"Professor Kolb brings us a refreshing set of chapters that provide an update on some of the most fascinating areas of astrobiology, including the origin of life, the search for habitable exoplanets, extremophiles, and the place of viruses in astrobiology. The diversity of chapters and information makes this an excellent read for those new to the field or those seeking new ideas."—Charles Cockell, The University of Edinburgh"A broad-ranging volume covering many different aspects of astrobiology, with engaging chapters containing up-to-date reviews by leading authors. Very accessibly written, suitable for senior undergraduate and graduate students. Each chapter finishes with a helpful glossary of terms, reflecting the strongly interdisciplinary subject matter, and useful review questions that could be used in seminar-based teaching. Overall a great astrobiology education resource."—Nicola McLoughlin, University of Bergen, Norway"A really comprehensive and unifying book, which will prove useful and enlightening not only to astrobiologists and evolutionary biologists, but also to anyone interested in life emergence and evolution in the Universe."—Professor Rolando Cardenas, Head of Planetary Science Laboratory, Universidad Central "Marta Abreu" de Las Villas
