December night sky with winter constellations, Jupiter (right) with faint aurora borealis (northern lights, red hue). Aurora are caused by energetic charged particles from the Sun interacting with Earths atmosphere. The charged particles in solar wind are drawn by Earths magnetic field to the poles, where they collide with gas atoms and molecules, causing them to emit light. Photographed on 1 December 2023 in Shropshire, United Kingdom.
