New images of the Sun show areas never seen before
新影像展示了太阳上前所未见的区域
文字稿
A view of the Sun that's never been seen before – its south pole.
这是一个前所未见的太阳上的景象——它的南极。
The shimmering bright atmosphere is its hottest part, at a million degrees Celsius.
微微闪烁的明亮大气层是它最热的部分，温度达到了一百万摄氏度。
The darker lofted clouds are cooler wisps of gas, but still at a searing several thousand degrees.
颜色较暗的漂浮着的云团是温度较低的一缕缕气体，但它们仍有数千度的灼热高温。
The pictures have been taken by the European Space Agency's Solar Orbiter spacecraft.
这些画面是由欧洲航天局的航天器 “太阳轨道飞行器” 拍摄的。
They're the closest and most detailed ever taken, and they'll help scientists learn how the star that gives us life on Earth actually works.
这些画面是迄今为止距离最近、细节最丰富的太阳影像，它们能帮助科学家研究这颗赋予了地球生命的恒星究竟是如何运转的。

"From Earth, the Sun seems like a bright, featureless disc. But at certain frequencies, space telescopes can reveal its detailed structure, how magnetic fields twist and turn on its surface to create solar flares and loops of gas. No one really knows how these magnetic fields work, because scientists are unable to see how they move and shift on the north and south poles. But now, they can."

“从地球上看去，太阳就像一个明亮的、毫无特征的圆盘。不过在特定的频率下，太空望远镜能展示出太阳的详细结构，比如磁场如何在它的表面扭曲变形从而创造出太阳耀斑和气体环。没人知道这些磁场是如何运作的，因为科学家无法看到这些磁场在南北两极是如何运动和变化的。不过现在，他们能看到了。”
Professor Lucie Green, Astrophysicist, University College London
"The reversal of the polar magnetic fields on the Sun is, for me I think, one of the big open questions in science. And what we'll be able to do with Solar Orbiter is measure, for the first time, really important fluid flows that grab pieces of the magnetic field of the Sun and transport them to the polar regions."
露西·格林教授 伦敦大学学院天体物理学家
“太阳上的磁极反转对我来说是悬而未决的重大科学问题之一。而借助太阳轨道飞行器，我们将能够做到的就是首次测量至关重要的流体流动，这种流动会抓取太阳磁场的碎片，然后把它们输送到两极区域。”
The new research will help scientists learn more about our closest star and predict its raging moods.
这项新研究能帮助科学家更多地了解这颗距离我们最近的恒星，并预测它的 “暴脾气”。
