What are meteorites? Where do they come from? Are they a threat? What are they made of? How common are they? As centuries have passed, our knowledge of these extraterrestrial objects has advanced immensely, and today, the scientific study of meteorites provides a wealth of information about the solar system. Meteorites reveal clues to some of the greatest scientific enigmas: <P><UL> <li> the origin of life on Earth <li> the mass extinction of species <li> the nature and composition of asteroids <li> the conditions during the formation of the solar system <li> the dust from stars that died long before our Sun formed. </ul><p> Written by a team of experts, Meteorites is an accessible, comprehensive guide that features over two hundred full-color photographs, diagrams and graphs. Look no further for a wonderful introduction to these powerful, yet mystifying, objects.
