The Northern Lights, i.e. Aurora borealis is a phenomenon that occurs at the northern and the southern hemispheres.
In the north it is called Aurora borealis and in the south Aurora australis. The auroras have been proven to act alike and have similar shapes and colours at both poles at the same time.
Let’s check out a few of the most stunning northern lights videos:
In the winter time thousands of people travel to witness the amazing phenomenon every year. The Aurora borealis is one of the biggest factors to create tourism for example in the northern parts (i.e. the Lapland -areas) of the Nordic Countries.

These dancing lights usually have a pale green colour but can also be yellow, blue, turquoise, purple and even red, which is the most rare colour for these night sky lights.

How are they created?
The colours are born when gaseous particles in the Earth’s atmosphere collide with different types of charged particles from the sun. The colour of the aurora is defined by the type of the particles. For example the most common, green aurora is created by oxygen, the red ones by higher altitude oxygen and blue and purple by Nitrogen.

Where and when to spot them?
The best time to see them is in the winter because of the longer periods of darkness and clearer skies. You can see them for example in North America (Canada, Alaska etc), the northern parts of Greenland, Iceland, Norway, Sweden and Finland.
The auroras in the south aren’t spotted very often because they appear mainly above Antarctica and the southern parts of the Indian Ocean.
