Show Me Science: Astronomy & Space - Comet - Visitors from Space

Comets have been causing fear in the minds of humans for millennia. Now new spacecraft are giving us insights into their composition and behavior. Comets allow us to study what the solar system was like in its formative period. They orbit the Sun in the Kuiper Belt and the Oort Cloud. This program teaches students about comets and helps students understand why comets cause both fear and fascination.
