YA-- This highly readable account of the initial observation of supernova SN1987A tempts readers to understand abstract and difficult concepts of astronomy, as well as to appreciate supernovae as the origins of all chemical elements, and therefore, all life on any planet including ours. Nonscientists are sure to appreciate the account of how the observations of SN1987A continue to provide astronomers with new data to support and deny existing theories about the life and death of stars. Goldsmith explains different kinds of measurements done of different particles as they arrive here after 160,000 light years' journey; neutrinos are counted in obscure waterfilled chambers deep underground while gamma rays are counted by satellites. He also recounts some history of astronomy as he details other supernovae that have been observed on Earth in 1054, 1572, and 1604 by Tycho Brahe and Kepler, among others. This book could be added to summer reading lists with nonfiction sections, and it provides good research material for chemistry, physics, and astronomy students.
