Horizon. Comet of the century. Season 50, Episode 5

Description

Comet ISON has been travelling towards the sun for ten thousand years, and across the globe scientists are following its process. As well as providing a stunning spectacle, ISON's tail of vapourised gas and water, hundreds of millions of kilometres long, gives insights into some of the greatest mysteries of science; it will help explain the origins of the solar system, whether earth's water was delivered on comets and even whether we are alone in the universe.
