From the publisher’s promo: One of the liveliest scientific controversies in years focuses on the possible existence of a small, dim star, "Nemesis," that causes comet showers in our solar system every 26 million years. Any number of comets striking Earth would cause a "nuclear winter" and mass extinctions, such as that of the dinosaurs 65 million years ago. As astronomer Donald Goldsmith unsnarls the conflicting explanations for periodic extinction, he takes the reader on a tour of iridium deposits in Italian cliffs; the Oort cloud—a remote swirl of a trillion comets; the Siberian site of the mysterious Tunguska explosion of 1908; and nearby regions of the Milky Way that astronomers have just started to comb for the "death star." Also considered are explanations that compete with the Nemesis theory: the "galactic oscillation" hypothesis, which ties extinctions on Earth to the, path of the sun as it bobs around the Milky Way; and the concept of "Planet X"—an undiscovered member of our solar system that may lurk beyond Pluto. Donald Goldsmith adroitly develops the latest findings in a variety of fields: astronomy, astrophysics, geology, paleontology, exobiology, and others. The result is a book that links the basic principles of these disciplines in new ways, showing clearly how the thoughts of scientists from around the globe can combine to yield novel results. If valid, the new ideas about periodic extinction may change the way we think about biological evolution, nuclear Armageddon, the structure of the solar system, and the possibility of life on other planets.” Biographical Note: Dr. Goldsmith is a Visiting Lecturer at the University of California, Berkeley—the city where he lives. He was a consultant for the "Cosmos" TV series, and winner of first prize in the 1983 Griffith Observatory essay contest for popular writing on astronomy. His many include The Evolving Universe, Cosmic Horizons, and The Search for Life in the Universe.
