Aurora borealis illuminating shoreline, time-lapse footage. This shoreline is in the Russian Arctic, with the auroral light (green) playing over trees and snow and ice on a tidal shoreline with rising and falling water levels. The aurora borealis is a coloured light display (the northern lights) 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.
