A wide-ranging and delightful survey, The Possibility of Life is the kind of book that makes you exclaim 'Wow!' out loud while reading on the bus. To some extent, that’s because Green packs the book with fascinating facts.

Ms. Green’s book, alive with the color and drama of science fiction as well as scientific fact, helps us grasp that process of imagining.

While many books have been written about the search for extraterrestrial life, Green’s blend of scientific facts and science fiction reveals a sense of joy and wonder beyond the usual science-based cosmological studies or speculative fiction about aliens and UFOs. Ultimately, Green’s work reflects upon the nature of life and what it means to be human..

The Possibility of Life is not a book about aliens; it’s about human beings and the possibilities of our lives, together and alone.

Rather than taking up space with unnecessary conjecture, Green begins with history.
