Things You'll Need
Painting an outer space scene lets your imagination run wild, as you try to best represent the cosmos. An outer space scene makes a great mural for a child's bedroom, and is a good way to add some color to a wall. Outer space might seem alien to you, but that doesn't mean you can't let your creativity take over, filling in the gaps for what you don't know about the universe. Paint planets, stars, rocket ships, comets and more.
Painting Outer Space
Paint all intended walls or other surfaces black to create a primer coat for your outer space scene. Let this coat dry while you think about how you want your space scene to be arranged. If you are designing a mural, first sketch out your space scene on a piece of paper. Think about what planets, stars, UFOs, nebulas, suns and/or galaxies you want to decorate the "space" of the black paint. Sketch your design using rough shapes to represent these objects and celestial beings.
Start painting by splattering white paint over the black background coat to create stars. Let this dry. Then, sponge various dark colors of paint over the scene, to create a nebulous effect. Start on the top with a blue sponging effect, and use a plasma pink or similar color toward the bottom. This will add some dimension to your space scene and give it color to grab your viewer's attention.
Wait until the sponged paint has dried, and then paint a circle to start making a planet. For example, Earth starts as a blue circle; once that paint has dried, you can use green paint to illustrate land masses. Don't forget the Earth's moon—a small gray dot orbiting nearby. The Sun is essential to any space scene, and you can paint it as a yellow circle larger than the size of your Earth. Add a UFO by painting a disk with gray paint. Draw aliens in the "cockpit" of the space craft before closing it off with a circular line around their heads.
Lightly shade your planets with sunlight by sponge-dabbing black paint for shadow effect in the opposite direction of where you place your sun.
