Около 15 миллиардов лет назад ослепительный взрыв, Большой взрыв, дал рождение Вселенной, пространству и времени. С тех пор беспрерывно продолжается эволюция от простого к сложному. Огромный космический ковер появился из микроскопической пустоты. И теперь в фантастическом балете участвуют сотни миллиардов галактик, каждая из которых населена сотнями миллиардов звезд. Затерянная в дальнем уголке нашей галактики, которая называется Млечный Путь, одна звезда, наше Солнце, щедро делится своим теплом с 9 планетами, которые ее окружают. На одной из них, Земле, с позволения Солнца и поддерживается жизнь. Рассказывая о расширении и становлении Вселенной, астрофизик Тринх Ксуан Тхуан напоминает нам, что человек является лишь частицей звездной пыли. Снимки, сделанные радиотелескопами и космическими телескопами, показывают нам красоту космического пространства. Всего 170 иллюстраций.

This book features essential coverage of all major aspects of Earth's solar system, from every feature of the major planets to their satellites, small bodies, interplanetary phenomena, and cosmological context. Designed to meet the needs of both general readers and students, this completely revised and updated edition covers 180 major topics on Earth's solar system as it is understood from the latest perspectives. For this new edition, 58 new topics have been added and every essay has been thoroughly expanded, from the text through bibliographies, to bring it up to date in view of the many interplanetary missions that have expanded our knowledge of the solar system - from Pioneer and Voyager through the missions of Galileo, Cassini-Huygens, the Hubble Space Telescope, and the latest Mars probes as of 2009. Scope and coverage: No reference dedicated to the solar system is this detailed or complete and up to date. Coverage is presented in an A-Z format - from 'Archaeoastronomy' and 'Asteroids' through 'Venus' Volcanoes' and 'White and Black Dwarfs' - and is supplemented by more than two hundred photos. For those wishing instant access to essays grouped by planetary system, a Category Index appears in the front of every volume. Essays fall into one or more of the following categories: the Cosmological Context, Earth, the Jovian System, Life in the Solar System, Mars, Mercury, Natural Planetary Satellites, Neptune, Planets and Planetology, the Saturnian System, Scientific Methods, Small Bodies, the Solar System as a Whole, the Stellar Context, the Sun, Uranus, and Venus. Organization and format: Essays range in length from three to seven pages and offer a complete overview of the topic as well as an assessment of knowledge gained, methods of study, or applications. Each essay begins with standard, ready-reference information, including the title of the essay, the category (or categories) in which the essay falls, and a summary of the importance of the topic and the current state of our knowledge. The essay is then broken down into several subsections. An 'Overview' section, generally the longest subsection in the essay, details basic information about the subject and discusses the main facts about the topic. 'Knowledge Gained/Methods of Study/Applications' details how the topic is investigated, what scientific knowledge we have accumulated, or the uses of the knowledge we have gained. 'Context' addresses the topic from the larger perspective of the history of solar-system science and its relevance for humankind. 'Further Reading' is an annotated selection of the most important print resources for further study. Lastly, 'See Also' lists cross-references to other essays in The Solar System covering related topics. Special features: the front matter of each volume includes a Complete List of Contents and a Category Index. The set is heavily illustrated, with over 300 photos. At the end of volume three, users will find a general bibliography, a list of web resources, a comprehensive glossary, and a full subject index. This title contains 3 Volumes; 1,056 Pages; 180 Essays, 58 New; 'See Also' Cross-References; Complete List of Contents; Category Index; Glossary; Bibliography; Web Sites; and Subject Index.

The spectacular collision of Comet Shoemaker-Levy 9 with Jupiter in July 1994 was a unique event in the history of astronomy. With a year's advance warning, astronomers and planetary scientists around the world were able to coordinate an observing campaign to track the event in unprecedented detail. A year after the event, a workshop at the Space Telescope Science Institute provided the first opportunity for them to bring together their observations and foster a new understanding of the impact. In this book, the editors present fifteen invited reviews from authors selected as international leaders in the study of the impact and its aftermath. They have edited and arranged the chapters to provide a thorough and comprehensive overview of our knowledge of the event. While our understanding of the impact will evolve with future work, this book provides a solid foundation for new insights.

The metronomic variations of the Earth-Moon system and of theEarth-Sun orbital patterns produce gravitational and temperatureeffects that alter the physical environment on the Earth’ssurface. These give an interpenetrating effect of forcing cyclesranging from twice-daily tides, day-night alternations, varioustidal patterns and the annual solar pattern. All of these havebeen used palaeontologically to give precision to short-termage determination in the past. It is cycles of the Milankovitch band that are showing promiseof enabling new practical timescales to be established for partsof the geological record. These depend on changes in the Earth-Sundistance and changes in the tilt of the Earth’s axis withrespect to the Earth’s orbit round the Sun. There is increasingevidence that small-scale sedimentary rhythmic couplets mayrepresent the effect of such changes. The disentangling of theinterpenetrating cycles to produce an orbital forcing timescaleis an exciting problem and challenge for palaeobiology and sedimentology.These should enable numerical dates to be given to bio- andchronostratigraphical timescales and eventually enable manyEarth processes to be analysed in real time. The papers in this volume represent major new developments insedimentological, paIaeontological, geochemical and stratigraphicalresearch being undertaken in this field.

The study of cataclysmic variables - interacting binary stars containing a white dwarf accreting from an orbiting companion - is undergoing an exciting renaissance, as it embraces observations at all wavelengths. Cataclysmic variables allow, in particular, the direct and detailed study of equilibrium and non-equilibrium accretion discs; in turn these developments also help in our understanding of X-ray binaries, black holes and active galactic nuclei. This timely volume provides the first comprehensive survey of cataclysmic variable stars, integrating theory and observation into a single, synthesised text. An introductory chapter gives the historical background of studies of cataclysmic variables. The author then goes on to give an up-to-date review of both the observations (at all wavelengths, and over all time-scales), the theories, the models of the structures and accretion processes believed to be involved. A very detailed bibliography is also provided to guide the reader to pertinent primary literature.

Found throughout the universe, variable stars are fascinating objects to observe. Their brightness changes over time and they can easily be seen with even the most basic equipment. David Levy explains how to begin electronic (or CCD) observing, as well as how to observe variable stars through a small telescope or binoculars. Featuring a section on Southern hemisphere stars, this book covers various types of objects that can be observed by amateur astronomers, including more exotic phenomena like gamma ray bursts, blazars, and polars. It will motivate anyone with even a basic interest in astronomy to begin observing variable stars.
David H. Levy is one of the most successful comet hunters in history. He has discovered twenty-one, eight of them using a telescope in his own backyard. With Eugene and Carolyn Shoemaker at the Palomar Observatory in California, Levy discovered Shoemaker-Levy 9, the comet that collided with Jupiter in 1994, and is currently involved with the Jarnac Comet Survey, based at the Jarnac Observatory in Vail, Arizona.

This book provides a comprehensive introduction to space weather: the physical phenomena that result from the interaction of the sun and the planets. Physics of the Space Environment explores the basic processes in the sun, in the interplanetary medium, in the near-Earth space, and down into the atmosphere. The first part of the book summarizes fundamental elements of transport theory relevant for the atmosphere, ionosphere and the magnetosphere, then applies this theory to physical phenomena in the space environment. The book emphasizes both the fundamental physical processes and basic concepts and methods. This book is unique in its balanced treatment of space plasma and aeronomical phenomena. Students and researchers with a basic math and physics background will find this book invaluable in the study of phenomena in the space environment.
