It's not common for the Northern Lights (Aurora Borealis, Nordlys) to glimmer in the skies as far south as Oslo, at least not as brightly as they did late Thursday Night.
Late Thursday, though, the Northern Lights suddenly sent their characteristic waves of green right over the capital.
The Northern Lights are generated when solar particles in space, guided to the magnetic fields of the Earth's north and south poles, are stopped by the Earth's atmosphere and collide with atmospheric gases. The collision energy between the solar particle and the gas molecule is emitted as a photon, or light particle, and many of them create an aurora, the waves of lights that appear to move across the night sky.
