Auroras - Northern and Southern Lights

Even at 93 million miles away, the sun affects all life on Earth. (30 seconds, MPEG-1, 4 MB) In the video clip, a burst of material from the Sun heads towards Earth's magnetic field. This eventually sends high-speed electrons and protons into the Earth's upper atmosphere to form auroras.

A burst of energy from the sun can affect radio communication, UV exposure, and more. In fact, a massive ejection from the sun can affect satellites severely...And we need satellites for accurate weather reporting!
