Gazing into the night sky, children investigate our solar system, the universe, and major constellations. Star charts map the sky and help young astronomers navigate their way with the naked eye, binoculars, or telescopes. From Pluto to Pegasus, each entry examines a different heavenly body and answers the questions "how big and how far?" A special hand sky-measuring system that’s easy for kids to learn and use helps them understand scale and distance.
