Sir Patrick Moore is the undisputed expert on the stars and planets. His first Guide to the Moon was published more than fifty years ago, and reprinted many times; amid all the excitement of inter-planetary exploration and the rush to journey into space, Sir Patrick has never lost his fascination with our nearest heavenly body. This book explores his intimate knowledge of the Moon's surface structure, its origins, its place in the general scheme of the Universe and its close relationship with Earth. What was once remote and mysterious is now almost conquered territory, our knowledge extended immeasurably by the Apollo missions and more recently lunar probes. Yet the questions remain. Is there evidence to show there was once life on the Moon? Is there life there now? What does the Moon tell us about the beginning of life, or the end of life even, on Earth? In his new book, Sir Patrick reviews our present knowledge of the Moon in the lucid and lively manner he has made all his own.
