“Telescopes and Techniques” has proved itself in its first edition, having become probably one of the most widely used astronomy texts, both for numerate amateur astronomers and for astronomy and astrophysics undergraduates. The first and second editions of the book were widely used as set texts for introductory practical astronomy courses in many universities. This book guides the reader through the mathematics, physics and practical techniques needed to use telescopes (from small amateur models to the larger instruments installed in many colleges) and to observe objects in the sky. Mathematics to around Advanced Placement standard (US) or A level (UK) is assumed, although High School D...
Astrophysical Techniques provides a comprehensive and clearly understandable account of the instruments and techniques used in astronomy and astrophysics. Drawing together an ever-diverging array of observational techniques, using the common thread of a detection-imaging-ancillary instruments pattern, Dr Kitchin has provided us with a unified view of astrophysical investigation. The author's fully illustrated text starts from first principles and explains each method up to the point at which you can begin practical work with the equipment and even start designing it. Exercises with answers are used to reinforce the ideas presented in each chapter. There is also an extensive bibliography to e...
The birth of a completely new branch of observational astronomy is a rare and exciting occurrence. For a long time, our theories about gravitational waves—proposed by Albert Einstein and others more than a hundred years ago—could never be fully proven, since we lacked the proper technology to do it. That all changed when, on September 14, 2015, instruments at the LIGO Observatory detected gravitational waves for the first time. This book explores the nature of gravitational waves—what they are, where they come from, why they are so significant and why nobody could prove they existed before now. Written in plain language and interspersed with additional explanatory tutorials, it will appeal to lay readers, science enthusiasts, physical science students, amateur astronomers and to professional scientists and astronomers.
Long used in undergraduate and introductory graduate courses, Astrophysical Techniques, Seventh Edition provides an accessible yet comprehensive account of the innovate instruments, detectors, and techniques employed in astronomy and astrophysics. Emphasizing the underlying unity of all astronomical observations, this popular textbook provides a coherent state-of-the-art account of the instruments and techniques used in current astronomy and astrophysics. Fully updated throughout, this seventh edition builds upon the sixth edition, covering improved techniques and cutting-edge methods in the field, as well as other exciting new developments in gravitational waves, dark matter and energy, the...
The modern aspiring astronomer is faced with a bewil dering choice of commercially produced telescopes, including all the designs considered in the preceding chapter. Yet only four decades ago the choice for a small telescope would have been between just a refrac tor and a Newtonian reflector. That change has come about because of the enormous interest that has grown in astronomy since the start of the space age and with the mind-boggling discoveries of the past 30 or 40 years. Except for some of the very small instruments which are unfortunately often heavily promoted in general mail order catalogues, camera shops and the like, the optical quality of these commercially pro duced telescopes is almost uniformly excellent. Although one product may be slightly better for some types of observation, or more suited to the personal cir cumstances of the observer, than another, most of them will provide excellent observing opportunities. The same general praise cannot be applied, however, to the mountings with which many of these telescopes are provided, and those problems are covered in Chapter 6.
A concise introduction, Optical Astronomical Spectroscopy appeals to the newcomer of astronomical spectroscopy and assumes no previous specialist knowledge. Beginning from the physical background of spectroscopy with a clear explanation of energy levels and spectroscopic notation, the book proceeds to introduce the main techniques of optical spectroscopy and the range of instrumentation that is available. With clarity and directness, it then describes the applications of spectroscopy in modern astronomy, such as the solar system, stars, nebulae, the interstellar medium, and galaxies, giving an immediate appeal to beginners.
Exoplanets: Finding, Exploring, and Understanding Alien Worlds probes the basis for possible answers to the fundamentals questions asked about these planets orbiting stars other than our Sun. This book examines what such planets might be like, where they are, and how we find them. Until around ten years ago, the only planets that we knew about were within the Solar System. The first genuine planet beyond the confines of the Solar System was discovered only 1988. Since then another 350 or so exoplanets have been detected by various methods, and most of these haven been found in the last ten years. Although many more exoplanets discoveries may be expected to occur even as this book is being re...
This essential and highly-illustrated guide is for anyone taking their first steps in observational astronomy. It shows what you can expect to see, helping you get the most from your equipment. This unique book gives amateurs the guidance and assurance they need to become more proficient observers.
"l hope that people all around the world never forget what a wonderful thing it is to lie on your back and look up at the stars" Pete Seeger What is the fascination that constellations hold for people? There are probably as many different answers to that question as there are people. For many, though, the constella tions are the stepping-off point into the fabulous, mind-bending discoveries and concepts of modern astronomy. For others it is their long and intriguing history that beckons. For some people the constellations provide the means for navigation and orientation over the surface of the Earth, and of course there are the millions who place some faith in horo scopes. But for most peopl...
Journeys to the Ends of the Universe presents a tour through the universe from the big bang onward. The book explores the limits of knowledge where scientific fact overtakes and merges with the wilder speculations of science fiction. The beginnings of galaxies, stars, planets, and even life itself are related back to the raveled turmoil of the first few seconds and years of life in the cosmos. The journey continues past the ultimate fate of the solar system to probe the nature of supernovae. The future of galaxies, clusters of galaxies, super-clusters of clusters of galaxies, and so on leads toward the finale, where the author provides some bizarre musings of physicists and astronomers, suggesting possible destinies for the universe stretching its present age billions of times into the future.
