AURORA BOREALIS / AUSTRALIS

·         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

·         Aurorae are chiefly caused by sunspots, which are magnetic storms on the surface of the sun

·         Atoms discharge electrified particles into space

·         The earth’s magnetic poles attract these electrified particles coming from the sun

·         These electrified particles cause gases in the upper atmosphere or more appropriately the Magnetosphere to vibrate and glow in colours
