Review

"[Jon Willis] conveys great enthusiasm alongside necessary scientific skepticism."—Wall Street Journal"Energizing. . . . Through humorous, concise, accessible writing, Willis eloquently presents the growing—though still circumstantial—evidence that we are not alone."—Publishers Weekly (starred review)"[Willis] clearly lays out reasons why alien life could exist on astronomical bodies near Earth."—Winnipeg Free Press"A concise overview of astrobiology and what we know—and, more importantly, what we don’t—about the search for life elsewhere in our solar system and beyond."—The Space Review"All These Worlds Are Yours is a serious but accessible examination of the prospects for finding life elsewhere in the universe. From the solar system to planets around other stars, this is a lively guidebook for where life could be and how we can go about looking for it."—Sean Carroll, author of The Big Picture: On the Origins of Life, Meaning, and the Universe Itself"Jon Willis has written an engaging primer on astrobiology that is both comprehensive and conversational. All These Worlds Are Yours covers everything under the sun—and far beyond—about the hunt for alien life."—Lee Billings, author of Five Billion Years of Solitude: The Search for Life Among the Stars"A brilliantly written summary of the classical work on the chemistry of life, and the latest results in the exploration of moons and planets within, and the search for planets without, our Solar System."—Steven Benner, author of Life, the Universe, and the Scientific Method

Jon Willis's book is first rate. While there have been many books written on the search for life in the universe this author really delivers the goods. The subject is up-to-date and comprehensive. The science good and it is a breezy, easy read. The writing style, at times a bit quirky, but it keeps you thoroughly engaged in the topic. From the author's writing style you can tell he is a very egaging teacher in the classroom. The chapter titles and subtitles are very creative with references to SF books and movies. The subtitles are bit sized and easy to digest. What's missing? I would liked to have seen a discussion on the possibility that we may have been visited before by ET, and that an advanced alien civilization may be purposely avoiding contact with us until we are ready to become a member of the galactic club. No mention of UFO's is made (which in the reviewer's opinion is a good thing). After reading my books, I usually give them to others, or Friends of the Library, but this book will have a permanant home in my library.

The search for life is a complex quest! This book explains and defines the quest and suggests approaches to fulfill our searches with some budgetary discipline and pursue endeavors that have a higher probability of success! Well done!

Scientific approach is refreshing considering the search for alien life (at least in the public realm) seems to have been overtaken by the Roswell/gov't conspiracy/Coast-to-Coast crowd. Would have been interesting to hear the author's views on this part of the equation. Minor quibble...entertaining and very accessible to the layman.

Since the Wall Street Journal seemed to recommend this book, I wanted to give it a try. The book is interesting. The author evaluates five options for discovering "life in the universe". The problem is that he never answers why finding life in the universe outside of the planet earth is important.However, putting that aside, some of the locations that he discovers are interesting - like Enceladus, a moon around Saturn, NASA discovered, through the Cassini unmanned probe, that this moon is covered with a liquid substance many kilometers deep around the planet, below a thick ice cap of many kilometers deep. The question, how do we determine whether there is life on this planet (sorry for the humor, but maybe there are aqua-men below the ice...). We can't dig through that ice. (And, by the way, why should we care?? I hope that someone can answer that question for me because he didn't - maybe it is because they are there, or to justify astro-biologists careers,...)Nothing new regarding the Exoplanets, but reading another version of this was interesting.I guess my issue is that I am not convinced that there is intelligent life other than on Earth (and some could argue not even here). As the title mentioned, all these worlds are yours. Evaluating these locations to see if we can place a base on them makes sense, but other than that - I'm not convinced of the need to spend the money on the research for "life in the universe". Someone - please convince me.I don't recommend this book though because the analysis of these locations, including Titan, are interesting and worth the read if you are interesting in astronomy.

All These Worlds Are Yours: The Scientific Search for Alien Life, by Jon Willis, is structured around a simple proposition: if you had four billion dollars to spend (Willis explains why that number late in the book) to seek out non-terrestrial life, where would it make the most sense to spend it? Willis gives his readers a head start by narrowing their choices at the outset to five "plausible scenarios":Mars (of course)EuropaEnceladusTitanAn exoplanetWillis begins by offering up a relatively quick but sufficiently detailed overview of the conditions that apparently were necessary for life on Earth (liquid water, magnetic field, atmosphere, plate tectonics, a basic shared biochemistry, and a few others), though he is careful to remind us multiple times throughout the book that we should not close our minds to the possibility of other forms of life, though he is realistic in the difficulty of discovering/recognizing such. After covering the famed Miller-Urey experiment (throw together some early-Earth chemicals, add some "lightning," see what happens), he then explores in general terms the same or similar elements in non-Earth terms, discussing for instance the "habitable zone" and the amount of energy from the sun each planet receives (deciding in what may come as a surprise to readers that "there does not appear to be any point or boundary beyond which we can state definitively that the sun is too weak to support photosynthetic life")From there Willis moves into a detailed tour of the four possibilities within our solar system, clearly explaining the the most up-to-date science and recent discoveries regarding each planet/moon, delving as well into the histories and details of the various missions/probes that gave us the science. Among these are Pioneer, Voyager, Cassinni, New Horizons, and others. After going into great detail on the possible conditions for life present on each such as the presence of liquid water (covering as well exactly how such things have been discovered/measured), he runs through just how we might try to learn more about each planet/moon's potential.Willis is no starry-eyed romantic here; his "missions" are wholly grounded in reality, not simply by the laws of physics or the limitations of current technology, but also by fiscal and political reality. Nor does he ever undersell the difficulty of missions such as digging through the surface of another planet/moon or trying to fly through a moon's geysers to take a sample of what is being expelled into space and then return the sample to Earth. He points to both past successes and failures: lost probes, successful sample returns, such as NASA's Stardust and the Japanese Space Agency's Hay Abusa which were able to bring back samples of comets/asteroids). One of the more interesting requirements he names is a joint lab devoted to ensuring any material brought back from space can be safely examined without risk of either contamination or, in a worst-case scenario, an Andromeda Strain-like release into our environment.Finally, Willis leaves our solar system and offers up a nearly infinite set of possible worlds--the billions upon billions of exo-planets that we know exist out there thanks to recent discoveries via Kepler and other mostly space-based telescopes. Missions to these planets are of course impossible--the distances are simply far too great--but Willis explains how we can use better telescopes, some of which are soon to come on-line, to examine the planets' atmospheres, which may give us some markers of life.Willis holds off until the end to give us his own choice, neutrally and methodically laying out the pros and cons of each mission. I won't spoil it; you'll have to read the book to find out. Which I happily recommend doing. Besides the up-to-date science clearly explained (he does a particularly nice job selecting easy to follow analogies to convey concepts) Willis has an engaging voice throughout that even if it sometimes feels like he's trying perhaps a little too hard for a light touch carries you along smoothly through even the most complex points. I also appreciated his focus via the five options and the limited budget. Perhaps the best recommendation for All These Worlds Are Yours (a quote from a Clarke Odyssey novel that also earns Willis some props) is that by the very end, you want to fund all five options. And do so tomorrow. See you on Titan!originally appeared on fantasyliterature.com
