Each night, as we sleep, a beautiful celestial dance is taking place. While the earth is still, it's actually spinning and circling the sun. The milky way galaxy, billions of stars and billions of galaxies whirl into the ever-expanding space called our universe. Young readers (ages 4 - 8) can explore the earth, our solar system, galaxies beyond, and the universe as a whole. A great book with delightful art that will fascinate future space travelers!
