Aurora borealis. Panoramic view of the aurora borealis (northern lights) appearing in an arc over a river running from the Seljalandsfoss waterfall (right),Iceland. The aurora borealis is a coloured light display that is visible in the night sky at high latitudes. It occurs when charged and energetic particles from the Sun (the solar wind) are drawn by Earth's magnetic field to the polar regions. Hundreds of kilometres up,they collide with gas molecules and atoms,causing them to emit light | |
