After destroying the Muudia Portal passage and saving their home worlds, the newly assembled V-357 crew are faced with many dangers from inside and outside their ship. As they search for the true passage home, the crew struggles to sustain their just mission despite becoming the most-wanted criminals in a new dimension. Along the way, the science given them before their journey is proven to be faulty. The hope of ever seeing their homes again becomes fractured at a foundational level. Through creativity and friends in unexpected places, the V-357 crew press forward; only because they can't go back. Their harrowing journey draws them ever-closer to a mysterious being more powerful than they've ever experienced or imagine!

A complete and in-depth review of exoplanet research, covering the discovery methods, physics and theoretical background.

Retief is an officer of the distinguished Corps Diplomatique Terrestrienne, a supra-national organization devoted to keeping the peace - or more accurately, to maintaining a state of tension short of armed conflict. Retief is not exactly in the mainstream of current Galactic diplomacy, as expounded by such giants of the C.D.T. as Crodfoller, Hidebinder, Straphanger, and his own immediate superior, Magnan. Deviously sincere, uncompromisingly venal, fearlessly cowardly, these great, dedicated public servants will seem curiously familiar as they strive to keep the peace seven hundred years in the future. But when Retief's on the scene things have a way of coming right in the end...

Since it was first published in 1987, Galactic Dynamics has become the most widely used advanced textbook on the structure and dynamics of galaxies and one of the most cited references in astrophysics. Now, in this extensively revised and updated edition, James Binney and Scott Tremaine describe the dramatic recent advances in this subject, making Galactic Dynamics the most authoritative introduction to galactic astrophysics available to advanced undergraduate students, graduate students, and researchers. Every part of the book has been thoroughly overhauled, and many sections have been completely rewritten. Many new topics are covered, including N-body simulation methods, black holes in stellar systems, linear stability and response theory, and galaxy formation in the cosmological context. Binney and Tremaine, two of the world's leading astrophysicists, use the tools of theoretical physics to describe how galaxies and other stellar systems work, succinctly and lucidly explaining theoretical principles and their applications to observational phenomena. They provide readers with an understanding of stellar dynamics at the level needed to reach the frontiers of the subject. This new edition of the classic text is the definitive introduction to the field. ? A complete revision and update of one of the most cited references in astrophysics Provides a comprehensive description of the dynamical structure and evolution of galaxies and other stellar systems Serves as both a graduate textbook and a resource for researchers Includes 20 color illustrations, 205 figures, and more than 200 problems Covers the gravitational N-body problem, hierarchical galaxy formation, galaxy mergers, dark matter, spiral structure, numerical simulations, orbits and chaos, equilibrium and stability of stellar systems, evolution of binary stars and star clusters, and much more Companion volume to Galactic Astronomy, the definitive book on the phenomenology of galaxies and star clusters

Battered and broken, the V-357 gets an upgrade. In return, the crew are given three trials that must be completed before they can return home. The missions will test every ounce of faith they have in their vessel, and in each other. When everything looks impossible, they're forced to look inward to find the courage. Some answers are found in science--others require faith.

The present set of chapters by members of the staff of the National Radio Astronomy Observatory deals with the basic fields of research concerned with radio astronomy outside the solar system. The emphasis in this volume is on the type of data available and its interpretation. Basic theory is considered only where absolutely necessary, and little discussion of receivers or techniques is entered into in most of the chapters. The book is intended to take over where most textbooks on radio astronomy leave off, that is, in the discussion of what is actually known from the research done. In addition there is a chapter on the technical aspects of inter ferometry and aperture synthesis, since so much of modern radio astronomy depends, and will depend in an ever increasing manner, on such tools. The editors want to stress that the chapters were not necessarily expected to be compre hensive reviews of any of the fields being covered, but rather, overall outlines which the in dividual authors feIt would be suitable for graduate students and interested workers in other fields. As a result, the lists of references are not complete. This only refiects the preferences of the individual authors and not the relative merit of those references incIuded or omitted.

In the centennial year, 1985-86, of Harlow Shapley's birth, the study of globular clusters was no less important to the development of astronomy than in 1915, when Shapley first noted their concentration on the sky. By 1917 Shapley had used the properties of the system of globular clusters to complete the Copernican revolution and locate the solar system, and its Earth-bound observers, far from the center of the Galaxy and the globular cluster distribution. Seven decades later, in the year of these proceedings, globular cluster research and the study of the system of globular clusters in our own and distant galaxies is undergoing a renaissance of activity. The introduction of new observational tools, particularly CCD imagers and digital spectrographs, as well as powerful theoretical methods have transformed the study of globular clusters into one of the main line areas of modern astrophysics. Thus it seemed particularly appropriate to one of us, when considering how the Harvard College Observatory might mark the Shapley centennial, to propose and plan for an IAU Symposium on Globular Cluster Systems in Galaxies. Planning for the Shapley Symposium, as it came to be called, was even more drawn out than the preparation of this volume. The Symposium was originally proposed to the IAU Secretariat in time for it to be held in August, 1985, so that it might occur in the centennial (calendar) year.
