NOTES
Aurora Borealis or northern lights and Aurora Australis or
southern lights are multi coloured lights that sweep across the sky in waves
and are visible in the Arctic region and Antarctic region respectively. They
Aurorae are chiefly caused by sunspots, which are magnetic storms on the
surface of the sun. These atoms discharge electrified particles into space. The
earth’s magnetic poles attract these electrified particles coming from the sun.
These electrified particles causes gases in the upper atmosphere or more
appropriately the Magnetosphere to vibrate and glow in colours.
