The Great Comet Crash is a record of the spectacular collision between Comet Shoemaker-Levy 9 and the giant planet Jupiter in July 1994. Researchers who were involved in all aspects of observing and interpreting the encounter give personal narratives of the events, from the discovery of the comet through to the dramatic effects on the appearance of Jupiter in the hours, days and months after the collision. The chapters are all by distinguished researchers who personally participated in the international teams who recorded the events. The book is illustrated in colour throughout by the very best images selected from professional observatories around the world. The Great Comet Crash is the definitive illustrated account by professional astronomers of the collision and its consequences.
