WHAT IS THE AURORA BOREALIS?
The Vikings believed that the lights were reflections of the Valkyries' armor as they marched towards Odin. Some Inuits thought that the lights in the sky were the spirits of their ancestors dancing and the Greeks associated these lights with bad omens.
Whatever the meaning the ancient people attributed to the lights, the Aurora Borealis is a sight to behold. With the advancement of the sciences, we know that the Aurora Borealis or the Northern Lights are caused by the Earth's atmosphere interacting with charged particles from the Sun during a solar flare.
As the particles from a solar flare reach Earth, they are channeled along Earth's magnetic fields towards the North and South poles. These particles then interact with the atoms and molecules in our atmosphere, exciting and causing them to release photons. These photons are the lights that we see in the sky during an aurora. Their southern counterparts are known as aurora australis.
