This still shows a stunning aurora captured from the International Space Station. Auroras are a space weather phenomenon that occur when electrically-charged electrons and protons collide with neutral atoms in the upper atmosphere. The dancing lights of the aurora provide a spectacular show for those on the ground, but also capture the imaginations of scientists who study the aurora and the complex processes that create them.
This frame is from a compilation of ultra-high definition time-lapses of the aurora shot from the space station. The full video is available here: https://youtu.be/PBJAR3-UvSQ
