Examines each of these parameters in crucial depth and makes the
argument that life forms we would recognize may be more common in our
solar system than many assume.
Considers exotic forms of life that would not have to rely on carbon as
the basic chemical element, solar energy as the main energy source, or
water as the primary solvent and the question of detecting bio- and
geosignatures of such life forms, ranging from earth environments to
deep space.
Seeks an operational definition of life and investigate the realm of
possibilities that nature offers to realize this very special state of
matter.
Avoids scientific jargon wherever possible to make this intrinsically
interdisciplinary subject understandable to a broad range of readers.
