Dragons may be make-believe, but a dragon-shaped aurora borealis that flickered in the sky over Iceland this month was breathtakingly real — just have a look at this dramatic photograph.
The photo, taken by Jingyi Zhang on Feb. 6, became NASA's astronomy photo of the day on Feb. 18 and has been widely viewed online since. It shows a swirling green aurora over a dark, snowy landscape where a solitary figure — the photographer's mother — stares up at the sky as if awestruck.
