Galaxy Mapping the Cosmos James Geach

Written by an active researcher in the field, Galaxy: Mapping the Cosmos tells the rich scientific story of galaxy evolution and observation – discoveries of ‘spiral nebulae’, the nature of galaxies and the current ‘World Model’. Astronomer James Geach takes us on a tour of what is currently known and unknown, discussing why the ancient science of astronomy continues to fascinate humanity. Appealing to all readers interested in astronomy and cosmology, and featuring 108 superb colour photographs, Galaxy explores the enigma of our cosmic habitat, chronicling how our home in the Universe came to be.

‘Book of the Month . . . Galaxy is a beautifully illustrated exploration of the Universe beyond the MilkyWay, and the mysteries and wonders of extragalactic astronomy. Geach is ideally placed to be our guide on this journey a researcher in the fast-changing field of galaxy evolution, he displays both breadth and depth of knowledge, happily matched by a talent for engaging, nontechnical prose and an eye for a simile. His work with some of the biggest and most advanced of modern telescopes also provides the vicarious pleasure of some armchair astronomical tourism . . . All in all, the book is an enthralling, detailed and beautiful look at one of the most challenging and exciting areas of modern astronomy, and a great addition to any enthusiasts library.’ — Sky at Night Magazine

‘The night sky is a landscape that has captured the imaginations of millions. Today, were learning more about the Universe than ever, and James Geach is at the forefront of the quest to find out more . . . Geach explains complicated ideas in modern astronomy so that they understandable by anyone with a basic grasp of physics. The book contains dozens of stunning images of galaxies and nebulas, showing the beauty that lurks among the gas and dust of these complex systems . . . an excellent guide to a world many of us never get to see, both on and off this planet.’ — Focus Magazine

‘Astrophysicist Geach goes an order of magnitude further than the usual popular astronomy title those full of breathtaking images, but little in the way of context by giving readers the fascinating stories revealed by those images: how galaxies are created, how they evolve, and what they tell us about our universe. The sheer variety is stunning . . . Gorgeous color photos, coupled with clear and engaging explanations of the science behind them, make this book a winner on every level.’ — Publishers Weekly

‘James Geach is actively researching on one of the most exciting frontiers of todays science: extragalactic astronomy. His book conveys his personal enthusiasm, and offers a clear and highly readable survey of the fields progress and prospects.’ — Professor Martin Rees FRS, Astronomer Royal, Institute of Astronomy, Cambridge

‘Dr Geach brings his personal experience to the fore in describing the latest discoveries in this rapidly developing field of cosmology and galaxy evolution . . . I highly recommend this book for those wanting to share in the excitement of modern astronomy.’ — Prof. Richard Ellis FRS, California Institute of Technology

‘Galaxies are the building blocks of the Universe. But they are dynamic blocks that have changed and evolved throughout the 13 billion years since their seeds sown at the very instant of the Big Bang began to grow. Their trials and tribulations are recounted with great clarity in this short, accessible, yet deep and comprehensve book. What are galaxies made of, why do they have different sizes, luminosities and morphologies, how have they managed to grow gigantic black holes in their midst, all these questions are posed and answered as far as current knowledge permits in an engaging and absorbing way by James Geach. As a practising professional astronomer at the cutting edge of galaxy research, Geach has managed to convey the vibrancy and excitement of research at the very forefront of human knowledge.’ — Prof. Carlos Frenk FRS, Director of the Institute for Computational Cosmology, Durham University

‘you will find out plenty of information on current astronomy, with a surprising amount of depth on some aspects of astronomy and cosmology for an illustrated title. Whether you are interested in the tools used to explore the galaxies or the latest findings, you will find something impressive here.’ — Popular Science
