1. Sky Glow

Break glow sticks and shake the liquid onto a black cloth. Cover the ceiling with the cloth once it dries and allow the sky to glow like a galaxy. You could even add glitter or sparkles to really make the decoration twinkle. You can also find some supplies here.

2. Shiny Stars

Cut out cardboard stars and wrap them in aluminum foil. Hang them from the ceiling using a clear fishing line to add consistent decorations throughout your venue.

3. Celestial Lights

Incorporate the use of black and neon lights to create cool lighting effects at the party. 

4. Paper Tableware

Search for tableware with stars, moons, or other celestial markings on them. You could also simply use a mix of black and neon green plates, napkins, silverware, etc.

5. Fun Fabric

Use fabric with stars or planets on it to cover the walls or ceiling. Black fabric is another option to create the darkness of the sky.

6. Floating Balloons

Use white and silver balloons to decorate. Input helium and allow them to float freely. You can also try to find mylar balloons in the shape of stars or moons to accent the regular balloons.

7. Cosmic Confetti

Collect confetti in the shapes of stars and moons to sprinkle around tables. Glitter is a great accessory to the confetti to help glam up the table settings.

8. Celestial Cutouts 

Assemble poster boards to resemble shooting stars, planets, aliens, or even UFOs. Attach the cutouts to the wall or hang them from the ceiling using a fishing line.

9. Galactic Garland

For an easy and beautiful pop of decor, add a star-shaped garland as a fun backdrop. You can hang the stars from your ceiling, or drape them above doorways, for an out-of-this-world decoration.

10. Rocket Launch

Rocket launching kits can be purchased online, but you can also create do-it-yourself rockets with household supplies.

11. UFO Toss

Staple or glue two paper plates together to create a flying saucer shape. Allow guests to decorate the UFOs with paint, stickers, or other crafting supplies. Guests should throw the saucers as far as they can into space. The guest who achieves the greatest distance is the winner.

12. Be a Star

Play music for a karaoke contest. Allow guests to perform and try to achieve star status. For a twist, you could only play songs that involve stars or celestial objects such as “Shooting Stars” or “Dark Side of the Moon.”

13. Astrology Readings

Learn to read the horoscopes in the constellation and galaxy to the delight of your guests. You could also try a tarot card reading. Hire a professional or allow guests to take turns reading each other’s futures.

14. Asteroid

Ask guests to stand in a circle. Provide a balloon not filled with helium to a player. That player should say a person’s name before they hit the balloon to him or her. The player whose name was said needs to hit the balloon and say another guest’s name. Add multiple balloons to make the game more chaotic and fun.
