Scenes from Space #6

I've never personally seen the Northern Lights, but I'd love to someday. The Northern Lights - also called the Aurora Borealis - are caused by the interaction of solar flares from the the Sun with the Earth's magnetic field. They look like they are really close, but they actually occur 100 kilometers or more above the Earth's surface. September has been a great month for Northern Lights, because the Sun has been particularly active lately.
