Book Description
The spectacular collision of Comet Shoemaker-Levy 9 with Jupiter in July 1994 was a unique event in the history of astronomy. With a year's advance warning, astronomers and planetary scientists around the world were able to coordinate an observing campaign to track the event in unprecedented detail. A year after the event, a workshop at the Space Telescope Science Institute provided the first opportunity for them to bring together their observations and foster a new understanding of the impact. In this book, the editors present fifteen invited reviews from authors selected as international leaders in the study of the impact and its aftermath. They have edited and arranged the chapters to provide a thorough and comprehensive overview of our knowledge of the event. While our understanding of the impact will evolve with future work, this book provides a solid foundation for new insights.

Book Description
David Levy brings these "ghostly apparitions" to life. With fascinating scenarios both real and imagined, he shows how comets have wreaked their special havoc on Earth and other planets. Beginning with ground zero as comets take form, we track the paths their icy, rocky masses take around our universe and investigate the enormous potential that future comets have to directly affect the way we live on this planet and what we might find as we travel to other planets. In this extraordinary volume, David Levy shines his expert light on a subject that has long captivated our imaginations and fears, and demonstrates the need for our continued and rapt attention.

Book Description
As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects, and plans for high-tech hardware that could deflect an incoming object from a collision course – a procedure depicted, with little regard for scientific accuracy, in several Hollywood movies. Astrophysicist and science writer Andrew May disentangles fact from fiction in this fast-moving and entertaining account, covering the nature and history of comets and asteroids, the reason why some orbits are more hazardous than others, the devastating local and global effects that an impact event would produce, and – more optimistically – the way future space missions could avert a catastrophe.

Book Description
Molecules are found in a large variety of astronomical environments, ranging from comets in the solar system to galaxies at high redshift. This book brings together astronomers, physicists and chemists to discuss the use of molecules as probes of astrophysical parameters, explore their role in the evolution of astronomical objects, and study the basic chemical processes that occur in space.

Book Description
Portrays geologist Eugene Shoemaker and explains the scientific reasoning that led him to construct his "impact theory," in which collisions with comets created craters on the moon and several bodies in the solar system.

Book Description
The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.
