月亮飞船的系内星闻
胡德良 译
A neon green aurora is reflected in the waters off Yellowknife, Canada, in a newly released picture. | 在一张新发布的图片中,氖灯般的绿色极光倒影在加拿大耶洛奈夫附近的水面上。 |
Although best seen in clear, dark skies, auroras are products of the sun: When charged solar particles hit Earth's atmosphere, they infuse air molecules with extra energy, which then gets released as light. | 尽管极光在晴朗而黑暗的天空中显得最为清晰,但是它们是太阳的产物:当带电的太阳粒子冲击地球的大气层时,为空气分子注入了额外的能量,这种能量的释放表现为光。 |
