Aurorae (Northern Lights)

Beautiful ribbons of light caused by the interaction of high-energy particles in the solar wind and Earth's magnetic field. These are common in both extreme northern (aurora borealis or northern lights) and southern latitudes (aurora australis/southern lights), near Earth's magnetic poles.
