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!

Astrochemistry as a subject has been rapidly evolving in recent years driven by theory and experimental results. It is a subject that encompasses chemistry, physics, astronomy and biology, and can be thought of as moving from the chemical make up of other atmospheres and space itself, through to the formation of organic life in the universe. It has moved very much from a subject portrayed in science fiction films to hard science. From a teaching point of view, it has the advantage of combining key elements of chemistry with physics and biology in an interesting and stimulating subject, much more appealing to the students than more traditional chemistry subjects. It could become the 'atmospheric chemistry' course of tomorrow.
Astrochemistry is a basic introduction to the chemistry and physics of atmospheres other than Earth's. It is based osecond year chemistry course and assumes some knowledge of physical and organic chemistry along with some basic physics. Little prior knowledge of biology or astrophysics is assumed. Starting with an introduction to the chemical universe, the text covers stellar, meteorite, comet and planetary chemistry, before covering prebiotic chemistry and life in the solar system. Results from the latest research have been included throughout.

The overall structure of the book is plain. Sandwiched between two chapters on the doggedness of Einstein are ten more in approximately chronological order, beginning with an ancient astronomical measurement followed by episodes from the Scientific Revolution (Copernicus through Newton), with accompanying background narratives from ancient science, telling tales revealing some quirky sides of scientists. The format is simple: every chapter constitutes more or less an essay unto itself; furthermore, each is divided into subsections, which are occasionally followed by boxed-in essays on specific peripheral topics. To preserve the integrity of the argument of each chapter while concomitantly avoiding too much duplication, I have cross-referenced relevant material from elsewhere in the book by section number, for example, “see section 2.3” means section 3 of Chapter 2. Accordingly, the book may be read in any order. So, begin browsing, perusing, reading—wherever you wish.
