    Plaxco is a strong introduction to astrobiology an undergraduate level textbook that is on the 'science' side of 'popular science' Defining life as a self replicating chemical system capable of evolving such that such that it's offspring might be better suited for survival Plaxco and Gross launch into a history of life on Earth from the Big Bang and the prospects for the future discovery of lifeAs a chemist Plaxco is biased towards chemistry as the most important part of the uestion about life Starting from the fundamental constants of the universe he argues that elemental abundance and the energy reuired for chemical reactions means that life will likely be carbon based and reuire liuid water From that the chemistry gets rather complex The Miller Urey 'primordial sludge' experiments show that amino acids are spontaneously generated from pretty basic elements but doesn't explain how they can link into self reproducing chains There was probably a primitive 'RNA world' which has been entirely erased by the exponentially potent metabolisms and evolutionary capacities of modern bacteria archaea and eukaryotes The sections on the evolution of metabolism and genetics are a slog of chemistry The last bit surveying the potential for life on Mars and gas giant moons is a good run down of contemporary science although this field advances one probe at a time and some observations may be substantially updated since thenThe over all impression is that some kind of micro biological life is probably uite common Detecting it particularly at stellar distances is another matter entirely

    Professor Plaxco was a guest speaker in my Origins class today and he gave an absolutely compelling lecture on astrobiology Sure it was y'know a little on the blue side to hear about the near infinitesimal chances of finding other lifeforms in the universe in addition to the nightmarish thought of self replicating nanomachines that maywill someday destroy us and take over the planet But it was still awesome

    I read this years ago and I liked it a lot While sitting down to write this it occurred to me that it might have been the work of crackpots so I did some investigating Plaxco is a chemistry professor at UCSB so he probably isn't a crank This book is as other reviewers say on the technical side of pop science Still I understood it well enough with little science background beyond AP Chemistry

    This book contains a fair amount of information However I feel that the author held back on particular details of things because it just seems to be missing something; that feeling is not from a lack of understanding on my behalf

    This book was one of many suggested readings for a course I am taking in Astrobiology through corsereaorgI have found one thing about these suggested readings; they are loaded with information Here is the problem with a multitude of information trying to absorb it all There is another problem with many of the suggested readings for courses; most are written to offer the reader the most information in within a few hundred pages They are loaded with footnotes and additional suggested reading; a person could read themselves into oblivion just following the suggested readings The other problem seems to be presentation I have found that some books are much difficult to digest than others; by this I mean most research books make the reader think of being in a lecture the lectures given by those who have made this their life’s work are literally overloaded with information leaving the audience dazed and confused; some are presented by persons who are doing this because this is their job and they just have to do it leaving the audience nodding off and the assimilation of the presented material lost; finally some are presented by people excited by their work and research and eager to share leaving their audience invigorated and longing for This book falls into the third categoryThis book was exciting in a way that is uite unusual for scientific material that of course is my personal view not only did I find myself absorbing the information concerning astrobiology I found myself formulating uestions that were subseuently answered While astrobiology is concerned with life in space it also deals with life on earth ie does life have to follow patterns known from examples on earth with all the galaxies how many planets exist within a habitable zone This book left me excited about my decision to take this coursenow if only all authors could write with this ability my book list would be complete in no time

    This was heavy going in places My chemistry stopped at the age of 15 and I was never any good at it anyway However the authors recognise that the organic and biological chemistry that underpins much of life is indeed complex and they make it as simple as possible for the reader like meThe astrophysics and the atomic physics were easier for me to get on with but of course that's just me it may be that other people have different specialtiesOverall though the authors provide a comprehensive look at the field in a depth which went way beyond the Coursera MOOC that I took recently and it's a book which will repay reading again to extract out of it all that I missed or skipped past the first timeBe warned though this is not easy reading Don't buy this if you're looking for a glib look at UFOs or alien abductions or anything these are not the subjects of the book But if you are looking at possible explanations of how the universe began how planets are formed what conditions are necessary for life to start and some of the possible mechanisms by which it may have begun as well as some philosophical considerations then this is a good place to begin

    This is the Textbook that I chose for my Molecules of Astrobiology topics course that I will be teaching in Spring of 2015 I chose this book because I felt that it would be accessible to most Biology and Chemistry students Since my course will be of a Molecular BiologyBiochemistry course this book offers an introduction to the field that does not reuire a degree in Astronomy or Physics While I wouldn't suggest it to the casual reader it would be a goodread for the armchair scientist

    This was suggested reading for an Astrobiology course I recently had I found this text very easy to follow with my class work and found additional information that wasn't covered from the course I liked the simplicity of this text and it generated some interest in the area of extremophiles I look forward to learning about them esp for an upcoming course on exoplanets

    Very chemistry heavy Interesting but not light reading I recommend it for those who are interested in the chemistry of life possible scientific explanation of the origin of life biological geology early paleontology comparative planetary science Not for everyone but I know for having read it

    It was a bit too technical and scientific for my depth especially on the chemistry aspects of biochemistry but still worthwhile to slog through The RNADNA connections to comets is pretty wild Is this the past or is it the future?
