New video from the Cassini spacecraft orbiting Saturn captures spectral forms of the planet’s northern lights for the first time. These curtains of color result when charged particles from the planet’s magnetosphere pierce the planet’s upper atmosphere. The aurora tower 1,200 kilometers above Saturn’s northern hemisphere, making them the tallest in the solar system. — Lisa Grossman, November 25, 2009
