SPRINGERBRIEFS IN ASTRONOMY HOW LIKELY IS EXT...

What does existing scientific knowledge about physics  chemistry  meteorology and biology tell
us about the likelihood of extraterrestrial life and civilizations? And what does the fact that
there is currently no credible scientific evidence for the existence of extraterrestrial
biospheres or civilizations teach us? This book reviews the various scientific issues that
arise in considering the question of how common extraterrestrial life is likely to be in our
galaxy and whether humans are likely to detect it. The book stands out because of its very
systematic organization and relatively unbiased treatment of the main open question. It covers
all relevant aspects of many disciplines required to present the different possible answers. It
has and will provide undergraduates with a stimulating introduction to many of these fields at
an early stage in their university careers  when they are still choosing a specialty. The
difficulties and the range of possible answers to the title question are carefully addressed in
the light of present understanding. The resulting perspective is distinctly different from
those suggested by most other books on this topic.
