A radical change from our peaceful night sky, Cosmic Collisions presents the spectacular result of gravity pulling together planets, stars, and galaxies. Here are explosive encounters that ended the age of the dinosaurs and gave birth to new stars, but also created conditions essential for life on earth—the Sun's warmth, ocean waves. Cosmic Collisions provides an extraordinary view of these forces—constructive or catastrophic—that continue to affect our universe.

Cosmic Collisions was developed by the American Museum of Natural History, New York (www.amnh.org) in collaboration with the Denver Museum of Nature & Science; GOTO, Inc., Tokyo, Japan; and the Shanghai Science & Technology Museum. Cosmic Collisions was created by the American Museum of Natural History with the major support and partnership of NASA, Science Mission Directorate, Heliophysics Division.
