Astronomy: The Definitive Guide is the perfect handbook for all who are interested in our place in the universe. Prepared under the direction of consultant editor Robert Burnham, the guide includes hundreds of photographs, illustrations, and sky maps that bring to life the intriguing subject of astronomy.

The guide is divided into two sections. The first, "Discovering the Universe", explains our changing understanding of earth's place in the universe and provides an up-to-the-minute guide to astronomy today. It describes the main celestial bodies and explores the big questions raised by our evolving understanding of the universe. Also included is advice on selecting the most appropriate equipment for skywatching and tips on becoming a successful viewer.

The second section, "A Guide to Celestial Objects", is a field guide to the night sky. It includes hundreds of maps and photographs, with sections on the sun, moon and planets, stars, nebulas and galaxies, as well as monthly star charts and sky tours of both northern and southern hemispheres.
