那天是万圣节，天空看起来像个生物。究竟是哪一种生物，天体摄影师不确定（但也许你可以建议一个）。确切地说，导致2013年这一怪异现象的原因是确定的：那一年最好的极光之一。这壮观的极光有着不同寻常的高度细节。在这张图片中，鲜艳的绿色和紫色极光颜色是由大气中的氧气和氮气对入射电子爆发的反应引起的。挪威特罗姆瑟的桦树也形成了令人毛骨悚然的前景。通常，新的上镜的极光伴随着新的地磁风暴。几乎超空间：随机APOD生成器

It was Halloween and the sky looked like a creature. Exactly which creature, the astrophotographer was unsure (but possibly you can suggest one). Exactly what caused this eerie apparition in 2013 was sure: one of the best auroral displays that year. This spectacular aurora had an unusually high degree of detail. Pictured here, the vivid green and purple auroral colors are caused by high atmospheric oxygen and nitrogen reacting to a burst of incoming electrons. Birch trees in Tromsø, Norway formed an also eerie foreground. Frequently, new photogenic auroras accompany new geomagnetic storms. Almost Hyperspace: Random APOD Generator
