Supernovas (2x9)

Air date: Feb 12, 2008

A stellar explosion, the supernova is the sensational death of a star. It can shine as bright as 100 billion suns and radiate as much energy as the Sun would emit over 10 billion years. Jets of high-energy light and matter are propelled into space and can cause massive gamma ray bursts and emit intense X-ray radiation for thousands of years. Astronomers believe that this process creates the very building blocks of planets, people and plants.
