From supernovae and gamma-ray bursts to the accelerating Universe, this is an exploration of the intellectual threads that lead to some of the most exciting ideas in modern astrophysics and cosmology. This fully updated second edition incorporates new material on binary stars, black holes, gamma-ray bursts, worm-holes, quantum gravity and string theory. It covers the origins of stars and their evolution, the mechanisms responsible for supernovae, and their progeny, neutron stars and black holes. It examines the theoretical ideas behind black holes and their manifestation in observational astronomy and presents neutron stars in all their variety known today.
This book also covers the physics of the twentieth century, discussing quantum theory and Einstein's gravity, how these two theories collide, and the prospects for their reconciliation in the twenty-first century. This will be essential reading for undergraduate students in astronomy and astrophysics, and an excellent, accessible introduction for a wider audience.

This book is intended for amateur astronomers who are readers of Sky and Telescope magazine or similar astronomy periodicals – or are at least at the same level of knowledge and enthusiasm. Supernovae, the subject of this book, represent the most violent stellar explosions in the universe. It is a unique guide to supernova facts, and it is also an observing/discovery guide, all in one package. Supernovae are often discovered by amateur astronomers, and Martin Mobberley describes the best strategies for discovering and observing them. Moreover, Supernovae and How to Observe Them contains detailed information about the probable physics of supernovae, a subject which even today is imperfectly understood. Here is a book that is essential reading for any amateur astronomer who is interested in discovering, observing, or learning about supernovae.

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.

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.

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

For the experienced amateur astronomer who is wondering if there is something useful, valuable, and permanent that can be done with his or her observational skills, the answer is, "Yes, you can!" This is the book for the experienced amateur astronomer who is ready to take a new step in his or her astronomical journey. Unfortunately, there is no modern text that points curious amateur astronomers to the research possibilities that are open to them. At the 2006 meeting of the Society for Astronomical Sciences, quite a few participants agreed that the lack of such a text was a serious gap in the astronomical book market, and that this gap is impeding their efforts to encourage more amateur astronomers to get involved in research collaborations. This book will fill that gap, and enable more amateur astronomers to add research-type studies to their pursuit of the hobby.
Written by an astronomer who is well known amongst the amateur and professional community for the skill and quality of his work, this book describes a wide range of research areas where amateurs are gathering new scientific data that is utilized by professional astronomers. For each research area, the book provides a concise explanation of the purpose and value of the amateurs’ observations, a description of the equipment that is needed, specific observing procedures, complete data reduction instructions, and an explanation of how, and where, to submit results so that they will be available to the professional users.

Most amateur astronomers, because they live in or near cities, have to carry out their observing from relatively light-polluted sites. It is possible to reduce the effects of a poor location by the use of CCD imaging, but many observers prefer to look at astronomical objects rather than photograph them. Skill, observing techniques, and modern technology - such as image intensifiers - can now be used to astonishing effect to observe the night sky in real-time. Illustrating the book with images and some of his own superb drawings, Antony Cooke explains how to observe some of the most spectacular objects from less than perfect observing sites.

The book will, in jargon-free blow-by-blow terms, describe how to create the best astronomical images you can with the digital camera equipment at your disposal. It will explain the steps we go through to extract results from the raw-and-dirty original imagery, and then transform them into high quality pictures that you could hang on your wall.
The advent of CCDs, and more recently inexpensive webcams, has led to a much greater proportion of amateur astronomers becoming involved in digital imaging. The low price of the new Meade Deep Sky Imager - $299 (2005) – suggests that within a few years a simple digital camera will become a standard accessory for any telescope.
There are as yet few books available on this aspect of amateur astronomy. This situation is likely to change in the next few years and there are going to be lots of people out there asking questions like "Flat field? What does that mean?", and trying to work out how to get the best out of their webcam, CCD or Digital SLR. They will also be wondering what is the best software to use.
To summarise; this is a book that tells practical astronomers (and that includes some but not all professionals) what is needed to get from standing in the dark with a telescope and a camera, to showing your spouse, local society friends or even supervisor the astonishing images that can be obtained with simple equipment but the right software and knowledge of how to use it.

n the last few years, cheap webcams have revolutionized amateur astronomy by providing a very inexpensive alternative to purpose-made astronomical CCD cameras, which use refrigerated imaging chips and are thus extremely expensive. Webcams are capable of more advanced work than 'normal' digital cameras because their simple construction makes it easy to remove the webcam's lens, allowing it to be interfaced directly to a telescope. Using a webcam is not difficult but most amateur astronomers who have tried to do this do not achieve the finest results, despite the webcam's potential. There are numerous imaging and image processing tricks and techniques, and all of them are needed to get the best results.Along with webcam technology has come simple-to-use image processing and enhancement using a PC: the most powerful technique is, 'stacking' in which the best images (out of hundreds) are selected and summed automatically to provide startlingly good results."Lunar and Planetary Webcam Userв_Ts Guide" de-mystifies the jargon of webcams and computer processing, and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. He looks at each observing target separately, describing and explaining all specialised techniques in context.Glance through the images in this book to see just how much you can в_" easily в_" achieve by using a webcam with your telescope!
