This book deals with all there needs to be known about the origin and nature of life on Earth as well as the possibilities of life elsewhere in the Universe. The book in electronic form enables the author to regularly update the subject matter to enable readers keep abreast of the latest news from outer space.

This book was first published in 2001. Dr Tritton is a professional astronomer with Britain’s Open University, tutoring astronomy, planetary science and cosmology. He continues to be enthusiastic about making the latest scientific discoveries understandable to a wider public and devotes much of his time to talking about astronomy to non-scientific audiences. In the light of the constant stream of information on new discoveries from extraplanetary telescopes such as the Hubble Space telescope, he spent a considerable time in updating this book, ready for publication in this electronic age.

'Earth, Life and the Universe...exploring our cosmic ancestry' is a book written by Dr Keith Tritton and Peter Willsher is the editor.
