Rogue Asteroids and Doomsday Comets: The Search for the Million Megaton Menace That Threatens Life on EarthCould a giant asteroid or comet crash into Earth and destroy life as we know it? Many astronomers who once discredited the risks are now convinced. You will be too after reading Duncan Steel's critically acclaimed examination of the evidence of Earth's encounters with killer comets and asteroids. Acclaim for Rogue Asteroids and Doomsday Comets "A chilling and utterly convincing account of a cosmic menace that must not be ignored any longer. This book is a welcome challenge to the scientific prejudice against catastrophism." --Paul Davies, author of The Mind of God "Written in clear prose for the layperson, this gripping report advocates the creation of an international search program to detect, intercept, and divert Earth-menacing asteroids and comets." --Publishers Weekly. "Steel writes clearly and ominously, and he should be listened to." --The Daily Telegraph (London) A selection of the Astronomy Book Club A Library Journal "Best Science Book of the Year" selection |
