Astrophysical jets are spectacular displays of gas or dust ejected from a range of cosmic bodies; they are seemingly ubiquitous on scales from comets to black holes. This volume reviews our understanding of jet processes and provides a modern guide to their observation and the role they play in many long-standing problems in astrophysics. It covers the major discoveries in gamma-ray bursts, solar and stellar jets and cometary jets. Specific physical processes for all classes of jet are illustrated and discussed in depth, as a backdrop to explaining spectacular jet images. Current jet models raise as many issues as they solve, so the final chapter looks at the new questions to be answered. Written at an entry level for postgraduate students, this volume incorporates introductions to all the governing physics, providing a comprehensive and insightful guide to the study of jets for researchers across all branches of astrophysics.

Some 400 years after the first known patent application for a telescope by Hans Lipperhey, The Astronomy Revolution: 400 Years of Exploring the Cosmos surveys the effects of this instrument and explores the questions that have arisen out of scientific research in astronomy and cosmology. Inspired by the international New Vision 400 conference held in Beijing in October 2008, this interdisciplinary volume brings together expanded and updated contributions from 26 esteemed conference speakers and invited others. Looking beyond questions of science to the role of moral responsibility in human civilizations, the book offers the unique vantage points of contributions from both Eastern and Western cultures.

Planetary Nebulae and How to Observe Them is for amateur astronomers who want to go beyond the Messier objects, concentrating on one of the most beautiful classes of astronomical objects in the sky. Planetary nebulae are not visible to the naked eye, but they are a fascinating group of telescope objects. This guide enables a user equipped with an average-sized amateur telescope to get the best out of observing them. Topics covered include their astrophysical make-up, history of their discovery, classification and description, telescopes to use, filters, and observing techniques - in short everything anyone would need to know to successfully observe planetary nebulae. The book describes the various forms these astronomical objects can take and explains why they are favorite targets for amateur observers. Descriptions of over 100 nebulae personally observed by the author using telescopes of various sizes are included in the book. Readers can create their own observing program or follow the list of these captivating objects, many of which are found within our own Milky Way Galaxy.

This volume summarizes the recent results of the exploration of Venus, Mars and Titan in the field of space plasma physics. These are the only non-magnetic solar system bodies having dense atmospheres. A number of space missions investigated these objects; the past and the current missions are put in context with modern theoretical descriptions. The strength of the book is the comparison of the similarities and differences in the plasma interaction of Venus, Mars and Titan; such comparisons have not yet been published. This volume is aimed at graduate students and researchers working in planetary science and space physics. Previously published in Space Science Reviews journal,

This title is a comprehensive set of visual descriptions of deep-sky objects visible from the northern hemisphere. It is a record of the most extensive and systematic visual survey of the sky ever done in modern times. 3,000 deep-sky objects are listed with short descriptions of the visual appearance in the author's powerful binocular telescope. Objects in the book are organized by position for easy identification of unknown targets. Full indexes by catalog numbers and names allow searches for specific objects.

Information collected by satellites recently sent by the USA, the European Space Agency, Japan, Germany, the United Kingdom, and Russia to monitor the Sun has changed our knowledge and understanding of the Sun, particularly its effect on Earth. This book presents these findings in a way that will be welcomed by amateur astronomers, students, educators and anyone interested in the Sun. Enhanced by many colour photographs, the book combines newly acquired scientific understanding with detailed descriptions of features visible on the Sun’s surface and in its atmosphere. In the past, observing the Sun has been left to academics with specialised instruments, since solar observation has been unsafe because of the risk of eye damage. This book explains how amateur astronomers can safely observe the various solar phenomena using special hydrogen-alpha telescopes that are not too expensive. Amateurs can now make a positive contribution to science by monitoring the Sun as professionals do. Amateurs can also access the solar images taken by satellites via the internet. This book helps readers interpret and understand what these images are showing about the Sun, including the latest 3D images. Solar observers will enjoy comparing their own solar telescope observations with those produced by space probes such as SDO, SOHO, Hinode and STEREO, and further enjoy learning about transits, eclipses, and space weather and how the Sun compares to other stars in the universe. The main purpose of this book is to present some of the fascinating solar phenomena in their full splendor to readers through a variety of illustrations, photographs and easy to understand text.

For over ten years, the dark side of the universe has been headline news. Detailed studies of the rotation of spiral galaxies, and 'mirages' created by clusters of galaxies bending the light from very remote objects, have convinced astronomers of the presence of large quantities of dark (unseen) matter in the cosmos. The most striking fact is that they seem to compromise about 95% of the matter/energy content of the universe. As for ordinary matter, although we are immersed in a sea of dark particles, including primordial neutrinos and photons from fossil cosmological radiation, both we and our environment are made of ordinary, 'baryonic' matter. Authors Mazure and Le Brun present the inventory of matter, baryonic and exotic, and investigating the nature and fate of matter's twin, anti-matter. They show how technological progress has been a result of basic research, in tandem with the evolution of new ideas, and how the combined effect of these advances might help lift the cosmic veil.

Edward Emerson Barnard's Photographic Atlas of Selected Regions of the Milky Way was originally published in two volumes in 1927. Together these volumes contained a wealth of information, including photographic plates of the most interesting portions of the Milky Way, descriptive text, charts, and data. Only 700 copies were printed, making the original edition a collector's item. Reproduced in print for the first time, this edition combines both volumes of Barnard's Atlas. It directly replicates Barnard's text, and contains high resolution images of the original photographic plates and charts, reordered so that they can be seen together. It also includes a biography of Barnard and his work, a Foreword and Addendum by Gerald Orin Dobek describing the importance of the Atlas and additions to this volume, and a pull-out section with a mosaic of all 50 plates combined in a single panorama.

The Sun, which is our own star at the center of the Solar System, gives rise to all life on Earth and is the driver of photosynthesis in plants and the source of all food and energy for living things. As seen with the naked eye, the Sun appears as a static and quiet yellow disk in the sky. However, it is a stormy and ever-changing star that contributes much more than light and heat.

Fathoming the boundlessness of space and the universe, we are immediately filled with curiosity about our own origins and wonder about the objects, life forms, and matter that populate the cosmos. Through the observations and work of astronomers over time, we have slowly been able to reduce the number of unknowns and develop explanations or theories for some of the celestial objects and phenomena we see. This space-traveling survey recounts some of the major discovery milestones in the field of astronomy and examines the tools and techniques currently used by astronomers to study the universe.
