The chapters are arranged as follows: Chapter 1 is a broad introduction to the cosmos, with an emphasis on where we might find life. In Chapters 2 and 3 Professor Jones discusses life on Earth, the one place we know to be inhabited. Chapter 4 is a brief tour of the Solar system, leading us in Chapters 5 and 6 to two promising potential habitats, Mars and Europa. In Chapter 7 the author discusses the fate of life in the Solar system, which gives us extra reason to consider life further afield. Chapter 8 focuses on the types of stars that might host habitable planets, and where in the Galaxy these might be concentrated. Chapters 9 and 10 describe the instruments and techniques being employed to discover planets around other stars (exoplanetary systems), and those that will be employed in the near future. Chapter 11 summarizes the known exoplanetary systems, together with an outline of the systems we expect to discover soon, particularly habitable planets. Chapter 12 describes how we will attempt to find life on these planets, and the final chapter brings us to the search for extraterrestrial intelligence, and the question as to whether we are alone.
