This timelapse video was taken by ESA astronaut Alexander Gerst as he flew over New Zealand on the International Space Station at around 400 km altitude. The nighttime video shows an aurora that occurs when Earth’s atmosphere interacts with solar radiation. The International Space Station travels at 28 800 km/h meaning that it only takes 90 minutes to circle Earth completely. Footage: European Space Agency
