Northern lights. The Northern lights (aurora borealis) is a coloured light display that is visible in the night sky,usually only 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 in Iceland | |
