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.This is a heavily revised and completely updated version of Hodge’s Galaxies, which won an Association of American Publishers PROSE Award for Best Science Book of the Year in 1986.

This book offers an intimate guide to the Milky Way, taking readers on a grand tour of our home Galaxy's structure, genesis, and evolution, based on the latest astronomical findings. In engaging language, it tells how the Milky Way congealed from blobs of gas and dark matter into a spinning starry abode brimming with diverse planetary systems--some of which may be hosting myriad life forms and perhaps even other technologically communicative species. William Waller vividly describes the Milky Way as it appears in the night sky, acquainting readers with its key components and telling the history of our changing galactic perceptions. The ancients believed the Milky Way was a home for the gods. Today we know it is but one galaxy among billions of others in the observable universe. Within the Milky Way, ground-based and space-borne telescopes have revealed that our Solar System is not alone. Hundreds of other planetary systems share our tiny part of the vast Galaxy. We reside within a galactic ecosystem that is driven by the theatrics of the most massive stars as they blaze through their brilliant lives and dramatic deaths.Similarly effervescent ecosystems of hot young stars and fluorescing nebulae delineate the graceful spiral arms in our Galaxy's swirling disk. Beyond the disk, the spheroidal halo hosts the ponderous--and still mysterious--dark matter that outweighs everything else. Another dark mystery lurks deep in the heart of the Milky Way, where a supermassive black hole has produced bizarre phenomena seen at multiple wavelengths. Waller makes the case that our very existence is inextricably linked to the Galaxy that spawned us. Through this book, readers can become well-informed galactic "insiders"--ready to imagine humanity's next steps as fully engaged citizens of the Milky Way.

To study astronomy is to consider the most wondrous phenomena on the grandest of scales – the universe and all it contains. Beginning with our earliest explorations of the night sky, William Waller takes us on an enthralling journey through the Milky Way and far, far beyond. He combines science and history to show how our understanding of everything from black holes to the structure of the universe has evolved over time, illuminating past discoveries and offering contemporary insights into the cosmic histories of stars, planets and galaxies. Whether object of study or curiosity, the universe – and all it contains – is tantalisingly introduced here.

It is not hyperbole to state that galactic ecosystems have spawned pretty much everything that we hold dear – including ourselves. These nebular nurseries have incubated all the stars, planetary systems, and many of the complex molecules known to humanity. From there, the myriad of planets in orbit around their hosting stars have further refined the organic matter into even more complex biochemicals. On the surface of one particularly moist planet, life took hold, and evolutionary processes led to you and me collectively pondering the wonders of galactic ecosystems via this book.Given the seminal role of galactic ecosystems in hosting this tale of being and becoming, it is necessary to consider the full sweep of cosmic scales. In this book, we will explore atomic nuclei and their alchemic transmutations within stars, the assembly of atoms into molecules within cryogenic clouds, and prospects for building up the macromolecules necessary for life as we know it. On a much larger scale, we will discover protostars and protoplanetary disks inside molecular cloud cores a few light-years in size, their hosting molecular clouds tens of light-years across, giant molecular clouds and ionized nebulae hundreds of light-years in extent, and finally entire starburst galaxies spanning thousands of light-years.Along the way, we will gain an appreciation for the most massive, powerful, and short-lived stars as they transform their natal environments via their intense radiation, winds, and explosive deaths. Without the elemental beneficence of these stars, rocky planets, water, and life itself would be impossible.Through reading this book, you will obtain a better understanding of your birthright as a “child of the cosmos.” As with all lifeforms on Earth, and likely myriad of other lifeforms on worlds yet to be explored, this sense of communion pervades the cosmos, made visceral through the awesome creativity of galactic ecosystems.
