Aurora Borealis, nature's own psychedelic lights


Image result for why aurora borealis happens

When charged particles carried by solar wind from the sun
Hit the Earth most are deflected by Earth’s magnetic field
At the poles magnetic field being weak they enter the atmosphere
Colliding with the atoms exciting the electrons to a higher state
Dropping back to lower state they emit colourful lights Aurora Borealis

Aurora Borealis or the northern lights at the north pole
Aurora Australis the lights by similar phenomenon at the south pole
dance away like the psychedelic lights at a disco
Aptly to be named nature’s psychedelic lights zingo!
Dancing in pale green,pink  red, yellow, green, blue, and violet colours

The colours depend on the gas molecules they strike
Common green colour is due to oxygen molecules spike
Pure red due to high altitude oxygen around 200 likes hike
Breathtaking coloured lights dance by fluctuations of solar wind
A sight to behold  by the blessed watchers thrilling them no end

They dance from 50 miles to as high as 400 miles in a visual treat
Best seen in winter months over north pole in long darkness on the trot
Best parts to see north-western parts of Canada, southern tip of Greenland,
Iceland, Norway, Siberia. Southern aurora few and not seen year around
They keep the on looking watchers spell bound

Aurora Borealis means dawn of the north
Aurora Australis means dawn of the south
With ancient medieval beliefs and myth
Myth or not no myth when they dance and allure
Stealing the hearts world over in enthralling trance, sure!
