Aurora borealis seen over trees through a fish-eye lens, with an observer at far right. This light display (the northern lights) is seen 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. Photographed over Alaska, USA, in 2000.
