Rejuvenating the Sun and Avoiding Other Global Catastrophes

About this book

This book investigates the idea that the distant future evolution of our Sun might be `controlled' (literally, asteroengineered) so that it maintains its present-day energy output rather than becoming a highly luminous and bloated red giant star - a process that, if allowed to develop, will destroy all life on Earth. The text outlines how asteroengineering might work in principle and it describes what the future solar system could look like. It also addresses the idea of asteroengineering as a galaxy-wide imperative, explaining why the Earth has never been visited by extraterrestrial travellers in the past.

Biography

Associate professor of astronomy, and Head of the Astronomy Department at Campion College, The University of Regina. My main research interests during the past decade have focused on the smaller objects within the solar system (comets, asteroids and meteoroids), but concomitant to this I have continued to perform research related to the structure and evolution of stars (the area of my doctoral studies). The book being proposed here is partly based upon a series of research papers that I have published over the years and on material used in a solar system studies class. The topic of asteroengineering was recently the focus of an 'opinion article' I wrote for the May 2006 issue of Astronomy Now magazine, and an editorial piece in the May 2006 issue of Smithsonian Air and Space magazine.
