Gaseous particles colliding in the sky create the most amazing lightshow you’ll ever see. The colours change – green, yellow and blue are among the most common Aurora shades – and the movement varies, too. Sometimes you’ll see a quick flash, other times there’s a soft, long glow along the horizon and often they dance before your eyes. You’re never guaranteed to see the northern lights, but your best chance is to go as far north as possible.
