’re drawn to galaxies, rockets, and softly glowing planets? A space-themed nursery brings that dreamy, wide-open-sky feeling right indoors.
It’s not about decking every inch in midnight blue or hanging a giant moon on the ceiling (although that can be pretty awesome). It’s about creating a peaceful, wonder-filled space that whispers of adventure.
Not sure how to create a space-themed nursery? I’ve gathered space nursery ideas that’ll have you starry-eyed before the crib even arrives.
From whimsical rockets to glowing stars, outer space nursery decor can create an environment that’s both calming and full of imagination.
1. Galaxy Wall Mural
Painting a galaxy across the nursery wall instantly transforms it into a galaxy-themed baby room, opening a window to another world. Swirls of purples, blues, and silvery whites create that deep-space vibe that’s dreamy, not overwhelming.
You can go custom with hand-painted designs if you’re artsy—or use peel-and-stick murals that look impressively real with zero brushwork required. Behind the crib or as an accent wall, it becomes the quiet star of the room (pun fully intended).
2. Star Projector Night Light
A room gently lit by drifting stars after dark feels like stepping into a bedtime dream—calm, a little wondrous, and unexpectedly soothing. A projector casts constellations, moons, and even nebula-like clouds across the ceiling—perfect for winding down after a long day of snuggles.
Some rotate slowly, others shift colors—either way, it turns bedtime into a peaceful little show. You might even find yourself lingering a while after baby’s asleep, just watching the stars spin.
3. Moon and Stars Mobile
Mobiles are a nursery classic for a reason—and this one’s got just the right mix of whimsy and calm. Felt stars, tiny moons, maybe even a little Saturn or two, slowly twirling above the crib like a lullaby in motion.
Soft neutrals like cream, grey, and dusty gold work beautifully, or you can go bolder with navy and mustard. Hang it from a simple wooden arm or directly from the ceiling—it’s a sweet way to bring the sky a little closer.
A room wrapped in navy and white carries an easy sense of calm—cool, balanced, and quietly elegant without trying too hard. It’s clean, classic, and gives that perfect night-sky contrast without darkening the mood.
Think deep blue walls with white cribs and pale curtains—or flip it and use navy in the accents: rugs, pillows, wall art. A few warm metallics like brass or soft gold give it a hint of glow without going overboard.
5. Constellation Wallpaper
Constellation prints bring quiet magic to the walls—no planets or rockets needed. Look for patterns with fine lines and scattered stars, almost like they were drawn with a silver pen across velvet.
Soft tones work especially well here—charcoal, dusty blue, even a warm beige base. Whether it’s a feature wall or the whole room, the result feels peaceful and just the right amount of otherworldly.
6. Rocket Ship Shelf
Add a little lift-off to your nursery with a rocket-shaped shelf. It’s playful without being over the top, and doubles as decor and storage. Stack a few bedtime books inside, tuck in a stuffed astronaut, or display tiny shoes like they’re precious cargo.
Whether it’s wall-mounted or freestanding in a corner, it brings a gentle nod to space travel that still feels soft and nursery-friendly.
7. Glow-in-the-Dark Ceiling Stars
Tiny glow-in-the-dark stars scattered across the ceiling bring a little quiet surprise once the lights are out. They charge up during the day, then softly light the ceiling like a private little galaxy.
Stick them in clusters or trace out a few constellations. It’s a sweet, simple way to add wonder—and when you’re rocking the baby to sleep, it’s kind of lovely to have a sky to look at, too.
8. Plush Planets
Soft, squishy planets add texture and fun without veering into clutter. You can find full sets with all eight planets—or just mix and match a few favorites in velvety fabric and muted tones.
Pile them in a basket next to the rocker, or scatter them across a shelf. They’re part toy, part decor, and totally adorable for tummy time later on.
9. Astronaut Stuffed Toys
A tiny astronaut nestled in with the bears and bunnies adds a touch of adventure to the usual crew. Look for ones with metallic boots, stitched visors, or even custom embroidery for an extra special keepsake.
Tuck one into the crib for decoration or set it on a shelf like it’s keeping watch over the room. It adds personality without shouting for attention.
10. Solar System Wall Decals
Peel-and-stick solar system decals are a quick way to transform a blank wall into a mini orbit. Arrange planets in proper order, cluster them artistically, or let them float over the changing table like little celestial guides.
They’re easy to reposition and won’t damage paint, which makes them perfect if you’re renting—or just want flexibility as baby’s room evolves.
11. Toy Basket and Hamper
A soft, roomy toy basket with star or rocket prints keeps the clutter corralled while still staying on theme. Toss in plush planets, rattles, or books, and it becomes a little corner of the galaxy all its own.
Look for collapsible canvas bins or rope baskets with embroidered or printed space details—they’re cute enough to leave out and sturdy enough to last.
12. Crescent Moon Pillow
A crescent moon-shaped pillow, nestled on the rocker or crib, adds both shape and softness. Velvet or fleece fabrics in pale gold, ivory, or slate grey give it a dreamy feel, almost like a lullaby you can hold.
It’s the kind of detail that quietly anchors the space. Not loud, not flashy—just a gentle nod to nighttime.
13. Space-Themed Mobile Above Changing Table
Mobiles don’t have to live above the crib. Hanging one over the changing table gives baby something interesting to watch during wiggles and diaper changes. Think little felt planets, rockets, or floating stars slowly twirling on invisible threads.
It turns a practical corner of the room into something a little more enchanted—and, if we’re being honest, can buy you a few precious seconds of calm.
14. Personalized Constellation Art
A print of the night sky from the exact date and place of your baby’s birth feels both cosmic and incredibly personal. Framed above the crib or dresser, it becomes a quiet centerpiece of the room—simple, beautiful, and meaningful.
Some versions even let you add names or quotes, creating a keepsake that’ll still feel special years from now.
15. Astronaut Wall Decor
A floating astronaut on the wall adds instant character to the nursery—like someone’s mid-mission, just drifting by with a quiet sense of wonder. You can go minimalist with a black-and-white print or playful with a 3D cutout or decal, complete with a trailing tether.
Position it near the crib, bookshelf, or even “floating” among some planets. It’s a small touch that brings a big sense of story, like the room’s very own spacewalk is happening right outside the frame.
16. Hanging Moon Lamp
A moon lamp gives off that soft, silvery glow that makes bedtime feel a little more peaceful. The best ones have a realistic texture—craters and all—so it actually looks like a little moon floating in the room.
Hang it in a corner or place it on a nightstand for a quiet, ambient light that’s both practical and poetic. It glows just enough for nighttime feedings without waking everyone up completely.
17. Milky Way-Inspired Rug
A nursery floor gets a lot of love—from first steps to sleepy storytimes—and a rug inspired by the Milky Way brings in that swirling, starry feel underfoot. Look for soft patterns in dusky blues, cloud whites, or hints of metallic thread.
It anchors the room and adds softness where it counts. Plus, it gives baby a cozy spot to stretch out and explore the universe one roll at a time.
18. Star Garland
Draping a garland of tiny stars along a bookshelf, above a window, or across the crib wall adds an easy layer of magic. Fabric, felt, metallic paper—whatever the material, it catches the light and adds movement.
Some sparkle, some shimmer, and some are quietly matte—but they all add that sweet sense of playfulness that makes a nursery feel like a nursery.
19. Book Nook with Space Stories
Tucking a low shelf into a quiet corner and filling it with space-themed board books creates a little retreat made for slow afternoons and early reading habits. Add a soft pouf or a mini rocker, and you’ve got the coziest launch pad for little imaginations.
Include classics like Goodnight Moon and There’s No Place Like Space!—it’s a corner that’s as much about bonding as it is about decor.
20. Rocket Lamp
A lamp shaped like a rocket adds instant charm and a bit of fun, especially in corners that could use a glow. Look for ceramic or metal designs in soft, warm tones—nothing too bright or novelty-store loud.
Set it on a dresser or shelf and let it softly light the room during wind-down time. It’s the kind of piece that sticks around long after babyhood.
21. “To the Moon” Quote Art
Sometimes the simplest prints say the most. A framed quote like “Love you to the moon and back” or “Dream big, little one” adds a layer of sweetness that ties the room together.
Choose soft script or typewriter fonts in neutral tones, maybe with a tiny star or moon graphic tucked in. Hang it above the changing table or near the crib—it’s like a whispered blessing on the wall.
22. Cosmic Growth Chart
A growth chart designed like a rocket climbing into the stars turns those milestone marks into a little adventure. Each inch climbed is like a new planet reached. You can find wall decals, canvas hangings, or even wood rulers with star maps or moon phases etched in.
It’s a sweet way to track those early years—and it adds height and interest to an empty wall or behind a door.
23. Starlight Canopy
Drape a soft, sheer canopy over the crib or reading nook and tuck in tiny battery-powered lights along the top. It feels like stargazing from inside a dreamy tent.
Pick one in a dusky grey or soft ivory, then let the glow peek through like scattered fireflies. It’s cozy, calming, and just a little magical.
24. Planet Drawer Knobs
Swap out the knobs on your dresser or changing table for little planets, stars, or rocket shapes. It’s a small change that makes a big difference, and it’s honestly kind of fun every time you open a drawer.
Mix colors and shapes or keep it subtle with brushed gold stars—whatever fits your version of a tiny universe.
25. Hanging Planet Models
Suspend miniature planets from the ceiling like they’re floating mid-orbit. You can hang them in a corner, over a reading chair, or above a changing station for a little visual surprise.
Look for lightweight paper or foam versions, or even paint your own if you’re feeling crafty. It’s one of those details that brings the solar system to life—in the coziest, most nursery-appropriate way.
26. Night Sky Curtains
Soft, blackout curtains sprinkled with tiny stars or moons do double duty: they block out naptime sun and add another layer of theme to the space.
Navy, charcoal, or cream tones with subtle patterns work best. They frame the windows beautifully and pull the whole room together without shouting for attention.
A Room That Feels Like a Dream
Designing a space-themed nursery isn’t just about decorating—it’s about creating a little haven full of wonder. A place where lullabies echo like radio signals through the galaxy and stuffed astronauts stand guard as your little one drifts off.
Whether you’re decorating for a baby boy or simply love cosmic style, these are some of the best nursery ideas for a baby boy space theme that combine comfort with creativity.
Soft lighting, plush planets, and just enough sparkle to make it feel like bedtime in a storybook sky. The nursery becomes not only a room, but a quiet invitation to look up—and dream big.
