The interdisciplinary field of Astrobiology constitutes a joint arena where provocative discoveries are coalescing concerning, e.g. the prevalence of exoplanets, the diversity and hardiness of life, and its increasingly likely chances for its emergence. Biologists, astrophysicists, biochemists, geoscientists and space scientists share this exciting mission of revealing the origin and commonality of life in the Universe. The members of the different disciplines are used to their own terminology and technical language. In the interdisciplinary environment many terms either have redundant meanings or are completely unfamiliar to members of other disciplines. The Encyclopedia of Astrobiology serves as the key to a common understanding. Each new or experienced researcher and graduate student in adjacent fields of astrobiology will appreciate this reference work in the quest to understand the big picture. The carefully selected group of active researchers contributing to this work and the expert field editors intend for their contributions, from an internationally comprehensive perspective, to accelerate the interdisciplinary advance of astrobiology.

Volume packed full of information that illuminates key astronomical concepts along side the history and legends surrounding the stars and planets.

Selected by 50 notable astronomers from the major sub-fields of the discipline, the articles assembled in this special AAS Centennial collection are accompanied by commentary that provides the scientific-historical context essential to comprehending each article's original impact. Many commentators were contemporaries of the original authors and provide first-person accounts of papers published in the journals—and the earliest reactions they evoked. Arranged in chronological order of publication, these classic papers include works by Subrahmanyan Chandrasekhar, George E. Hale, Fred Hoyle, Edwin Hubble, A.A. Michelson, Henry Norris Russell, Arthur Achuster, Harlow Shapley, and others. Together the articles and commentaries provide a historical window into twentieth-century astronomy and how the results were achieved.

Taking notes on astronomical observations is a valuable tool and time-honored tradition for professional and amateur astronomers alike. We hope that this journal serves you well in recording your astronomical observations and sharing your experiences with others. This 8x10" journal includes 100 blank observational logs to enhance your skygazing experience. Designed by Camp Galaxy, the elegant log format included here allows you to record details about the object or objects being observed and the site and conditions at the time of observation. Five full pages for notes and reflections are also included at the end of the journal. Paperback-bound with a charming and beautiful cover, this journal is sure to be a lasting record of your unique observations. This lovely astronomy log also makes a wonderful gift for the star gazer in your life.

An introduction to practical astrometry, dealing with the determination of positions, motions, distances and dimensions of celestial bodies ranging from quasars to artificial satellites. For this 2nd edition, the release of the Hipparcos and Tycho catalogs, the rise in CCD astrometry and the adoption of a new celestial reference frame by the IAU led to a significant modification of the text. And, especially, the outlook for astrometry has been completely rewritten.

With information and scale as central themes, this comprehensive survey explains how to handle real problems in astronomical data analysis using a modern arsenal of powerful techniques. It treats those innovative methods of image, signal, and data processing that are proving to be both effective and widely relevant. The authors are leaders in this rapidly developing field and draw upon decades of experience. They have been playing leading roles in international projects such as the Virtual Observatory and the Grid. The book addresses not only students and professional astronomers and astrophysicists, but also serious amateur astronomers and specialists in earth observation, medical imaging, and data mining. The coverage includes chapters or appendices on: detection and filtering; image compression; multichannel, multiscale, and catalog data analytical methods; wavelets transforms, Picard iteration, and software tools. This second edition of Starck and Murtagh's highly appreciated reference again deals with topics that are at or beyond the state of the art. It presents material which is more algorithmically oriented than most alternatives and broaches new areas like ridgelet and curvelet transforms. Throughout the book various additions and updates have been made.

The study of extraterrestrial magnetic fields is a relatively new one, confirmation of the existance of the first such field (that of our Sun) having come a s late as 1908. In the past 30 years a great ammount of knowledge has been accumulated on Cosmic Magnetism, which has turned out to be a truly fascinating topic for study. Percy Seymour's book is the first to deal with the topic in a non-mathematical way, and he offers a fine introduction to his subject. The first three chapters consolidate our knowledge on magnetism in general and the magnetic field of the Earth, as well as discussing the reasons for studying astronomy and cosmic magnetism in particular. The remainder of the book is devoted to the main areas of cosmic magnetism - solar, plantetary and interplanetary fields, fields in stars and pulsars, fields of the milky way and fields in other galaxies. Cosmic Magnetism in an ideal book for sixth-formers and undergraduates studying physics or astronomy and will also appeal to amateur astronomers. as previous work on this topic has been 'hidden' in specialised academic journals.
