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.
