Features: On a clear night, let yourself enjoy the world's largest free show. Look up at the sky, and you'll see a dazzling spectacle—countless stars twinkling like pearls scattered on black velvet. You'll also find yourself singing the cheerful nursery rhyme: "Little star, so bright, what are you?" Did the stars come out tonight? If they did, are others watching them too? For centuries, astronomers have gazed at the heavens, trying to figure out our true place in the universe. Now, through the book "Astronomy," you can see what they have discovered. What are red giants? What is the relationship between red giants and green giants? How far away is the farthest object we can see? How long ago was the light that reaches our eyes emitted? Did the universe's "Big Bang" really happen? From Galileo to quasars, from pulsars to the celestial poles, the secrets of the night sky and the faces of its explorers will be revealed in the book.
