Welcome to the paper galaxy, a cosmic collection of fantastic three-dimensional, modular paper projects. Some are realistic (a meteorite), others fanciful (an alien ship), and they range from very simple to elaborate. Just copy or trace the pattern—the instructions tell you how—and then cut, paste, and paint the paper to construct sun bursts, stars, black holes, moons, comets, even Martians that you can decorate with antennae. And once you've made a few, take a tip on hanging and displaying your handiwork. Budding astronomers and artists will love every one...because they're all out of this world!
