Asteroids: A History (Smithsonian History of Aviation & Spaceflight Series),Used
Delivery time: 8-12 business days (International)
Asteroids suggest images of a catastrophic impact with Earth, triggering infernos, tidal waves, famine, and death but these scenarios have obscured the larger story of how asteroids have been discovered and studied. During the past two centuries, the quest for knowledge about asteroids has involved eminent scientists and amateur astronomers, patient research and sudden intuition, advanced technology and the simplest of telescopes, newspaper headlines and Cold War secrets. Today, researchers have named and identified the mineral composition of these objects. They range in size from 33 feet to 580 miles wide and most are found in a belt between the orbits of Mars and Jupiter. Covering all aspects of asteroid investigation, Curtis Peebles shows how ideas about the orbiting boulders have evolved. He describes how such phenomena as the Moon's craters and dinosaur extinction were gradually, and by some scientists grudgingly, accepted as the results of asteroid impacts. He tells how a band of icy asteroids rimming the solar system, first proposed as a theory in the 1940s, was ignored for more than forty years until renewed interest and technological breakthroughs confirmed the existence of the Kuiper Belt. Peebles also chronicles the discovery of ShoemakerLevy 9, a comet with twentytwo nuclei that crashed into Jupiter in 1994, releasing many times the energy of the world's nuclear arsenal. Showing how asteroid research is increasingly collaborative, the book provides insights into the evolution of scientific ideas and the ebb and flow of scientific debate.
