Astrobiology: Origins from the Big-Bang to Civilisation

The general topic of this book concerns the origin, evolution, distribution, and destiny of life in the Universe. It discusses the transition from inert matter to cellular life and its evolution to fully developed intelligent beings, and also the possibility of life occurring elsewhere, particularly in other environments in our own and other solar systems. Advanced extraterrestrial life can be probed by means of radioastronomy in the well-established project of search for extraterrestrial intelligence. The text pays special attention to the robust growth in our capacity to search for microorganisms, as well as signals of extraterrestrial life,
