An impressive display of the northern lights and the milky way in the Brooks Range, Alaska, USA. The Aurora Borealis is a natural light phenomena that is visible in the night sky, usually only at polar 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.
