原文:
Not fireworks, these intense shimmering lights still danced across Earth’s night skies late last month, seen here above the planet’s geographic south pole. The stunning auroral displays were triggered as a coronal mass ejection blasted from the Sun days earlier impacted the magnetosphere, beginning a widespread geomagnetic storm. The six fisheye panels were recorded with digital camera and battery in a heated box to guard against -90 degree F ambient temperatures of the long winter night. Around the horizon are south pole astronomical observatories, while beyond the Aurora Australis stretch the stars of the southern Milky Way.
中文翻譯:
在上個月底，地球的南極上空出現了璀璨的極光顯示，這些強烈閃爍的光芒並不是煙火。這令人驚嘆的極光展現是因為一個日冕物質拋射（coronal mass ejection）在幾天前從太陽爆發，影響了地球的磁層，從而引發了一場廣泛的地磁風暴。這六個魚眼鏡頭的畫面是使用數位相機和電池在保護箱中拍攝的，以抵禦-90華氏度的極寒長冬夜。環繞地平線的是南極天文觀測站，而在極光澳大利亞（Aurora Australis）之外，可以看到南方銀河的星空。
