I place in a glass flask the following liquids or infusions, all very alterable on contact with ordinary air: beer-yeast water, sugar-beer-yeast water, urine, beet juice, and pepper water; then with the aid of a lamp, I draw the necks of the flasks to give different shapes. I then bring the liquid to a boil for a few minutes until the water vapors leave abundantly by the end of the drawn-out neck.... I then let the flasks cool. A strange thing happens that will astonish everyone accustomed to the delicacy of experiments relative to so-called spontaneous generation;... the liquid in the flasks remains indefinitely without alteration.. distribution, and future of life in the universe .

Informed by the discoveries and analyses of extrasolar planets and the findings from recent robotic missions across the solar system, scientists are rapidly replacing centuries of speculation about potential extraterrestrial habitats with real knowledge about the possibility of life outside our own biosphere--if it exists, and, if so, where. Casting new light on the biggest questions there are--how did we get here, and who else might be out there?--this third edition of Kevin W. Plaxco and Michael Gross\'s widely acclaimed Astrobiology incorporates a decade\'s worth of new developments in space to bring readers the most comprehensive, up-to-date, and engaging introduction to the field available.Plaxco and Gross examine the factors that make our Universe habitable, from the origin of chemical elements and the formation of the first galaxies and stars to the birth and composition of the planets. They describe the latest thinking about the origins of life, explain the evolution of metabolism and the development of complex organisms. In order to assess the limits for life elsewhere, they also explore life in extreme habitats and reveal how it informs the search for potential extraterrestrial habitats--ones that might support extraterrestrial life. New and updated illustrations enhance the book throughout.Sharing fascinating findings from the comet mission Dawn, the visit of New Horizons to Pluto, and the work of the Deep Carbon Observatory, which has revealed an incredible underground biosphere within our own planet, Plaxco and Gross weave together cosmology, astrophysics, geology, biochemistry, biophysics, and microbiology. From neutron star mergers to the survival skills of tardigrades, this fascinating book is an ideal primer for students or anyone curious about life and the Universe. Compiled by a team of experts, this textbook has been designed for elementary university courses in astrobiology. It begins with an examination of how life may have arisen on Earth and then reviews the evidence for possible life on Mars, Europa and Titan. The potential for life in exoplanetary systems and the search for extraterrestrial intelligence are also discussed. The text contains numerous useful learning features such as boxed summaries, student exercises with full solutions, and a glossary of terms. It is also supported by a website hosting further teaching materials. Written in an accessible style that avoids complex mathematics, this book is suitable for self-study and will appeal to amateur enthusiasts as well as undergraduate students. It contains numerous helpful learning features such as boxed summaries, student exercises with full solutions, and a glossary of terms. The book is also supported by a webstite hosting further teaching materials. This book offers an advanced introduction to the increasingly robust fields of extrasolar planets and astrobiology. No other text currently available applies this level of mathematics and physics, while also providing an extensive grounding in key issues of chemistry, biology, and geophysics. With extensive references to the literature and chapter-ending exercises, this????????????????book????????????????can be used as the core text for teaching undergraduate or introductory graduate level courses. The text????????????????will also????????????????provide astrobiologists with an indispensable????????????????User\'s Manual????????????????when quick reference to????????????????key mathematical and physical techniques is needed.????????????????????????????????A continually updated online component, fully cross referenced with the????????????????text, is also????????????????available. Foreword by Geoff Marcy. Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.About the Series: Oxford\'s Very Short Introductions series offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, Literary Theory to History, and Archaeology to the Bible. Not simply a textbook of definitions, each volume in this series provides trenchant and provocative--yet always balanced and complete--discussions of the central issues in a given discipline or field. Every Very Short Introduction gives a readable evolution of the subject in question, demonstrating how the subject has developed and how it has influenced society. Eventually, the series will encompass every major academic discipline, offering all students an accessible and abundant reference library. Whatever the area of study that one deems important or appealing, whatever the topic that fascinates the general reader, the Very Short Introductions series has a handy and affordable guide that will likely prove indispensable.#370 How did life on Earth begin? How common is it elsewhere in the Universe? Written and edited by planetary scientists and astrobiologists, this undergraduate-level textbook provides an introduction to the origin and nature of life, the habitable environments in our solar system and the techniques most successfully used for discovery and characterisation of exoplanets. This third edition has been thoroughly revised to embrace the latest developments in this field. Updated topics include the origins of water on Earth, the exploration of habitable environments on Mars, Europa and Enceladus, and the burgeoning discoveries in exoplanetary systems. Ideal for introductory courses on the subject, the textbook is also well-suited for self-study. It highlights important concepts and techniques in boxed summaries, with questions and exercises throughout the text, with full solutions provided. Online resources, hosted at www.cambridge.org/features/planets, include selected figures from the book, self-assessment questions and sample tutor assignments. Lunine (University of Arizona) examines key issues in astrobiology for upper-level undergraduate and beginning graduate students coming from physics, chemistry, geology, and biology backgrounds. Coverage encompasses the origin of the cosmos and the evolution of life, the mechanisms for maintenance of planetary habitability, the search for life else
