欣赏美丽，惧怕野兽。美丽的是头顶上的极光，它以一个巨大的绿色螺旋的形式出现，在风景如画的云层之间，明亮的月亮在旁边，星星在背景中。野兽是产生极光的带电粒子波，但有一天可能会破坏文明。1859年，随着全球各地都能看到引人注目的极光，与太阳耀斑有关的日冕物质抛射（CME）产生的带电粒子脉冲强烈地影响了地球的磁层，从而产生了卡林顿事件。来自太阳的猛烈冲击将地球磁场压缩得如此之大，以至于在电报线路上产生了高电流和火花，震惊了许多电报操作员。如果卡灵顿级的事件今天撞击地球，人们推测，全球电网和电子设备可能会受到前所未有的破坏。这张特色极光是2016年在冰岛的Thingvallavatn湖上拍摄的，这个湖部分填补了分隔欧亚大陆和北美构造板块的断层。几乎超空间：随机APOD生成器

Admire the beauty but fear the beast. The beauty is the aurora overhead, here taking the form of a great green spiral, seen between picturesque clouds with the bright Moon to the side and stars in the background. The beast is the wave of charged particles that creates the aurora but might, one day, impair civilization. In 1859, following notable auroras seen all across the globe, a pulse of charged particles from a coronal mass ejection (CME) associated with a solar flare impacted Earth's magnetosphere so forcefully that it created the Carrington Event. This assault from the Sun compressed the Earth's magnetic field so violently that it created high currents and sparks along telegraph wires, shocking many telegraph operators. Were a Carrington-class event to impact the Earth today, speculation holds that damage might occur to global power grids and electronics on a scale never yet experienced. The featured aurora was imaged in 2016 over Thingvallavatn Lake in Iceland, a lake that partly fills a fault that divides Earth's large Eurasian and North American tectonic plates.
