History of the Northern Lights

The Northern Lights were once known to the Vikings as the battle charge of the Valkyries; Norse mythical figures who oversee battle, deciding who lives and who dies. 

Their armour was said to shimmer in the darkness and create the colours of the Aurora Borealis.

Why are the Northern Lights called Aurora Borealis?

Pierre Gassendi was a 17th century French scientist who coined the name Aurora Borealis. With Aurora stemming from the Roman Goddess of dawn, and Borealis comes from the Greek word boreas for the north wind.

The Science of Aurora Borealis

The science behind the phenomenon is less romantic than the Norse mythological version, but no less fascinating. 

The Northern Lights are produced when solar wind, which is made up of charged particles from our sun, interacts with our atmosphere. The charged particles make the gases in our atmosphere glow, like a florescent tube light. 

The colour depends on which gas in our atmosphere the particles collide with, with oxygen creating the yellow-green colour and nitrogen creating the crimson.

Where can I see the Northern Lights?

The earth’s magnetic field diverts the solar wind to our poles which is why the phenomenon only happens in the high north, or far south (called Aurora Australis). 

Up in the northern hemisphere though, Alaska and Canada are good viewing spots, but in Europe, you must to head to Iceland or Scandinavia, with Norway being the best and most popular place to see them.
