Aurora borealis and comet. View of the aurora borealis (northern lights) and the C/2013 R1 (Lovejoy) comet in the night sky. 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. Photographed in Hemnesberget, Nordland, Norway, in November.
