Physics in Action: Space Weather
Description:
This photo (hi-res version) shows the Aurora--the Northern Lights--over Alaska. The green color comes from the spectral lines of oxygen. For an image of the Southern Lights, taken from space, see NASA's Earth Observatory.

Auroras are produced by magnetic storms in space. To learn about space weather, you can visit Physics in Action: Space Weather, from the American Physical Society's Physics Central, and NASA's Space Weather Center.
