Astrobiology is an expanding, interdisciplinary field investigating the origin, evolution and future of life in the universe. Tackling many of the foundational debates of the subject, from discussions of cosmological evolution to detailed reviews of common concepts such as the 'Rare Earth' hypothesis, this volume is the first systematic survey of the philosophical aspects and conundrums in the study of cosmic life. The author's exploration of the increasing number of cross-over problems highlights the relationship between astrobiology and cosmology and presents some of the challenges of multidisciplinary study. Modern physical theories dealing with the multiverse add a further dimension to the debate. With a selection of beautifully presented illustrations and a strong emphasis on constructing a unified methodology across disciplines, this book will appeal to graduate students and specialists who seek to rectify the fragmented nature of current astrobiological endeavour, as well as curious astrophysicists, biologists and SETI enthusiasts.

'This book is not merely a review of past and present astrobiological and cosmological endeavours, but a critical discourse of various key scientific publications, theories and methodologies … This volume provides an excellent survey of and discourse on astrobiological concepts … this biologist with her limited cosmology understanding found the book enlightening.'

'… written in a language and at a level that is accessible to other astronomers and astrobiologists … Best of all, the book ends with twenty pages of notes and twenty-one pages of references. Just for this wonderfully comprehensive bibliography of the philosophy of astrobiology, this book deserves to be on the shelf of any astrobiologist’s library.'

'Ćirković's book is not an astrobiology textbook with facts and worked examples, but is probably the best book on the philosophical implications of life in the universe, in the universe.'
