Life may unfold in various forms throughout the universe, constrained by universal physical laws and consistent principles of organic evolution, but propelled to great variety in detail by local conditions and the specifics of planetary history. What is known of the chemical and physical conditions of any planetary environment and its history enables us to make educated and plausible speculations about the nature and history of life on that world.

Within our Solar System, there is an enormous diversity of planetary environments. On Earth, life evolved on a geologically complex, water-rich world, which today has an oxidizing atmosphere, although this was not always the case. On Mars, the surface is bitterly cold and dry, and the atmosphere very thin. Whether or not life ever existed on the Red Planet is a matter for speculation, but we do know that early in its history, Mars was a warmer, wetter world. Today Venus is a planet with an incredibly hot surface and a dense choking atmosphere, and it seems unlikely, although not impossible, that life could ever evolve here. On the gas giant planets, such as Jupiter and Saturn, it is possible that life might exist in the dense atmospheres of these cloud covered worlds, and might even have evolved on some of their exotic moons such as the sulphur-rich, volcanic world Io, Icy Europa with its possible sub-surface ocean, or Titan with its lakes of liquid petroleum gas on the surface.

Discussions of the great variety of life forms that could evolve in these diverse environments have become particularly relevant in recent years with the discovery of around 300 exoplanets in orbit around other stars and the possibilities for the existence of life in these planetary systems.

From the reviews:

"Cosmic Biology discusses the feasibility of life in the scorching cloud decks of Venus or within the volcanic violence of lo. ... This neat trick holds up a mirror to our own efforts at characterising the extrasolar planets we're now discovering. ... long data tables, information dense diagrams and sections that sometimes read like expanded bullet point lists gives the volume the feel of a textbook. ... a great book to push your horizons if you're already familiar with the themes of astrobiology ... ." (Lewis Dartnell, Sky at Night Magazine, August, 2011)

"The text, which is intended for nonscientists, are novel and distinctly important scientifically. ... The core of the book covers case history examinations of possible biological planets, moons, and exoplanets. For those who teach about the possibility of life on other planets, this book provides an excellent introduction to these alternative worlds and, in doing so, accomplishes more than the authors' modest claims in the preface. Summing Up: Recommended. All levels/libraries." (P. K. Strother, Choice, Vol. 48 (11), July, 2011)
