Description
A composite image with the milky way and the Aurora Borealis over spruce trees in Alaska. The Aurora Borealis (northern lights) is an atmospheric phenomenon that occurs at high latitudes, appearing as shimmering bands of coloured light in the sky. It occurs when charged particles in the solar wind are directed towards the poles by Earth's magnetic field. There they collide with atoms in the upper atmosphere, causing them to emit light. The colour of the light depends on the atmospheric gas involved. Green is produced by excited atomic oxygen. Photographed near Wiseman, Northern Alaska.
