Cosmic Outer Space Birthday Party Decoration Ideas


If the birthday boy dreams of being an astronaut and loves outer space, host a cosmic outer space birthday party for him. Transform your house into an out-of-this-world party venue by using decorations that reflect your theme. Everything from your wall decorations to your table centerpieces can be made into part of cosmic outer space. Don't forget an outer-space-themed birthday cake to complete your extraterrestrial celebration.

Wall Decorations

  • Create a dark room full of neon planets and stars for your cosmic outer space birthday party. While you certainly don't want to paint your walls black, you can drape them in dark fabric, and close your windows to prevent sunlight from getting in. Attach stick-on glow-in-the-dark star stickers to the ceiling to create a constellation in your home. Or find lights that reflect and rotate stars around your room. Use cardboard and some paint to create planet cut-outs, which you can attach to the fabric draped on the walls. If you're artistic, draw life-size aliens on pieces of butcher paper and mount them on the walls.

Table Decorations

  • Dress up your tables to reflect the cosmic outer space theme. Drape your tables in silver tablecloths. Create an outer-space-themed centerpiece to place atop your tables. Cut out shapes of stars and space ships using card stock, and attach the shapes to 6-inch dowel rods. Fill a tin can with sand, insert the dowel rods in the sand, and your outer-space themed centerpiece is complete.

    Pick up plastic foam balls from a local craft store, and paint them to look like planets. Hang the planets from the ceiling above your table. Write each guest's name on a plastic star, and leave it at each place setting. Guests can take these outer-space-themed place cards home as favors.


  • Your food can serve as a decorative element of your party, as well as a functional one. Make star-shaped finger sandwiches using a cookie cutter. Easy-to-make cheesesticks can serve as "alien fingers." Decorate cupcakes or sugar cookies to look like planets. If the birthday girl wants a cake instead, choose a sheet cake with fondant aliens on it or a round cake iced to look like a planet.
