B. inggris Aurora

Aurora is a natural phenomenon that refers to northern light, southern light, and polar light. It is a colorful light display that appears in the sky at the evening and the night, seen in the sky of Artic and Antartica region.
Because the aurora is only found at those regions, people from different area have to spend much money and should prepare their physical condition to be able to witness it directly.
The aurora has complex mix color that will change every day. The beauty is surely a thousand times better than fireworks in the New Year's Eve. For this reason, some people really wish to see it once in a life time. Unfortunately, in order to see it in the artic and antartica, the travelers have to go through challenging and dangerous tracks. Therefore only few people can succeed to go there.
There is not yet detailed explanation about this wonderful phenomenon. However, based on some experts, the cause of aurora is basically involves the interaction between the solar wind with the Earth's magnetosphere. Initially, the solar storms send blast of charged solar particle. When the Earth is in the path of that particle stream, then the Earth's magneto sphere reacts.
At that time, the Earth electrons move to higher-energy orbits or further away from the nucleus. After that, the electrons move back to a lower-energy orbit. This process releases the particle light or photon which creates aurora.
