Best astronomy photos of the year
Runner-up (Earth & Space), 'Divine Presence' by Ole C. Salomonsen (Norway).
Display of the Aurora Borealis, or Northern Lights, taken over ponds near Hillesøy in Norway, 11 March 2011. The aurorae are caused by the interaction between the Earth’s atmosphere and a stream of particles from the Sun known as the solar wind.
The Earth’s magnetic field funnels these particles down over the planet’s poles giving rise to the glowing curtains of coloured light.
