What are the Northern Lights, and what causes them?
The Northern Lights are a unique natural phenomenon created when electrically charged particles from the sun collide in the Earth’s atmosphere. The colour variation depends on the kind of gas particles involved – low-lying oxygen causes the most common green colour, red is produced by oxygen higher in the atmosphere and the blueish-purple hue comes from nitrogen.
The result is a truly magical sight to behold as the vibrant colours snake across the night sky, dancing around as if moving to some unheard music.
Mystical explanations
The Latin name translates to ‘dawn of the north’, Aurora being the Roman goddess of the dawn. Steeped in myth and viewed in awe, these lights have captivated humanity for millennia.
The Sámi – the indigenous people of Sweden – believed the lights were the souls of the dead. You weren’t to dance, sing or whistle at them for fear they would feel disrespected and the lights would dip down and carry you off to the afterlife. The Vikings, on the other hand, thought that the Northern Lights were the Valkyries taking fallen soldiers to meet Odin, their chief god.
