最接近太阳的照片显示其被微小的耀斑覆盖

Closest ever images of sun reveal it is covered in miniature flares

The closest ever images of the sun reveal its surface is speckled with “campfires”, miniature versions of the dramatic solar flares visible from Earth.

科学家拍出了一张最接近太阳的照片。这张照片表明太阳的表面遍布“篝火”,也就是我们从地球上看到的大太阳耀斑的微型版本。

The observations, beamed back from the Solar Orbiter spacecraft, which is a joint Nasa and European Space Agency (ESA) mission, could help resolve why the sun’s atmosphere is so staggeringly hot compared to the surface – a central paradox in solar physics. Miniature flares have been proposed as a theoretical explanation for the so-called coronal heating problem, but until now no telescope has had a good enough resolution to observe the sun’s atmosphere in sufficient detail.

这些观测数据是由美国宇航局和欧洲航天局(ESA)的太阳轨道飞行器发回的,它有助于解释为何太阳大气层与表面相比如此热得惊人——这是太阳物理学中的一个主要悖论。微型耀斑被认为是对所谓的日冕加热问题的理论解释,但直到现在,还没有一台望远镜有足够的分辨率来观察太阳大气的足够细节。

The latest footage, taken at 77m kilometres (48m miles) above the solar surface between the orbits of Venus and Mercury, reveals flickering beacons, each spanning just a few hundred kilometres across and lasting minutes, before fizzling out again.

最新的照片拍摄于太阳表面上空770万公里(约合480万英里,位于金星与水星的轨道之间),它显示出太阳表面的有着闪烁的“光点”,每个光点的跨度只有几百公里,持续数分钟,然后再次消失。
