24 Space Themed Nursery Ideas That Are Truly Out of This World

A space themed nursery is one of those ideas that works for any baby — boy, girl, or gender-neutral — and it grows with your child in a way that pastel animal prints just don’t.

Stars, planets, rockets, and moons give you so much to play with visually, and the color palette almost picks itself. Deep navy, soft gray, inky black, warm white. It’s a dream to decorate.

I fell in love with the idea when a friend sent me a photo of her son’s room at 2 a.m. — a deep blue ceiling dusted with hand-painted stars and a rocket mobile hanging over the crib. I couldn’t stop thinking about it.

Since then I’ve been collecting nursery inspiration obsessively, and space keeps coming up as one of the most versatile and genuinely beautiful themes you can choose for a baby’s room.

Whether you want something soft and dreamy or bold and graphic, there is a version of this theme for you. I’ve pulled together 24 of my favorite ideas to help you figure out exactly what direction to take your own nursery in. Let’s get into it.

24 Space Themed Nurseries

From galaxy murals to minimalist star mobiles, these 24 rooms show just how many directions you can take a space theme — pick what speaks to you and run with it.

1) Galaxy Mural & Navy Crib Bedding

A floor-to-ceiling galaxy mural is the anchor of this nursery. Deep navy and indigo swirl across the wall, with painted planets — Saturn’s rings included — floating in the mix. It’s bold without being harsh, especially against the warm honey-toned wood floors and the white crib sitting right in front of it.

The navy crib bedding picks up the wall color beautifully. That continuity keeps things looking intentional. A woven basket on the floor, a textured cream rug, and bamboo shades at the window stop the room from feeling too dark or heavy.

Tip: if a painted mural feels like too big a commitment, look for peel-and-stick wallpaper murals — many come in this exact deep galaxy style and are fully removable.

2) Constellation Ceiling & Gray Tufted Crib

A dark navy ceiling covered in painted constellation lines instantly pulls the eye upward — and that’s exactly the point. It makes the room feel bigger. More dramatic. Like bedtime is actually an event.

The gray tufted crib grounds the space without competing with the ceiling. White walls keep everything from feeling too heavy, and the natural jute rug adds warmth underfoot. The knit pouf is a practical touch — great for late-night feeds when you need somewhere to rest your feet.

Tip: If you want the constellation effect, use a stencil kit and glow-in-the-dark paint so the ceiling literally lights up after dark.

3) Vintage Rocket Wallpaper & Red Throw

Perfect for parents who want something bold but not overwhelming. The deep navy wallpaper covered in retro rockets, moons, and planets does all the heavy lifting as an accent wall — no extra decor needed on that side of the room.

The white crib keeps it clean against all that pattern. A chunky red knit throw draped over the crib rail pulls one of the wallpaper’s accent colors out into the room. Smart. The warm wood dresser and woven basket stop the space theme from feeling cold or clinical.

Tip: hang two or three framed space prints on the shiplap wall opposite, just like shown here, to tie the theme across the room without papering every wall.

4) Natural Wood Crib & Planet Wall Decals

A wooden crib mobile hung with a crescent moon and gold stars is one of the easiest ways to bring a space theme into a nursery without painting a single wall. The light birch wood tones keep everything airy and calm. Simple. Intentional.

The planet wall decals scattered across the white walls do a lot of heavy lifting here. They add color and visual interest without overwhelming the room. Paired with that cream round rug and the natural wood dresser, the whole space feels collected rather than chaotic.

If you love this look, skip the bold colors and stick to muted, watercolor-style planet decals. They work so much better in a neutral nursery like this one.

5) Navy Canopy & Star-Print Rug

Deep navy fabric drapes over a crisp white crib, pulling the whole room into a moody, after-dark atmosphere without painting a single wall dark. The accent wall behind it carries a subtle celestial print — planets, moons, stars — that ties right into the canopy’s color.

It works because the rest of the room stays light: soft gray glider, cream curtains, warm wood tones.

That star-print rug is doing a lot of heavy lifting here. It keeps the space theme grounded at floor level, which is something I don’t see people think about enough. The woven basket and rattan pouf add texture without competing.

Tip: Mount your canopy rod slightly higher than feels natural — it makes the ceiling look taller and the whole setup more dramatic.

6) Felt Planet Mobile & Rocket Ship Rug

Bold primary colors are doing all the heavy lifting here. The handcrafted felt planet mobile above the white crib is the clear star of the room — red, yellow, navy, and orange orbs hang at different heights, giving the ceiling real visual interest without a single nail hole in the wall.

Below it, the rocket ship rug ties the whole palette together. It anchors the space and gives you a color roadmap for every other buying decision in the room. Match your throw pillow to the yellow Saturn ring. Pull the navy into your rocker blanket.

Floating shelves keep the astronaut figures and wooden decor accessible but off the floor. Smart use of vertical space.

7) Matte Black Wall & Gold Star Decals

That orbital pendant light hanging from the ceiling? It ties the whole room together without trying too hard. The deep matte black accent wall is covered in scattered gold star decals at different sizes, which gives the ceiling-to-floor effect of an actual night sky without a single drop of paint on the other walls.

The mustard yellow glider is a smart move here. It punches warmth into what could easily feel cold and dramatic. The white crib keeps things grounded. Crisp. Clean.

Tip: pair a constellation area rug like this one with the black wall so the celestial theme carries to the floor — it stops the dark wall from feeling heavy in a small space.

8) Lavender Galaxy Wallpaper & Star Cushion

A soft watercolor galaxy mural in muted lavender and lilac does a lot of heavy lifting here. It brings the space theme in without going dark or dramatic. The white crib and white dresser keep everything light and airy against it.

That star-shaped floor cushion on the shaggy cream rug is such a good touch. Small detail, big payoff. The gray starprint pendant light overhead ties it all together without competing with the wall.

If you love this look, search for peel-and-stick watercolor space murals — they come in gender-neutral pastel colorways and are fully removable, which is a win for renters.

9) Honey Pine Dresser & Astronaut Shelf Display

A deep navy accent wall dotted with gold stars sets a calm, adventurous tone without feeling overwhelming. The floating shelf above the changing dresser is where the real personality lives — a lineup of astronaut figurines, a tiny rocket, and a globe make it feel curated rather than cluttered.

The honey-toned pine dresser doubles as a changing station, keeping the look warm and grounded against that dark wall. Open shelving below holds folded linens and a woven basket — storage that’s actually functional.

Tip: Group shelf decor in odd numbers and mix heights. Three astronauts plus a rocket plus one globe reads as intentional, not random.

10) Star Map Triptych & Navy Crib Sheet

Perfect for parents who want a nursery that feels smart and considered. Three framed star map prints hung in a tight row above the crib do a lot of heavy lifting here — they read as art, but they’re deeply on theme. No planets, no rockets. Just the actual night sky.

The navy crib mattress sheet grounds the whole palette. Gray walls, a white spindle crib, warm wood legs and a Beni Ourain-style rug keep everything balanced without feeling cold.

Tip: order star maps dated to your baby’s birth date or due date. Same visual impact, way more meaning.

11) Moon Phase Wood Discs & Planet Rug

A row of carved wood moon phase discs hung above the crib does a lot of work here. It keeps the space theme going without leaning on dark walls or busy wallpaper. Simple. Understated. Effective.

The navy planet rug is the real anchor of the room. It pulls the whole celestial theme down to floor level, which is smart for a nursery where babies spend a lot of time on the ground. The muted earth tones in the planet print stop it from feeling too dark or overwhelming.

Tip: if you source the moon phase discs from a laser-cut wood shop, you can usually request them in different stain shades to match your crib or rocker finish.

12) Rocket Floor Lamp & Constellation Rug

Deep navy walls set the mood instantly. A tall rocket-shaped floor lamp anchors the corner beside the white crib, casting a warm amber glow that doubles as a soft night light. It’s charming without being loud.

The star-mapped constellation rug pulls the whole floor together, and the planet wall decals add just enough detail to keep the space theme going across every surface. A knit pouf and neutral armchair keep things cozy and functional for late-night feeds.

Tip: a novelty floor lamp like this one does real work — night light, decor piece, and focal point all in one. Skip a separate lamp on the dresser and let this carry the room.

13) Navy Galaxy Crib Sheet & Planet Wall Decals

The deep navy galaxy-print crib sheet is doing a lot of heavy lifting in this nursery. It anchors the whole space theme without a single bold paint color on the walls — just clean white and those scattered planet and star decals doing their thing.

I love how the wall decals feel light and airy. No commitment, totally removable. The moon balloon on the upper right adds dimension without crowding the room.

Pro tip: pair a busy printed sheet like this with a simple white quilted blanket on top — it balances the pattern and keeps the crib from feeling too visually heavy.

14) Earthy Wall Decals & Rattan Crib

That little wooden toy telescope on the coffee table? It pulls the whole room together. The wall decals here skip the typical navy-and-silver space palette entirely — planets, moons, and stars in warm terracotta and sand tones feel grounded and soft rather than bold.

The rattan crib is doing a lot of heavy lifting. It keeps the look natural and airy, which lets the celestial wallpaper decals stay the visual star. A jute rug and woven pendant light add texture without competing.

If you love this look, layer in burnt orange curtains like these to warm up a north-facing room. It makes a huge difference in natural light.

15) Fairy Light Ceiling & Planet Wall Decals

Hundreds of warm fairy lights strung across a deep navy ceiling do something a projector just can’t — they stay on all night without cycling off. The effect is a genuine starry sky overhead, and it pairs perfectly with the planet and rocket decals spread across the accent wall.

The white convertible crib keeps things grounded so the dark ceiling doesn’t overwhelm the space. Smart move. A space-print floor pouf and matching crib bedding tie the theme down to floor level without going overboard.

Tip: Use adhesive cable clips to run your fairy light strands in arching rows — it makes the ceiling look intentional, not tangled.

16) Solar System Wall Decal & Planet Knobs

Soft and educational at the same time. A large solar system wall decal runs across the main wall, with each planet labeled by name — great for a room that grows with your child well past the baby stage.

The white dresser does double duty as a changing station. Those planet-shaped drawer knobs are a small detail that ties the whole theme together without going overboard. I love a room where the theme shows up in the hardware.

Tip: pair a labeled solar system decal like this with a planet-print rug to reinforce the learning element at floor level too.

17) Charcoal Walls & Crescent Moon Neon Light

If you want a nursery that feels like outer space after dark, deep charcoal walls are the move. The near-black paint wraps the whole room and makes every accent pop — the glowing crescent moon neon light especially. It hangs in the corner like a nightlight you’d actually want to look at.

The white crib, shaggy Beni Ourain-style rug, and gray glider keep things from feeling too dark or heavy. Balance matters here. Floating ledge shelves hold board books within easy reach for those late-night feeds.

Tip: pair a neon moon light with glow-in-the-dark wall decals — rockets, stars, planets — so the room has a second layer of magic once the main lights go off.

18) Cream Tufted Rug & Moon Star Embroidery

The cream shag rug with woven moon and star motifs does all the heavy lifting here. It anchors the space theme without a single bold color in sight. Soft. Quiet. Still clearly celestial.

A round natural wood crib paired with sheer star-printed curtains keeps the whole room airy. The open wood cubby holds a wicker basket for easy toy storage — practical and on-theme at the same time.

Tip: a wooden rocket toy on the shelf adds a playful nod to the theme without committing to loud decor. Easy to swap out as your baby grows.

19) Saturn Mural & Navy Accent Wall

Navy blue meets creamy white, and the whole room feels like you’re floating somewhere between Earth and Saturn. That oversized planet mural is the centerpiece — bold, detailed, and surprisingly soft in tone. It doesn’t scream. It pulls you in.

The white crib sits right beneath the rings, which makes for the most incredible focal wall. A neutral glider, warm wood dresser, and layered rugs keep the rest of the room grounded so the mural gets all the attention it deserves.

Tip: if you’re going this route, keep every other surface simple. One statement wall is all you need.

20) Built-In Reading Nook & Gold Star Wallpaper

A built-in reading nook is one of the smartest moves you can make in a space nursery. The navy cushion anchors the whole room. Gold star wallpaper peeks out from the alcove ceiling — subtle, sweet, and so effective.

Flanking shelves keep space books, rocket figurines, and plush toys organized without cluttering the walls. That round wood-framed mirror adds depth to the nook without competing with the theme.

My tip: style the shelves with a mix of books facing outward and small 3D objects — it keeps things visually interesting at a child’s eye level as they grow.

21) Constellation Curtains & Planet Mobile

Look up. The hanging planet mobile above the crib is doing a lot of quiet work in this room, but those navy constellation-print curtains steal the show. Deep and rich against the soft gray walls, they frame the window without darkening the whole space.

The light-colored crib keeps things airy so the bold curtains don’t overwhelm. A knit navy pouf on the floor ties the dark tones together at ground level. Smart move.

Tip: if your curtains are this pattern-heavy, keep bedding simple — the white quilt here is exactly right. Let one element lead.

22) Gold & Silver Mixed Metallic Celestial Decals

Gold and silver together. The mix of metallic planet and star wall decals is what makes this nursery stand out — it avoids the one-tone trap that makes so many themed rooms feel flat. The brass pendant light ties the gold tones together without feeling forced.

The space-print area rug does a lot of work here. Planets, stars, and constellations scattered across a soft cream base keep the theme going underfoot without overwhelming the white walls. Smart layering.

If you go this route, stick to two metals max — gold and silver read as intentional. A third finish and it starts to look cluttered fast.

23) Macramé Moon Wall Hanging & Woven Pouf

Soft, earthy, and quietly cosmic. This boho space nursery pulls off something I rarely see — a celestial theme that feels warm instead of cold. The large macramé wall hanging with a crescent moon cutout does the heavy lifting. No paint, no wallpaper, just fiber and texture.

Navy crib bedding ties in the space theme without going full galaxy. The basket of planet-inspired felt balls on the floor is such a clever touch — décor that doubles as a sensory toy later on. I love that.

Tip: anchor the boho-space look with one strong fiber piece like this macramé, then keep everything else neutral so the celestial details pop.

24) Dark Star Accent Wall & Wooden Floating Shelf

Small nurseries can pull off big themes. A deep navy accent wall covered in gold star decals creates serious impact without swallowing the room — especially when the rest of the walls stay light and neutral to keep things airy.

A single floating wood shelf above the crib does a lot of work here. Wooden planet figures and a ceramic rocket keep the theme tight without cluttering the space. The round space-print rug and navy blanket tie the palette together at floor level.

Tip: keep your furniture in light natural wood tones to stop a dark accent wall from making a small room feel heavy.

Colors That Work Best in a Space Themed Nursery

Deep navy is the obvious starting point — it reads as night sky immediately, and it works beautifully with white furniture. But you don’t have to go dark.

Soft lavender, pale gray, and dusty blue all read as ‘space’ when you pair them with the right accents like gold stars, silver moons, or planet prints. The key is picking a lead color and letting the theme accessories do the heavy lifting.

If you’re nervous about dark walls in a small nursery, try an accent wall only. Or skip the dark entirely and go with a warm white room with galaxy bedding and a star mobile — you still get the theme without committing to a moody palette.

Metallics — especially gold and brass — are your best friends here. They add the sparkle of stars without overwhelming the room.

One combination I keep coming back to: deep navy walls, warm white trim, natural wood furniture, and gold metallic accents. It’s cozy, it’s dramatic, and it photographs beautifully for the nursery reveal shot you’ll definitely want.

Common Mistakes to Avoid in a Space Nursery

The biggest mistake I see is going overboard with every space element at once — rocket wallpaper AND a planet mobile AND star ceiling AND astronaut wall art. It starts to feel like a toy store rather than a calming room for a baby.

Pick two or three hero elements and let the rest of the room breathe. A great mural with simple white furniture is far more striking than a room where every surface is competing for attention.

Another thing to watch: cheap glow-in-the-dark stickers. They look great at first, but they yellow quickly and peel unevenly. If you want a starry ceiling effect, invest in quality decals or, better yet, have someone paint a simple star pattern with real glow paint.

It lasts so much longer and looks ten times better. The ceiling is one of the first things a baby stares at from the crib — it’s worth doing right.

Finally, think about longevity. Babies become toddlers fast, and a room that works at 6 months should still feel cool at age 5. Avoid overly babyish rocket prints in favor of slightly more graphic or illustrative space imagery — it’ll age with your child and save you a full redecoration in a year or two.
