The formation of galaxies is one of the greatest puzzles in astronomy, the solution is shrouded in the depths of space and time, but has profound implications for the universe we observe today. The book discusses the beginnings of the process from cosmological observations and calculations, considers the broad features of galaxies that we need to explain and what we know of their later history. The author compares the competing theories for galaxy formation and considers the progress expected from new generations of powerful telescopes both on earth and in space. In this second edition the author has retained the observationally-based approach of the first edition, a feature which was particularly well-reviewed: Writing in Nature, Carlton Baugh noted in February 2003 that “It is refreshing, in a market dominated by theorists, to come across a book on galaxy formation written from an observational perspective. The Road to Galaxy Formation should prove to be a handy primer on observations for graduate students, advanced undergraduates and theorists who feel too shy to visit a telescope”.
The New Scientist wrote in March 2003: “William Keel delicately balances observational evidence against today's relevant theoretical possibilities”.
And Sepehr Arbabi-Bidgoli wrote in Astronomische Nachrichten that “Reading this book I often felt like sitting in an exciting and entertaining lecture given by an astronomer who knows the subject and knows how to present it to the audience”.
A Bibliography at the end of each chapter contains a resumé of books, selected research papers and Web resources providing guidance to further reading

Many lights and other objects in the sky go unrecognised, or at least are little understood by those observing them. Such things range from the commonplace like rainbows and meteors, to the distinctly unusual like the green flash and ball lightning. And there is still a residuum of objects that remain unidentified by the watcher – classed generally as ‘UFOs’, a description which today has connotations of the mysterious, even of extraterrestrial visitors.
The first part of this book is an identification guide, very much like the "plant identifier" sections found in a good gardening or botany book. It allows quick (and structured) identification of known aerial phenomena, whether at night or during the day. The objects thus found are referenced to the second part of the book.
The second part gives a full description, physical explanation, and where relevant notes on observing and photographing the various phenomena. Some will need optical aids such as binoculars or telescopes, but the main thrust of the book is identification and explanation rather than imaging.
The final chapter approaches UFOs from a scientific standpoint, particularly the way in which human perception and often preconception affects the outcome. It does however finish with a short section on "extraterrestrial UFOs", emphasising the burden of proof aspect and touching on the scientific theories of life on other worlds and the improbability of visitors.

Solar-type activity over the whole range of the electromagnetic spectrum is a phenomenon inherent in the majority of low- and moderate-mass main sequence stars. In this monograph observational results are summarized in a systematic and comprehensive fashion. The analysis of the various manifestations of such stellar activity leads to the identification of these phenomena with macroscopic non-linear processes in a magnetized plasma. Comparative study of flare stars and the Sun has become increasingly fruitful and is presently an active field of research involving stellar and solar physicists, experts in plasma physics and high-energy astrophysicists. This book will provide them with both an introduction and overview of observational results from the first optical photometry and spectroscopy, from the satellite telescopes International Ultraviolet Explorer to Hubble Space Telescope, XMM-Newton and Chandra, as well as with the present physical interpretation of solar-type activity in main sequence stars. Gershberg's 40-year career studying UV Cet type stars and related objects enables him to provide readers with expert insight into the characteristics of such stars in both the quiescent state and during flares and the reliability of the data over the electromagnetic spectrum and wide temporal scales.

Энциклопедия насекомых - уникальное, не имеющее себе равных издание, которое будет интересно и детям, и взрослым. Известные британские энтомологи объездили весь мир, чтобы специально для этой книги собрать тысячи любопытных и малоизвестных фактов о всех видах насекомых, включая самые редкие и экзотические. Лучшие художники Англии несколько лет работали над иллюстрациями к этому изданию, стараясь добиться эффекта полного проникновения в мир насекомых - объемный, яркий, наполненный звуками и запахами. И имэто блестяще удалось! Путешествуя по страницам этой великолепной книги, вы узнаете не только о том, кто в мире насекомых самый быстрый, самый умный, самый ядовитый, самый сильный и самый агрессивный, но также и то, где насекомые живут, что они едят и с кем предпочитают дружить. Только, пожалуйста, не пугайтесь, если на одной из страниц вдруг наткнетесь на какого-нибудь ужасного монстра, - это всего лишь книга, завораживающая и немного пугающая, но невероятно интересная!
