Video by @babaktafreshi | The Big Dipper stood high in the Iceland sky on this November night. The unusual northern light is known as a pulsating aurora. Although it’s faster in this time-lapse video, even in real time it shifts and brightens in patches every second, rather than the typical arcs and streaks. Auroras are caused by energetic electrons speeding down into Earth’s atmosphere and colliding with the thin air on the boundary of space and our atmosphere.⁣ Down on Earth is the iconic Skógafoss waterfall.
