Can you spot the Big Dipper in the night sky? Or Orion's Belt? Or Cassiopeia? Even in cities, and without the aid of a telescope, these are a few of the easier constellations to find. In fact, a great deal can be seen in the night sky with the naked eye - if you know what you're looking for. Night Sky presents 200 colour photographs of stunning nocturnal vistas all visible to the naked eye. From the majesty of the Northern Lights (Aurora borealis) as seen from Norway or Canada, and the Southern Lights (Aurora australis) as seen from Australia, to seeing the clarity of the Milky Way over an Italian forest, from witnessing a lunar eclipse in Indonesia to charting the course of the International Space Station across the Indian night, and from seeing a Geminid meteor shower in New Mexico to recognizing the Great Bear (Ursa Major) constellation over New England, the book is a feast of nocturnal delights. Where necessary, additional inset photographs indicate the formation of a constellation. Presented in a handy, pocket-sized landscape format - take it out at night when you're stargazing - and featuring 200 outstanding colour photographs supported by fascinating captions, Night Sky is a stunning collection of images.

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.

The two most fascinating questions about extraterrestrial life are where it is found and what it is like. In particular, from our Earth-based vantage point, we are keen to know where the closest life to us is, and how similar it might be to life on our home planet. This book deals with both of these key issues. It considers possible homes for life, with a focus on Earth-like exoplanets. And it examines the possibility that life elsewhere might be similar to life here, due to the existence of parallel environments, which may result in Darwinian selection producing parallel trees of life between one planet and another. Understanding Life in the Universe provides an engaging and myth-busting overview for any reader interested in the existence and nature of extraterrestrial life, and the realistic possibility of discovering credible evidence for it in the near future.
