    a brief yet informative primer on the search for exoplanets the life of super earths outlines the accelerating uest to discover potentially habitable planets outside of our solar system dimitar sasselov a harvard astronomy professor offers the intriguing backstory of the scientific developments that have led to the discovery of over 600 extrasolar planets sasselov goes into considerable detail in conveying the methods utilized to determine whether a particular star does in fact have orbiting planets including astrometry the doppler effect gravitational lensing spectroscopy and the detection of transiting planets he writes about the formations of super earths presumptive reuirements for life thereon and the myriad reasons why some planets may well be conducive and supportive of life than our own while the entire book is rather fascinating the sparse portions dealing with perovskite a mineral found within the earth's mantle which composes some 40% of our planet's mass high pressure ices vii x xi that can exist at a 1000 degrees kelvin and the future of synthetic biology are of particular note of the 200 billion stars in just our own galaxy there are an estimated 100 million orbiting planets with habitable potential making the prospects for life outside of our solar system uite intriguing considering that there are stars in the universe than there are grains of sand in all the beaches on earth truly boggles one's mind and makes the possibility of there being life on any number of exoplanets seem a mere as yet unproven certainty the life of super earths is an eminently readable work easily accessible to even those with but the faintest scientific education sasselov does a remarkable job of balancing some of the heady scholarship with coherent prose and lucid illustrations sasselov's enthusiasm for his field is rather evident and helps compel the reader to a fully realized comprehension of a truly exhilarating subject

    As a non expert who is nonetheless sufficiently fascinated by science to try to explain uantum mechanics to anyone foolish enough to listen I will admit that I'm not your average reader My knowledge of scientific history and of current discoveries particularly when it comes to space is probably well past your average layperson I say this not to brag but merely to explain why I blew through this book As someone who reads a certain peculiar yet popular bad astronomy blog I freuently smiled to myself every time he mentioned the number of discovered exoplanets as 600 it was in the thousands last I remember with two or three thousand awaiting confirmation If you aren't particularly up to date on scientific news this book will serve as an excellent introduction to trends in both modern astronomy and biology leading us closer to answering the ever important uestion of humanity's alleged uniueness in the universe If you regularly read about these things on the internet there is little here other than some brief anecdotes from scientific history you might not have heard and the light but well written prose that occasionally stretches its wings to wax poetic about some subject or another to great effect There's nothing wrong with a popular science book aimed at people with little interest in science particularly if it argues so poignantly for understanding the beauty of the universe scientifically; I'm just not in that audienceI would recommend this book to my friends who object when I say that scientific understanding doesn't take away the beauty of nature I would not recommend this book to anyone who subscribes to Nature magazine

    While for the most part this book does a great job of describing the types of extrasolar planets discovered and likelihood of our finding life elsewhere I was disappointed in its concluding chapter to the point of feeling irked Why is it that scientists always like to trumpet the idea of synthetic cells or artificial intelligence as the legacy or the future of the extraterrestrial progress of humanity? Why is it that something always must be synthetic created in our own image or of our own understanding of life's mechanism to be worthy of accolade? Why aren't people like Sasselov concerned with finding rival organisms on our own scale in the new other worlds which we know are myriad throughout our galaxy and in all the galaxies beyond as well? Why isn't it exciting to find out exactly how organisms evolve and are extant on other planets than casting some dumb idol of our own making across the skies? That's what I take away from this book anyway In the future I hope to find books theorizing what life on other planets will actually LOOK like than anything as ultimately anthropocentric and anthro chauvinistic such as this one

    If you want to know why we are here this is the book for you Obviously Sasselov does not have a definite answer as to our existence however he takes us on a beautiful journey and builds upon the importance of our existence through it It is a must read for those who are not interested in the science stuff or still believe there are only 9 planets in this universe Through estimates measurements and scenarios Sasselov0 successfully conveys the vastness of our universe and the magic it holds A word of caution For an avid reader of astronomy this book may not appeal to you due to its simplicity and out of date information For me however it did the trick Since putting this book down I have been looking at the stars the sun the sky and all life on earth with awe and wonder


  5. Wendelle Wendelle says:

    lots of info about detection methods like transiting and photometry and about the ualities of super earths thankfully little about the personal lives of the researchers or the regurgitation of the history of astronomy from copernicus and galileo that invasively overpopulate popsci books and dwindle their instructive content


  6. Laura Laura says:

    The true win here is the fascinating discussion of scale why does life as we know it happen on the physical scale that it does? What forces are at work at different scales? Why does this matter in terms of looking for other life? Even cooler is the perspective on the time scale the Universe is actually not that much older than Earth it is on the same scale which is a pretty insane when you think about it A lecturer had once casually thrown out the fact that our Sun was part of the first generation of stars that could have planets capable of supporting life I was completely unable to find anything to back this up until now Sasselov explains why this is likely true Mind stretching seriously I also appreciate him going into some depth as to why size of planet matters as much as location when it comes to habitability the oft mentioned Goldilocks zone is only one small part of the story Be warned the book gets off to a painfully slow start it spends several chapters providing a very basic overview of exoplanet hunting and its history This would not have bothered me except that Sasselov does not seem to know who is audience is he takes multiple sentences to explain what mass is but gives the same amount of text to explaining the entire process of spectroscopy It's like his editor told him he needs to make it accessible to the general public but he had no guidance on what that might mean


  7. Peter Abresch Peter Abresch says:

    This isa great book technical but easy to understand by the layman I had almost no problems following along maybe understood about 98% The author talks of how they discovered new plants in distant solar systems some of which might be super earths up to ten time in size of our earth home and he sets up the case for how life is easily established on them He points out as well that our earth is right on the edge of sustaining life and the super earth because of their greater gravity and mass have a better chance of doing so And the last thing that sort of blew my mind because of time and the size of our earth we could be the first of the intelligent beings Maybe all that yelling out to the stars and getting no response could be because there ain't no one out there


  8. James James says:

    A bit than OK but nothing really special Sasselov writes and explains well enough to keep interest up but he's no Sagan And it's a fascinating subject to be sure A big problem is that this branch of astronomy is so fast moving that even a four year old book is already dated no fault of Sasselov's of course The main problem though is that the subtitle is misleading this is about the hunt for alien worlds and life and how that will affect our view of human existence but artificial cells barely rate a mention and the last part of the subtitle is pure hyperbole The life of Super Earths The Hunt for Life Beyond the Solar System would be a far accurate and neutral title If that is what you're looking for in a book though it is a worthwhile read


  9. Mishehu Mishehu says:

    Book's subtitle is a bit misleading Emphasis is on the search for other worlds capable of generatingsustaining life and which may already be doinghave done so Very little to do with artificial cells And even less on the potentially revolutionizing impact of both areas of investigation on life on earth other than the possibility that exoplanets may one day provide harbor for terrestrial life when our sun powers down Nonetheless it's a fascinating read Bit prosaic in the telling at first but picks up momentum as it moves along Heady stuff and a terrific intro to one very cutting edge area of contemporary science

    Good basic introduction to what we currently know about extrasolar planets what the planetary conditions are that could support life and the basic biologicalchemical conditions needed to sustain life
