Baby showers have a funny way of turning ordinary living rooms into little worlds of imagination.
One moment it’s just a table and a few chairs. The next moment there are balloons floating everywhere, cupcakes decorated with tiny stars, and someone is hanging decorations that make the entire room look like a night sky.
A space-themed baby shower is one of those themes that instantly makes people smile.
It’s playful.
It’s creative.
And it works beautifully for both boys and girls.
Parents often love this theme because it feels whimsical without being overly complicated. A few stars, a few planets, and suddenly the room feels like a tiny universe.
Guests enjoy it too because space themes naturally create fun decorations, adorable desserts, and photo backdrops that look amazing in pictures.

This phrase has become one of the sweetest baby shower sayings, and it fits perfectly with a space theme.

Moon-shaped cookies are one of those decorations that feel simple but end up being incredibly charming on a space-themed baby shower table.
Instead of placing regular cookies on trays, many hosts use crescent moon cookie cutters to create soft moon shapes. Once baked, the cookies can be decorated with pale yellow icing, soft gray frosting, or edible shimmer dust to mimic the glow of the moon.
Some bakers like to add tiny silver stars around the cookie edges or paint delicate crater-like patterns using edible food coloring.
When displayed on white cake stands or marble trays, these cookies immediately look elegant and on-theme.
A beautiful way to present them is by arranging the cookies around the main cake like a little “orbit” of moons.
Guests almost always reach for them because they look delicate and special, but they’re still easy finger food.
And if you package a few in small clear bags with star-shaped stickers, they can double as adorable take-home treats.
14. Galaxy Cupcake Tower
A cupcake tower is one of the easiest ways to create a dramatic dessert display.
For a space-themed baby shower, cupcakes can be decorated with galaxy-style frosting using deep purples, blues, and soft pink swirls.
Many bakers create the effect by blending two frosting colors together while piping so the swirl resembles a tiny galaxy.
Edible glitter or silver star sprinkles add the finishing touch.
When the cupcakes are stacked on a tall tiered stand, the display looks like a spiral galaxy rising above the table.
Parents often place the baby shower cake at the very top of the stand so the entire dessert display feels like the center of the “solar system.”
Cupcake towers also work well because guests can easily grab one without needing plates or forks.
15. “A Little Star Is On the Way” Welcome Sign
A welcome sign is often the very first thing guests see when they arrive at the baby shower.
For a space theme, a sign that says “A Little Star Is On the Way” sets the tone instantly.
The sign can be printed on a dark navy background with soft gold stars scattered around the lettering.
Some hosts place the sign on a wooden easel near the entrance so it feels like a little announcement.
Adding a few balloons or star garlands around the sign helps it stand out even more.
Guests often stop there to take photos when they arrive.
It’s a simple decoration, but it quietly introduces the theme before guests even step into the party space.
16. DIY Rocket Party Favors
Party favors don’t need to be complicated to be memorable.
Rocket-themed favors are especially fun because they match the space theme perfectly and can be surprisingly easy to assemble.
Some hosts fill clear candy tubes with colorful chocolates and attach little rocket stickers.

A popular option is attaching a small tag that says:
“Thanks for celebrating our little star.”

It’s a small gesture, but people love having something sweet or playful to take home.
17. Hanging Planet Decorations
Ceiling decorations can completely transform the feeling of a room.
Instead of focusing only on tables and walls, hanging planets above the party space makes guests feel like they’ve stepped into a tiny solar system.
Paper lanterns or balloons painted like planets can be suspended from the ceiling with clear fishing line.
Some hosts create planets using colored balloons and add rings around them to resemble Saturn.
When placed at different heights across the room, the decorations look like planets floating in space.
Children especially love looking up and pointing out the different planets.
It adds movement and depth to the party decorations without taking up any table space.

Placing small gold star confetti or mini planet decorations along the runner adds extra detail.
Some hosts also place small glass jars with fairy lights on the tables so the lights glow softly against the constellation pattern.
The result feels calm, magical, and very “night sky.”
19. Rocket Diaper Cake Centerpiece
Diaper cakes are a baby shower classic, but turning one into a rocket shape makes it perfect for a space theme.
Instead of stacking the diapers in a simple tier, the diapers are rolled and arranged into a tall rocket form.
Decorative paper flames can be attached to the base so the rocket looks like it’s launching.
Small star stickers or baby-themed decorations can be added along the rocket body.
The finished piece works beautifully as a centerpiece on the gift table.

They also photograph beautifully in party photos.
23. Milky Way Snack Mix
Snack mixes are always helpful for baby showers because they’re easy to prepare and easy for guests to grab.
A “Milky Way Mix” can include popcorn, chocolate candies, pretzels, and small marshmallows.
The colors naturally resemble a galaxy when mixed together.
Serving the mix in small cups or paper cones makes it simple for guests to enjoy while chatting.
It’s the kind of snack that quietly disappears throughout the party.

This idea adds a meaningful touch to the celebration.
