Have you ever witnessed nature's light show dancing across the night sky? This colourful display is often referred to, and known as ‘The Southern Lights’.
The sun is always active with a constant flow of ions ejecting solar flares. A solar flare is a cloud of ions, electrons and atoms. These charged particles from the solar flare travel through space towards Earth.
Earth has a magnetic field. The magnetic field acts as an invisible shield. When particles from the solar flare collide with the shield, they follow it and accelerate until they reach the poles. When they hit other chemicals they get excited and release light.
The spectacular Aurora Australis doesn't just occur in the South Pole it occurs in the North as well and is known as the Aurora Borealis or the Northern lights.
