Book Synopsis Incoming Asteroid! by : Duncan Lunan
Download or read book Incoming Asteroid! written by Duncan Lunan and published by Springer Science & Business Media. This book was released on 2013-10-17 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘Incoming Asteroid!’ is based on a project within ASTRA (the Association in Scotland to Research into Astronautics) to provide scientific answers to the question – what would we do if we knew there was going to be an asteroid impact in ten years’ time or less? Clearly there are many things humanity can do nothing about, for example an unseen object traveling towards us so fast that we have no time to prepare, or an object so large it may be unstoppable. A realistic hazard model was decided upon, and the scenario developed from that: an incoming object about 1 kilometer in diameter, in an orbit ranging from the outer rim of the Asteroid Belt to within that of Earth’s. Three basic possibilities are considered in this book. The first is the deflection of the asteroid, using remote probes along with a number of possible technologies to change the asteroid’s course. Second is the attempt of a manned mission, in order to plant a propulsion system on the asteroid to push it into a different orbit. Third is the nuclear option, a last-ditch attempt to break up and then disperse the asteroid using nuclear weapons. (A rather impractical combination of these second and third options were used as the plot of the popular 1998 Bruce Willis feature film, Armageddon.) Although the cost of developing the technology needed to protect the Earth would be substantial, there would certainly be spin-off benefits. These could eventually result in practical small-scale atomic energy sources, new propulsion systems that could make extraterrestrial mining within the solar system a possibility, and other as-yet unforeseen benefits. And finally, Incoming Asteroid! considers the political implications - how governments across the world should best react to the threat with a view to minimizing loss of life, and in the weeks running up to the possible impact, preventing panic in the population.
Book Synopsis Instrumentation and Research Programmes for Small Telescopes by : J.B. Hearnshaw
Download or read book Instrumentation and Research Programmes for Small Telescopes written by J.B. Hearnshaw and published by Springer. This book was released on 1986-09-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the proceedings of IAU Symposium No. 118 on "Instrumentation. and Research Programmes for Small Telescopes", where small telescopes were defined as those ground-based instruments with apertures less than 1.5m. The scientific goal of the symposium was to emphasise research programmes which were more suited to smaller tele scopes, on which frequent regular observations can be made. A wide variety of topics on instrumentation, photometry, spectroscopy and polarimetry of objects in the solar system to extragalactic systems were discussed. Each of the four scientific days of the symposium comprised a number of invited review papers, contributed oral papers and discussion sessions devoted purely to the large number (~4) of poster papers. An introductory paper on the research potential of small telescopes sets the scene for the symposium. The proceedings have then been divided into three sections. Section I: Telescopes and instrumentation; Section II: Photometric research programmes; Section III: Spectroscopic research programmes. The diversity of topics within each of these sections indicated the extent to which small telescopes have (and can) contribute greatly to astronomical research. Dr J.A. Graham's summary of the symposium, which illustrates the opportunities available with small telescopes, concludes these proceedings. As in all symposia, the importance of the discussion following each paper was realised. The discussion was recorded on tape (and wherever possible on questions and answer sheets), transcribed and then edited.
Book Synopsis Planets, Stars and Nebulae by : Tom Gehrels
Download or read book Planets, Stars and Nebulae written by Tom Gehrels and published by University of Arizona Press. This book was released on 1974-03 with total page 1160 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The polarization study of celestial objects is a valuable part of optical astronomy, and the author has done exceptionally well in bringing to gether contributions treating all aspects of the polarimetry field. . . . The first section contains a fine introduction and an excellent and definitive history of the subject. . . . The volume is well illustrated. . . . Highly recommended."ÑChoice "The high quality of this book is clearly due to strict editorial attention to each paper and the discussions. Gehrel's book will surely stand for many years as the fundamental reference source for polarization studies in astronomy as well as in atmospheric physics."ÑJournal of the Assoc. of Lunar and Planetary Observers
