The corona extends for millions of kilometers.

日冕可以延伸数百万公里。

And there's one final layer above that: the ethereally thin corona, sort of like the Sun's atmosphere.

更加稀薄的日冕层，有点像太阳的大气层。

Only during an eclipse can we study the corona and other dim things.

只有在日食期间，我们才能研究日冕和其他昏暗的物体。

This is what people are talking about when they refer to the dangers of solar storms and coronal mass ejections, which are essentially when the Sun spews out plasma that, along with its embedded magnetic field, can reach Earth.

这就是人们口中的太阳风暴和日冕物的危险问题，本上是太阳喷出等离子体，连同它的嵌入磁场，到达地球。

The hellish solar corona rages at millions of degrees.

凶狠的日冕以数百万度的温度呼。

Such storms happen when strong surges of solar winds called coronal mass ejections reach Earth.

被称为“日冕物”的强烈太阳风涌向地球时，就会发这种风暴。

At seven million to ten million kilometers above the sun's surface, we reach the corona, the outermost layer of the sun.

在太阳表面 700 万至 1000 万公里的上方，我们会到达日冕，也就是太阳的最外层。

And maybe at that time, there is what is known as a coronal mass ejection.

也许时发了日冕物。”

Yeah, so another big, long-standing question about the sun is the corona.

是的，另一个长期存在的关于太阳的重要问题是日冕。

Aristotle also thought that the earth was smaller than the other planets; a claim that was challenged by Eratosthenes, who used the shadows of sundials in Alexandria and Syene to calculate the circumference of the earth.

亚里士多德还认为地球比其他行星小；埃拉托色尼对这一说法提出了疑，他使用亚历山大和赛伊尼的日冕阴影来计算地球的周长。

The Advanced Space-Based Solar Observatory, or the ASO-S, will provide critical insights on the two most violent activities of Earth's closest star: solar flares and coronal mass ejections, along with the powerful radiation and complex magnetic fields they generate.

先进天基太阳天文台将对地球上最近的恒星——太阳上两类最剧烈的爆发现象提供关键的见解：太阳耀斑和日冕物，以及它们产的强大辐和复杂磁场。

The beauty of nice coronal mass ejections is that we get to have an astronomical event basically come to us from space that's visible to the naked eye.

日冕物的美妙之处在于，这是一个我们可以用肉眼看到太空的天文事件。

It consists of solar wind, solar flares and coronal mass ejections, which are these giant bubbles of plasma and magnetic fields from the sun that send high speed particles into space.

它由太阳能风能、太阳耀斑及日冕物组成, 就是这些来自太阳的巨大泡沫等离子体及磁场将高速粒子入太空。

We can see big explosions things called solar flares or coronal mass ejections and that's why we like to look at it in all these different wavelengths

我们可以看到大爆炸，被称为太阳耀斑或日冕物的东西，这就是为什么我们喜欢用不同的波长来观察它的原因。

All that magnetic activity also leads to solar flares, which are bright bursts of radiation, and coronal mass ejections, or CMEs, which spit magnetized plasma out into space.

所有这些磁活动还会导致太阳耀斑，而这是明亮的辐爆发以及日冕物（CME）——将带有磁性的等离子体喷到太空中。

But we are not fully protected from what scientists call Coronal Mass Ejections. These are strong storms that can happen on the sun's surface.

但我们不能完全避免科家所说的“日冕物”的伤害，这种强风暴发在太阳的表面。

" We can actually see the spacecraft flying through coronal structures that can be observed during a total solar eclipse, " Raouafi said.

" 我们能够真切地看到该航天器穿过日冕结构，这种结构在日全食时期间可以被观测到。"

The " CO" from " corona" , the " VI" from " virus" , the " D" from " disease" and the number 19 from the year 2019 when the virus first appeared gave us a word that we just couldn't stop using in 2020.

" CO" 出自" 日冕" 一词，" VI" 出自" 病毒" 一词，" D" 来自" 疾病" 一词，以及数字" 19" 是因为病毒首次出现在2019年，给了我们一个在2020年根本无法停止使用的词。

But before that it has to weave through the granulosa cells that form the oocyte's outermost layer, known as the corona radiata.

但在此之前，它必须穿过形成卵母细胞最外层的颗粒细胞，称为辐日冕。

When a balloon-shaped CME reaches Earth, our planet is enveloped in supercharged particles that interact with our own magnetic field.

气球形状的日冕物到达地球时，我们的星球被笼罩在与地球磁场相互作用的增压粒子中。
