Since the early 1600s, telescopes have helped us examine the stars. Early telescopes used two glass lenses to focus light. Today, we use mirrors in the same way as glass, but mirrors are lighter and easier to make than lenses. To see dim objects that are far away, these mirrors must be very large. They're much larger than the average hobbyist telescope. With this volume, readers will learn about the components of a telescope and the role each component plays. They will read about different types of telescopes and the objects that each can help them see in great detail.
