NASA在南極發現完美矩形冰山

Usually when we think of icebergs, we don't imagine perfect geometric shapes.

想到冰山時，我們通常不會將其與完美的幾何形狀聯繫起來。

But that's exactly what NASA captured in an image posted on Twitter of an iceberg in what appears to be the shape of a perfect rectangle.

但美國宇航局近日在推特發佈的一張圖片上的冰山卻呈現出完美的矩形。

The image was captured during a flight for Operation IceBridge, the largest airborne survey of Earth's polar ice.

這張圖片是美國宇航局在執行“冰橋行動”時在飛行途中拍到的，“冰橋行動”是針對地球極地冰展開的最大規模的航空測量。

It even has a name: A tabular iceberg, a type of iceberg both broad and flat.

這種冰山甚至還有名字：平頂冰山，即又寬又平的冰山。

"The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf," according to a statement from NASA.

美國宇航局在一份聲明中稱：“這個冰山的直角和平坦表面顯示，它可能是最近才從冰架上崩解下來的。”

The iceberg is believed to have broken off from the Larsen C ice shelf.

據說，這座冰山是從拉森C冰架上掉下來的。
