Unfolding our universe

the long version

"Unfolding Our Universe is a comprehensive and accessible introduction to astronomy. With text and illustrations, it takes readers to the heart of the Universe - explaining the facts, concepts, methods and frontiers of astronomical science. The book can be read right through without referring to any mathematics. For the more ambitious reader, key points are developed in more detail and basic mathematics provided in self-contained boxes." "Full color throughout and a very readable text make this book a delight for the casual reader to browse, while the clear and concise explanations will appeal to amateur astronomers, science teachers and college and university students taking an introductory course on astronomy."--Jacket.
