AURORA

Hi EAP Class,

I am interested to share you with Aurora. Its  a natural interesting stuff. There are two Aurora which has seen in world. Scandinavian people watch the Aurora Borealis because of its closeness to the North Pole and we watch Aurora Australis from the sky of Australis as we are close to South Pole. I hope you will enjoy that.

Auroras are caused by charged particles, mainly electrons and protons, entering the atmosphere from above causing ionisation and excitation of atmospheric constituents, and consequent optical emissions. Incident protons can also produce emissions as hydrogen atoms after gaining an electron from the atmosphere.
