Synopses & Reviews
For the past twelve billion years, galaxies have governed the Universe, bringing form to the firmament, light to the void. Each one a giant system of as many as hundreds of billions of stars, the galaxies are the building blocks of the cosmos, and through new data from modern telescopes--including the Hubble Space Telescope--we are discovering dizzying new facts about how they formed, how they evolve, and what they are made of. This book acquaints readers with these facts and findings--and with what they can tell us about the lives of galaxies over cosmic time, from their emergence shortly after the Hot Big Bang to their ongoing gyrations and transmutations.
Waller, a professor of astronomy, teams with Hodge, editor-in-chief of Astronomical Journal, to present recent advances due largely to the advent of massive earthbound and spaceborne telescopes. In fact, these instruments now allow astronomers to detect 'galaxies so distant that we are seeing them shortly after their emergence from the din of the Big Bang,' the authors write. Science News
Some galaxies erupt in starbursts; most contain giant black holes at their cores, each containing several million or billion times as much mass as our sun. William Waller and Paul Hodge give us a magisterial tour of these galaxies and their environment in space. Jay Pasachoff
Orienting us with an insider's tour of the Milky Way, Waller and Hodge offer a guide to the latest news from the cosmic frontier, bringing form to the building blocks of the cosmos, the galaxies.
Includes bibliographical references (p. 275-282) and index.
Orienting readers with an insider's tour of their cosmic home, and Milky Way, the authors then take readers on a spectacular journey, inviting them to probe the structures and dynamics of the galaxies in this basic guide to the latest news from the cosmic frontier. Illustrations.
acquaints readers with these facts and findings--and with what they can tell us about the lives of galaxies over cosmic time, from their emergence shortly after the Hot Big Bang to their ongoing gyrations and transmutations.
Orienting us with an insider's tour of our cosmic home, the Milky Way, William Waller and Paul Hodge then take us on a spectacular journey, inviting us to probe the exquisite structures and dynamics of the giant spiral and elliptical galaxies, to witness colliding and erupting galaxies, and to pay our respects to the most powerful galaxies of all--the quasars. A basic guide to the latest news from the cosmic frontier--about the black holes in the centers of galaxies, about the way in which some galaxies cannibalize each other, about the vast distances between galaxies, and about the remarkable new evidence regarding dark energy and the cosmic expansion--this book gives us a firm foundation for exploring the more speculative fringes of our current understanding.
