Secrets of the Sun


Nova reviews what scientists have learned in recent years about the sun's behavior and how it works. Most significantly, astronomers are at last beginning to understand the the solar phenomenon that impact our civilization; solar flares and coronal mass ejections.

Nova examines current research on the Sun. It looks at the dangers posed by solar flares and follows scientists as they monitor a large solar flare heading toward earth in 2011. It also discusses the causes of solar flares and looks at the launch the Solar Dynamics Observatory (SDO) which offers uninterrupted coverage and high-resolution observation of the sun.
