Beschreibungen

This book is intended for amateur astronomers who are readers of Sky & Telescope magazine or similar astronomy periodicals – or are at least at the same level of knowledge and enthusiasm. Supernovae represent the most violent stellar explosions in the universe. This 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 the book describes the best strategies for discovering and observing them. Moreover, it contains detailed information about the probable physics of supernovae, a subject which even today is imperfectly understood.
This book is a unique guide to supernova facts, and it is also an observing/discovery guide, all in one package. It is the only book about supernovae that explains to amateur astronomers what they are, and how to observe and discover them.
Supernova explosions, which mark the deaths of massive stars or of white dwarf stars in binary systems,are unbelievably violent events. Despite occurring in gal- ies many millions of light-years away,amateur telescopes can reveal these colossal explosions,and even discover them. In the past 25 years,the amateur astronomer’s contribution to supernova research has been staggering. Visual variable star observers with access to large-aperture amateur telescopes have contributed a steady stream of magnitude estimates of the brightest and closest supernovae. In addition, with the increasing availability of robotic telescopes and CCD techn- ogy, more and more amateurs are discovering supernovae from their backyards. Worldwide, there have been more than 400 supernovae discovered by amateur astronomers using amateur telescopes. Supernova research has never been so important. Recent professional measurements of the most distant Type Ia sup- novae have revealed the staggering and unexpected discovery that the acceleration of the Universe is actually increasing! This,in turn,has led to a new phrase, dark energy,entering the astronomical vocabulary; a mysterious force,in opposition to gravity, driving the accelerated expansion. Although amateurs cannot study the farthest supernovae,their discovery and measurement of the closer examples helps to re?ne the science that is the hottest topic in cosmology today; that is,pinning down the history of the Universe and how much mass and energy exists within it today. As always, amateur astronomers are making a valuable contribution, and, hopefully, this book might inspire a few more to monitor and discover new supernovae. Martin Mobberley Suffolk, U. K.

Supernovae mark the deaths of massive stars or of white dwarfs in binary systems, and are unbelievably violent events. Even when they occur in galaxies millions of light years away they can be within the reach of amateur astronomers’ telescopes.
More than 400 supernovae have already been discovered by amateurs.
Supernovae and How to Observe Them is a mine of information for all levels of amateur astronomer, from relative beginners to experienced observers. Whether you are interested in the supernova physics, observing supernovae and supernova remnants, measuring their spectra or even discovering new supernovae yourself, this book provides all the information you need.
Contains all the currently-known facts on supernovae, in a single book
Explains in clear, readable language what supernovae are, and how we currently believe the physics of supernovae operate
Contains detailed galaxy images for readers to begin their own search for new supernovae
Describes how the world’s top supernova hunters conduct their searches
The only book about supernovae – the most violent stellar events in the universe – that explains to amateur astronomers what they are, and how to observe and discover them
