The Green Light

Another picture of the northern lights, taken in my back garden. It looked amazing, like a huge stream of green dust falling from the sky all around you.

 

This glow is caused by high-energy electrons colliding with oxygen atoms and nitrogen molecules. The basic process is the same as that of a neon sign, which involves a vacuum and a high voltage electrical discharge.

 

The electric power is generated by a combination of the solar wind, a hot ionized gas blowing out from the sun, and the Earth's magnetic field. This produces more than 1,000 times the electrical power of the world's largest power plant. (source)

 

For a good source of info, I recomend the wikipedia article.

 

I am glad you stopped by, I hope you like my photos. Any comments or criticisms are much appreciated.
