Naked-eye comets are far from uncommon. As a rough average, one appears every 18 months or thereabouts, and it is not very unusual to see more than two in a single year. The record so far seems to have been 2004, with a total of five comets visible without optical aid. But 2006, 1970, and 1911 were not far behind with a total of four apiece. Yet, the majority of these pass unnoticed by the general public. Most simply look like fuzzy stars with tails that are either faint or below the naked-eye threshold. The ‘classical’ comet – a bright star-like object with a long flowing tail – is a sight that graces our skies about once per decade, on average. These ‘great comets’ are surely among the most beautiful objects that we can see in the heavens, and it is no wonder that they created such fear in earlier times. Just what makes a comet ‘‘great’’ is not easy to define. It is neither just about brightness nor only a matter of size. Some comets can sport prodigiously long tails and yet not be regarded as great. Others can become very bright, but hardly anyone other than a handful of enthusiastic astronomers will ever see them. Much depends on their separation from the Sun, the intensity of the tail, and so forth.

In these days of computers and CCD cameras, visual comet observers can still contribute scientifically useful data with the help of this handy reference for use in the field. Comets are one of the principal areas for productive pro-amateur collaboration in astronomy, but finding comets requires a different approach than the observing of more predictable targets. Principally directed toward amateur astronomers who prefer visual observing or who are interested in discovering a new comet or visually monitoring the behavior of known comets, it includes all the advice needed to thrive as a comet observer. After presenting a brief overview of the nature of comets and how we came to the modern understanding of comets, this book details the various types of observations that can usefully be carried out at the eyepiece of a telescope. Subjects range from how to search for new comets to visually estimating the brightness of comets and the length and orientation of tails, in addition to what to look for in comet heads and tails. Details are also given of 20 periodic comets, predicted to return between the years 2017 and 2027, that are expected to become suitable targets for visual observing, in addition to information on a famous comet potentially visible each year and subject to great outbursts of brightness.

Spectacular and mysterious objects that come and go in the night sky, comets have dwelt in our popular culture for untold ages. As remnants from the formation of the Solar system, they are objects of key scientific research and space missions. As one of nature's most potent and dramatic dangers, they pose a threat to our safety--and yet they were the origin of our oceans and perhaps even life itself. This beautifully illustrated book tells the story of the biggest and most awe-inspiring of all comets: those that have earned the title "Great." Robert Burnham focuses on the Great comets Hyakutake in 1996 and Hale-Bopp in 1997, which gripped attention worldwide because, for many, they were the first comets ever seen. He places these two recent comets in the context of their predecessors from past ages, among them the famous Comet Halley. Great Comets explains the exciting new discoveries that have come from these magnificent objects and profiles the spaceprobes to comets due for launch in the next few years. The book even takes a peek behind Hollywood's science-fiction fantasies to assess the real risks humanity faces from potential impacts of both comets and asteroids. For everyone interested in astronomy, this exciting book reveals the secrets of the Great Comets and provides essential tools for keeping up to date with comet discoveries in the future. Robert Burnham has been an amateur astronomer since the mid-1950s. He has been a senior editor of Astronomy magazine (1986-88) and is the author of many books and CD-ROMS, including Comet Hale-Bopp: Find and Enjoy the Great Comet and Comet Explorer.

This book concentrates on some of the odd aspects of comets and asteroids. Strange behavior of comets, such as outbursts and schisms, and how asteroids can temporally act as comets are discussed, together with the possible threat of Centaurs-class objects like the Taurid complex. Recent years have seen the distinction between comets and asteroids become less prominent. Comets in "asteroid" orbits and vice versa have become almost commonplace and a clearer view of the role of small bodies in the formation of the Solar System and their effect on Earth has become apparent. Seargent covers this development in detail by including new data and information from space probes.

Ice and Fire: Great Comets to Come was written because a special celestial event climaxes towards the end of 2013 – the arrival, fresh from the Oort Cloud, of Comet C/2012 S1 (ISON). By all predictions – even the most pessimistic ones – this comet is set to be one of, perhaps the most, dazzling comet seen in modern history and has the astronomical world buzzing with anticipation. Skywatchers have already been primed for C/2012 (ISON) earlier in 2013 with the apparition of another naked-eye comet, C/2011 L4 (PanSTARRS), and following C/2012 S1 (ISON) there is the prospect of 2012 K1 (PanSTARRS) reaching naked eye visibility in August 2014. Future bright cometary prospects are also discussed, taking into account the latest predictions. Examining the origin and nature of comets using examples of great comets from the past, this book sets the scene for the arrival of Comet C/2012 S1 and those following it over the next few years in the inner Solar System. Skywatchers and amateur astronomers can learn how to follow, observe and record comets. There is also a guide on how to keep abreast of the latest cometary discoveries and how to use a variety of reputable sources, including publications, websites, programs and apps to visualize and plan observations. The role of the amateur in cometary discovery also is featured, as well as details on how professional astronomers plan to get the most ‘science’ out of cometary apparitions, how and why professionals go about discovering comets, and upcoming plans to visit comets with space probes (and later, perhaps, human visits). Illustrations provide historic images of comets, images from space probes and images of the latest bright comets. Orbital plots and easy-to-follow sky charts are also included. This book is a unique guide that sets the scene by giving a comprehensive history of comets and examples of great comets throughout history and informs the reader about the nature and origins of this spectacular occurence. Expectations are fully covered by explaining not only what the regular person can expect to see, but how amateur astronomers can plan observations and what steps the professionals are taking to ‘get the most science’ from this exciting event.

This book will take the story of astronomy on from where Allan Chapman left it in Stargazers, and bring it almost up to date, with the developments and discoveries of the last three centuries. He covers the big names - Halley, Hooke, Herschel, Hubble and Hoyle; and includes the women who pushed astronomy forward, from Caroline Herschel to the Victorian women astronomers. He includes the big discoveries and the huge ideas, from the Milky War, to the Big Bang, the mighty atom, and the question of life on other planets. And he brings in the contributions made in the US, culminating in their race with the USSR to get a man on the moon, before turning to the explosion of interest in astronomy that was pioneered by Sir Patrick Moore and The Sky at Night.
