Officially known in the Northern hemisphere as the aurora borealis, the Northern Lights are natural phenomena featuring beautifully coloured light displays over the Earth. The lights are seen above the magnetic poles of the northern hemispheres.The Northern Lights are actually the result of collisions between gaseous particles in the Earth’s atmosphere and charged particles released from the sun’s atmosphere. Their displays appear in many colours. The most common are pale-yellowish green and pink. Shades of red, yellow, green, blue, and violet have also been reported.Variations in colours are due to the type of gas particles that are colliding. For example, the pale yellowish-green is produced by oxygen molecules located about 60 miles above the Earth. The red colour is produced by high-altitude oxygen, at height of up to 200 miles. Nitrogen produces blue or purplish-red aurora Each appearance of the Northern Lights is unique. Often you see three green bands across the night sky or the lights come as flickering curtains or rolling smoke. The colour is luminous green, often with a hint of pink along the edge, and occasionally with a deep violet centre.What is the purpose of the text?
