You have every reason and right to look at the night sky as the greatest free show in the universe. Most amateur stargazers—in fact, most professional astronomers—are strongly attracted by the great beauty of the sky. But the sky is more than beautiful. Celestial objects are full of information just waiting to be interpreted—information like: how distant the stars and galaxies are, how large they are, and whether they are moving toward or away from us.

How does the information reach us?

It travels to us in the form of electromagnetic radiation, a small portion of which is visible light. We begin this chapter by defining light and then talk about how we can most effectively collect it to see more of the solar system and the universe.
