Our Universe: An Astronomer’s Guide Hardcover – April 8, 2019

4.6 4.6 out of 5 stars 180 ratings

Jo Dunkley combines her expertise as an astrophysicist with her talents as a teacher and writer in this lively and exceptionally clear introduction to the structure and history of the universe and its enduring mysteries.

Most of us have heard of black holes and supernovas, galaxies and the Big Bang. But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Where are we going?

Jo Dunkley begins in Earth’s neighborhood, explaining the nature of the Solar System, the stars in our night sky, and the Milky Way. She then moves out past nearby galaxies―and back in time―to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life. These visible objects in space sit in a web of dark matter, mysterious stuff we cannot see or yet understand. Dunkley traces the evolution of the universe from the Big Bang fourteen billion years ago, past the birth of the Sun and our planets, to today and beyond. She explains cutting-edge debates about such perplexing phenomena as the accelerating expansion of the universe and the possibility that our universe is only one of many.

Our Universe conveys with authority and grace the thrill of scientific discovery and a contagious enthusiasm for the endless wonders of space-time.

Review

“This luminous guide to the cosmos encapsulates myriad discoveries. Astrophysicist Jo Dunkley swoops from Earth to the observable limits, then explores stellar life cycles, dark matter, cosmic evolution, and the soup-to-nuts history of the Universe. No less a thrill are her accounts of tenth-century Persian astronomer Abd al-Rahman al-Sufi, twentieth- and twenty-first-century researchers Subrahmanyan Chandrasekhar, Jocelyn Bell Burnell and Vera Rubin, and many more.”Nature

“Dunkley takes her readers on a grand tour of space and time, from our nearest planetary neighbors to the edge of the observable Universe…If you feel like refreshing your background knowledge, or are looking for a present for your curious niece or nephew, this little gem certainly won’t disappoint.”
Govert Schilling, BBC Sky at Night

“Combining observational cosmology with a solid theoretical framework, Dunkley’s
Our Universe takes us on a cosmic tour…This is a book any future observational or theoretical astrophysicist would love to have.”Ethan Siegel, Forbes

“Provides a high-level overview of our understanding of the universe that is a good introduction for those unfamiliar with astrophysics.”
Jeff Foust, Space Review

“What with all the commonly appearing stories about space making their way into both the old and new news media these days, an understanding of just what we presently know about what’s ‘out there,’ how we presently think it formed, how it all works together, and where it’s all going is not only fascinating, it also helps to keep things in perspective.”
Johannes E. Riutta, Well-Read Naturalist

“A fascinating, accessible introduction to the universe, covering topics ranging from the Big Bang and the ‘cosmic dawn’ of the first stars to the ongoing search for exoplanets and for dark matter and energy…Dunkley gives readers a commanding view onto the universe and the wonders to be found in it.”
Publishers Weekly

“Jo Dunkley is an internationally acclaimed cosmologist. She is also a fine expositor, and this book splendidly conveys what we’ve learnt about the universe, and the exhilarating progress we can expect in coming decades.”
Martin Rees, Astronomer Royal of Great Britain

“Jo Dunkley takes us on a fantastic journey through our universe―elegantly weaving together history and the latest scientific discoveries. On her way, she subtly restores all the forgotten women scientists to their rightful places in what has been a male-dominated story until now.”
Andrea Wulf, author of The Invention of Nature

“A grand overview of modern cosmology from one of the leaders in the field. Dunkley guides us through astronomical history, at every stage explaining the twists and turns and surprises, right up to the most recent discoveries. Readers will have a real appreciation of the most exciting developments in astrophysics of the last millennium, the last century, and the last year.”
Michael Strauss, Princeton University

“Jo Dunkley is an amiable guide to the universe, but there's no dawdling in this fast-paced tour. This slender volume whisks you from our own blue marble out to the edge of the universe and the beginning of time. Dunkley is especially good at explaining how the whispers from the Big Bang itself tell us about dark matter and dark energy and hint at its explosive origin in cosmic inflation.”
Robert P. Kirshner, Harvard University

“This book is simply superb―beautifully written and very clear. It incorporates all the major recent results, and indicates what might come from telescopes now being built.”
Jocelyn Bell Burnell, University of Oxford

    This is one of the best books I have read on astronomy and astrophysics in a long time (and I read a lot of them). The author went out of her way to cover the universe from beginning to end (so-to-speak) and does a great job of hitting just about every important topic and making it understandable for most anyone with an interest to learn. I have been involved with science and engineering most of my life (having worked for JPL and on the Space Shuttle for NASA) and I often find a need to recommend a good book on astrophysics to someone who doesn't have a lot of math background. Well, I have found it in this book! It would be hard to find a more complete and understandable coverage than this. Vera Rubin, one of the great astronomers mentioned prominently in this book once said "My life has been an interesting voyage. I became an astronomer because I could not imagine living on Earth and not trying to understand how the Universe works." If you really want to understand how this universe works, I would recommend you read this book.

    5.0 out of 5 stars Astronomical
    Reviewed in the United Kingdom on February 4, 2021
    I expected this to be a good read, I was not disappointed it was excellent.
    Jo Dunkley leaves you with a lot to meditate on once you finish each chapter,
    she delves into the nity gritty of some difficult subjects and the last two chapters "the nature of space" and "from start to finish" as engaging as anything I have read on cosmology and specifically dark matter and dark energy.

    She is certainly an excellent communicator of science/astronomy/cosmology.
    Yes there are other books on this subject that go very deep into subjects here but if you want an upto date view of modern astronomy and cosmology this is just the one.

    Hope she opens another in the near future, I for one will read it.

    5.0 out of 5 stars An Excellent Overview of Modern Cosmology
    Reviewed in India on November 19, 2019
    This book, in my humble opinion, is the best available up-to-date overview of modern cosmology. Written in a non-technical and understandable language it can provide answers and ignite amazement to anyone who is interested to know about how we on Earth fit into the larger picture revealed by the strikingly beautiful sky above us.
    The production quality of the Pelican series is excellent, too.
    An insightful read and absolutely recommended.

    The book came today with a cello tape forming a boundary around the frame of the book’s front and back, making it look like it has been tampered with or something. A really odd thing to do.
    The quality of the product itself is fine, but the cello tape raises an eyebrow or two.
