Northern lights also known as aurora or polar lights, are bright lights which are normally caused by the collision of the particles which are electrically charged by the sun from the earth’s atmosphere. The lights are usually visible on the magnetic poles of both the southern and northern hemisphere. In the South, the northern lights are known as Aurora australis’ and in the North; they are called ‘Aurora borealis. The northern lights are normally displayed in very many colors but the most common are pink and pale green.
There are other shades like blue, violet, green, red and yellow that have also been reported. The lights will in most cases appear in the form of scattered clouds and patches of light that is similar to arcs, streamers, shooting rays or rippling curtains and usually light up in the sky with a bright and eerie glow. The collision among the gaseous particles of the earth’s atmosphere and the charged particles form the atmosphere of the sun resulting in the auroras. The different colors of the aurora usually come about as a result of the collision of certain type of gas particles. The most common, the yellowish-green which is pale is a production of oxygen molecules that are about sixty miles away from the earth while the red northern lights are caused by oxygen in high altitude and is like two hundred miles above the earth.
The Northern lights present a natural phenomenon that is normally found in southern and northern hemispheres which is beyond doubt awe inspiring.
