The Pale Blue Data Point – An Earth-Based Perspective on the Search for Alien Life by Jon Willis; The University of Chicago Press; 256 pages; Hardcover, $26.00.
As a professor of astronomy at the University of Victoria in British Columbia, Willis has written a highly-engaging, captivating and timely book.
In the preface of this volume, the author calls attention to the dramatic landscapes right here on home planet – the Earth. “Our pale blue data point offers many opportunities to learn about the life that exists upon it,” adding that our world offers clues as to the prospects for life elsewhere.
Indeed, the past 30 years has served up a “golden generation” of exoplanet discovery, Willis explains. Moreover, this book offers the reader a look not only of astrobiology as a science, but what astrobiology looks like in the field – rich in scientific unknowns and eye-opening findings.
Willis underscores the work of exploration, from use of the submersible-equipped E/V Nautilus to contemplate the seas of Saturn’s and Jupiter’s moons to the mountaintop observatories in Chile that scout out extrasolar planets, as well as listening in on dolphins in the Bahamas to envisage the minds of alien intelligences.
The Pale Blue Data Point offers six enlightening and discerning chapters, such as “Twenty Thousand Pings Under the Sea: In Search of Alien Oceans,” “Swimming with Stromatolites: The Hunt for Martian Fossils,” and “So Long and Thanks for All the Fish: A Dolphin-Led Guide to Alien Communication.”
Given the rise of astrobiology and the search for life elsewhere in the cosmos, Willis asks “can a collection of tangential ideas, drawn from all points of the scientific compass, be made to fit into the circle of a new discipline?”
This book offers the reader the answer to that question, expertly written to spotlight astrobiology in action.
Lastly, the volume concludes with a “Further Travels” section, a guide for the reader’s own astrobiological opportunities, “whether metaphorically or indeed literally,” Willis suggests.
