History and Composition of Comets

The video discusses the nature of comets, focusing on their composition and behavior as they approach the sun. It highlights the historical prediction of Haley's Comet using Newton's Laws and details the Deep Impact mission to Comet Temple One. The mission involved a probe designed to collide with the comet, allowing scientists to analyze the resulting debris. The findings revealed less water than expected and the presence of fine particles, providing insights into the comet's composition.
