1·If aimed toward Earth, this outpouring of energy can interact with our magnetosphere, infusing molecules in the atmosphere with extra energy that then gets released as light, producing aurorae.
如果目标朝向地球，那么它爆发的能量会影响我们的磁层，向大气层中的分子注入额外的能量，能量释放时产生光，从而形成极光。
2·Astronomers studying the images found subtle differences between Saturn's northern and southern aurorae.
天文学家对这些图片研究发现，土星的南北极极光有细微的不同。
3·The photographer became fascinated with aurorae after working at a rocket launch site in the far north of Norway for 25 years.
摄影师米卡森在挪威最北部的火箭发射场工作了25年，从此便爱上了极光。
4·Aurorae are caused by the interaction between energetic charged particles from the sun and gas molecules in the upper atmosphere of the Earth.
极光是由地球大气上层的气体分子与来自太阳的高能带电粒子相互作用产生的。
