Описание:

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.

Описание: In this concise monograph, Sir Henry Englefield (1752-1822) guides the reader through the computation of cometary orbits. First published in 1793, it represented one of the few such manuals available in English, and draws on the work of Newton, Pingre, Laplace, and Englefield`s own correspondence with William Herschel.

Описание: This volume considers the role comets may have played in the origins and evolution of life. It is particularly relevant in light of recent investigations of Halley`s comet, of new insights into organic synthesis in meteorites and comets, and of new results of numerical simulations of cometary orbits and impacts on Earth.

Описание: Originally published in 1953, this book first sets out some observational facts about comets, then the greater part of the book accounts for their origin and explains how comet tails are formed. The text contains 34 photographs of celebrated comets, including eight of Halley`s comet. A comet index is also provided.
