Acerca del autor

Martin Griffiths is an enthusiastic science communicator, writer, and professional astronomer. Over his career he has utilized history, astronomy and science fiction as tools to encourage greater public understanding of science. He is a recipient of the Astrobiology Society of Britain's Public Outreach Award (2008) and the Astronomical League's Outreach Master Award (2010). He also holds the League's Master Observer certificate and has written or contributed to over 100 published science articles for many journals.

He was one of the founder members of NASA's Astrobiology Institute Science Communication Group, which was active between 2003 and 2006; he also managed a multi-million pound ESF program in Astrobiology for adult learners across Wales between 2003 and 2008. Since then he has been involved in promoting adult education, assisting in the development of a new observational astronomy award at the University of Glamorgan and various other projects, including initial consultation on the setup of an observatory in Andalucía, Spain. He is a consultant to the Welsh government through his involvement with the Dark Sky Discovery initiative, enabling public access to dark sky sites in association with Dark Sky Wales, Dark Sky Scotland and Natural England.

Martin is a Fellow of the Royal Astronomical Society and a member of the Astrobiology Society of Britain, the European Society for the History of Science, the British Astronomical Association, the British Science Association, the Webb Deep-Sky Society, the Society for Popular Astronomy, and the Astronomical League.

De la contraportada

Astronomers' Observing Guides provide up-to-date information for amateur astronomers who want to know all about what is it they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments.

Planetary Nebulae and How to Observe Them is intended for amateur astronomers who want to concentrate on one of the most beautiful classes of astronomical objects in the sky. This book will help the observer to see these celestial phenomena using telescopes of various apertures.

As a Sun-like star reaches the end of its life, its hydrogen fuel starts to run out. It collapses until helium nuclei begin nuclear fusion, whereupon the star begins to pulsate, each pulsation throwing off a layer of the star's atmosphere. Eventually the atmosphere has all been ejected as an expanding cloud of gas, the star's core is exposed and ultraviolet photons cause the shell of gas to glow brilliantly - that's planetary nebula.

Topics covered in this book include the astrophysical makeup of planetary nebulae, a history of their discovery, classification and description, telescopes, filters and observing techniques - in short everything anyone would need to observe planetary nebulae.

A special feature of this book is the inclusion of over 100 nebulae in our Milky Way Galaxy personally observed by the author using telescopes of various sizes, enabling readers to make up their own observing program or to follow the authors program. The guide also includes photographs by the author of each object for ease of identification along with their celestial coordinates, magnitudes and other pertinent information.

Here is a volume that should be a welcome addition to any amateur astronomer's personal library, observing course, or school. With it in hand, you can begin sampling right away some of the most captivating objects in the sky.
