Northern Lights By Mr Frosty

So what exactly is the
An aurora is a natural display of light in the sky and it can be found at both poles. Near the South Pole they are the Southern Lights (Aurora Australis), and near the North Pole they are the Northern Lights.
The aurora is caused by the collision of energetic charged particles with atoms in the high atmosphere. The charged particles originate in the solar wind and are directed by the Earth’s magnetic field into the atmosphere. The solar wind is the result of processes on the sun’s surface which throw particles far out into space.
Collisions with oxygen produces yellows and greens and reds. Collisions with atoms of nitrogen give off a blue colour. The light displays can be seen for just a matter of minutes or up to an entire evening.
