The lights of the Aurora generally extend from 80 kilometres (50 miles) to as high as 640 kilometres (400 miles) above the earth's surface.
Northern Lights can be seen in the northern or southern hemisphere, in an irregularly shaped oval centred over each magnetic pole. The lights are known as 'Aurora borealis' in the north and 'Aurora australis' in the south.
After a lot of research, scientists have discovered that in most instances northern and southern auroras are mirror-like images that occur at the same time, with similar shapes and colors. It is this uniqueness which attracts a lot of people to visit these place to look at such an unique feature.
