This text discusses a broad range of possible environments where alien life might evolve in our universe. It also uses current knowledge of chemistry, energy and evolutionary tendencies to consider possible life forms ranging from the familiar to the exotic.

With its groundbreaking research into the existence of extraterrestrials We Are Not Alone changed forever the scientific community’s debate on life in the universe.Exploring what forms extraterrestrial life might take and where it may reside, it provides a captivating tour of the Solar System and shows that it’s much more crowded than we previously realised.

Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today.Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself – if this is a highly improbable event,then we live in a rather “empty universe”. However, if this isn’t the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a “cosmic zoo”. The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don’t know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves.Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?

This class-tested textbook examines the basic elements of living systems: energy, chemistry, solvents, and habitats in crucial depth. These elements define the opportunities and limitations for life on other worlds. The book argues that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, the possibility of exotic forms of life based on backbones other than carbon, liquids other than water, and energy other than light. The authors offer an operational definition of life and summarize prevailing thoughts on plausible pathways for the origin of life on Earth and other worlds. They discuss remarkable adaptations to extreme environments, the nature and detection of geo- and biosignatures, the future and fate of living systems, and suggestions for the optimization of future exploratory space missions.The entire text has been thoroughly updated in this third edition, with new sections added on exoplanets, synthetic life,the search for extraterrestrial life, and a tour of the bodies in our Solar System for signs of conditions conducive for life. While informed speculation in this emerging field cannot be avoided, the authors have clearly distinguished between what is known as fact and what are reasonable expectations. They present an objective assessment of the plausibility of life on other worlds that is broad and deep enough for the expert and for use as an advanced text in astrobiology, while avoiding scientific jargon as much as possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.

Energy, chemistry, solvents, and habitats - the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space. While speculative considerations in this emerging field of science cannot be avoided, the authors have tried to present their study with the breadth and seriousness that a scientific approach to this issue requires. They seek an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter and avoid scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.The second edition thoroughly updates this text in view of the rapid progress in the field and a substantial amount of new material has been added, in particular sections and chapters on adaptation to extreme environments, the future and fate of living systems, life detection concepts based on the thorough analysis of the Viking missions and the issue around the meteorite ALH 84001, and - last but not least - recommendations for the optimization of future space exploration missions.From the reviews of the first edition:"[...] I know of no other book that reassesses the fundamentals of astrobiology in such way. This book is a tacit lesson in open-mindedness tempered with thorough scientific analysis. This is a very important book for all professional astrobiologists." A Ellery, International Journal of Astrobiology, 6 (2007) 182-183

Sind wir allein im Universum? Dieses Buch bietet eine einzigartige Perspektive auf die Frage, die die Menschheit von Anbeginn beschäftigt. In klarem und allgemein verständlichem Stil untersuchen zwei führende Forscher aus der Astrobiologie die verschiedenen Wege, die zu einer vielfältigen Biosphäre führen. Ist der Mensch eine galaktische Besonderheit oder entwickelt sich immer komplexes Leben auf Planeten, die lange genug bewohnbar sind? Leben wir in einem „einsamen Universum“ oder gibt es eine Vielzahl von Planeten mit komplexem und mikrobiellem Leben – ein "lebendiges Universum"?Schulze-Makuch und Bains führen den Leser durch die Geschichte des Lebens auf der Erde – von den ersten replizierenden Molekülen über die Photosynthese, die Erfindung von Sex zu intelligentem Leben. Indem sie sich auf die Funktionalitäten des Lebens, statt auf eine bestimmte Biochemie oder Anatomie konzentrieren, legen sie dar, warum wir denken sollten, dass fortgeschrittenes, komplexes Leben auf anderen Planeten als der Erde existiert.
