Natural Phenomenon

An aurora is a one of the most beautiful natural phenomena, which can be seen near the North and South Pole. We can't see that everyday. An aurora can be seen during the winter with very low temperature and you should be with good luck.

How nice is it!! The aurora is in the sky, where is 100 km far from the ground, and we can see it in the night. There are some types of aurora, it has different shape and colour. Usually, its colour is white or red-green.

How does the aurora come up? It's very complicating me but, basically, electrificated particles from the sun and magnetism systems of the earth cause an aurora. There is a "plasma seat" in the sky, and plasma photons geather into the seat. These photons start to light themselves when they fall down quickly to the earth.
