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.

Что бы вы подумали, если бы вас стали уверять, будто наша Земля вертится вовсе не в ту сторону, а то и вообще неподвижно висит в космическом пространстве?.. Или история земных цивилизаций таковой вовсе не является, а всего лишь — досужий вымысел?.. Абсурд! Однако существует удивительная гипотеза наших соотечественников, которая очень долго и старательно замалчивалась. Книга предлагает вам ознакомиться с иным взглядом на мировую историю и не торопиться с резкими выводами: ведь вполне возможно, что события, описанные в древних мифах, если и случились, то совсем не там и не тогда, как нас с вами уверяют.

Studies of stellar formation in galaxies have a profound impact on our understanding of the present and the early universe. The book describes complex physical processes involved in the creation of stars and during their young lives. It illustrates how these processes reveal themselves from radio wavelengths to high energy X-rays and gamma -rays, with special reference towards high energy signatures. Several sections devoted to key analysis techniques demonstrate how modern research in this field is pursued.

Целью монографии известного физика и математика Роджера Пенроуза является поиск фундаментальных принципов, положенных в основу нашего мироздания и управляющих протекающими в нем процессами. Можно сказать, что книга эта, в сущности, посвящена отношениям между математикой и физикой, тому взаимодействию между двумя дисциплинами, которое играет далеко не последнюю роль в стремлении двигаться дальше в поисках лучшей теории для описания Вселенной. Специалист из любой области найдет в этой фундаментальной монографии что-нибудь для себя полезное; возможно, точка зрения автора на некоторые предметы отличается (а порой и весьма радикально) от общепринятой, но именно это позволит посмотреть на актуальные проблемы современной науки с разных сторон и приблизиться к истине. Несомненный интерес представляет его мнение относительно ряда современных теоретических построений, таких, например, как теория суперсимметрии, космология расширяющейся Вселенной, гипотезы о природе Большого взрыва и черных дыр, теория струн или М-теория, переменные цикла в квантовой гравитации, теория твисторов, да и собственно фундаментальные принципы квантовой теории.

Various kinds of masks obscure our view of our galaxy, the Milky Way, as well as of other galaxies. Masks of interstellar dust affect our measurements within galaxies, on scales ranging from individual supernovae to the galaxies themselves. The “mass mask” (our inability to image mass rather than light) gives astronomers a very incomplete picture of the size and structure of galaxies themselves, because we cannot image the dark matter which provides most of the galactic mass. Another mass is the “dynamical mask”: as galaxies form, much dynamical information is lost in the birthing process. A new thrust in research is to retrieve such information by means of chemical tagging. About 50 astronomers flew into Namibia in April 2010, to celebrate the 70th birthday of Professor K.C. Freeman, Fellow of the Royal Society. At age 70, Freeman, a father of dark matter in galaxies, continues to be one of planet’s most highly cited astronomers. The current volume affords readers a unique perspective on galaxies by probing the thoughts of some of the greatest astronomers of our age. Contributions focus on galaxies from within our Local Group to those in our high redshift Universe. Approximately 40 in-depth review and contributed papers are contained in the volume, each written by an expert in the field. Two unusual features of the current volume include the “Star Country” of the San people of southern Africa as well as the introduction into astronomy of “The Treachery of Images” by the Belgian surrealist artist René Magritte. “Everything we see hides another thing, we always want to see what is hidden by what we see”, said Magritte. These words resonate the theme of the current volume “Galaxies and their Masks”, which is written at a level to be appreciated by both specialist and doctoral student alike.

Over the past ten years, the discovery of extrasolar planets has opened a new field of astronomy, and this area of research is rapidly growing, from both the observational and theoretical point of view. The presence of many giant exoplanets in the close vicinity of their star shows that these newly discovered planetary systems are very different from the solar system. New theoretical models are being developed in order to understand their formation scenarios, and new observational methods are being implemented to increase the sensitivity of exoplanet detections. In the present book, the authors address the question of planetary systems from all aspects. Starting from the facts (the detection of more than 300 extraterrestrial planets), they first describe the various methods used for these discoveries and propose a synthetic analysis of their global properties. They then consider the observations of young stars and circumstellar disks and address the case of the solar system as a specific example, different from the newly discovered systems. Then the study of planetary systems and of exoplanets is presented from a more theoretical point of view. The book ends with an outlook to future astronomical projects, and a description of the search for life on exoplanets. This book addresses students and researchers who wish to better understand this newly expanding field of research.

This book introduces the reader to the field of nuclear astrophysics, i.e. the acquisition and reading of measurements on unstable isotopes in different parts of the universe. The authors explain the role of radioactivities in astrophysics, discuss specific sources of cosmic isotopes and in which special regions they can be observed. More specifically, the authors address stars of different types, stellar explosions which terminate stellar evolutions, and other explosions triggered by mass transfers and instabilities in binary stars. They also address nuclear reactions and transport processes in interstellar space, in the contexts of cosmic rays and of chemical evolution. A special chapter is dedicated to the solar system which even provides material samples. The book also contains a description of key tools which astrophysicists employ in those particular studies and a glossary of key terms in astronomy with radioactivities.

Star clusters are some of the most beautiful objects in the night sky and are prime targets for observational astronomers as well as astrophotographers. Using some of the newer technologies and larger and more powerful telescopes available today to amateur astronomers, many more of these dazzling groupings of stars can now be located and viewed throughout the year. In this field guide that will help you to decide what to look for and where to look for it, as well as what equipment to use, you will find what you need, whether you are a beginner in the field or an experienced observer. So on the next clear night, take your book and your binoculars or telescope and maybe your camera outside and see what new wonders can be revealed to you. You won’t be disappointed!

Have you ever seen a shooting star? What you really saw was a meteor! A meteor is actually a chunk of metallic or stony matter - called a meteoroid - that enters the earth's atmosphere from outer space. A comet, on the other hand, is a lump of ice and dust that periodically comes into the center of the solar system from somewhere in its outer reaches. Learn more about meteors and comets in this lively and informative book!
