One Strange Rock - Season 1 - Eps 3: Shield
Earth protects itself from the sun. The David and Goliath story of Earth's relationship with its greatest threat, our seemingly benign Sun. The Sun is the big violent boss of the Solar System, throwing out devastating particles and energy. Without several shields, one generated by our unique planetary core, another by our atmosphere, and a third by our interconnected weather systems… life on Earth would never have survived.
