Northern lights. The Northern Lights are created as electrically charged particles from the Solar wind are pulled in toward the magnetic poles by the Earth's magnetic field. As these particles collide with the atoms of gas in the ionosphere about 80km above the ground,they give the atoms energy and they become 'excited'. The atoms spontaneously release this energy in discrete amounts,resulting in particular colours of light being emitted. Photographed in the Swedish Arctic | |
