Coronal mass ejections from the Sun are perhaps the most dangerous threat you've never heard of.

来自太阳的日冕物质喷射也许是你从未听说过的最危险的东西。

These events are known as coronal mass ejections or CMEs.

这些事件被称为日冕物质抛射（CMEs）。

Solar flares and coronal mass ejections often occur near sunspots.

太阳耀斑和日冕物质抛射经常发生在太阳黑子附近。

Another type of solar eruption is called a coronal mass ejection, or CME.

另一种类型的太阳喷发被称为日冕物质抛射，或 CME。

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

当被称为“日冕物质抛射”的强烈太阳风涌向地球时，就会发生这种风暴。

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

也许当时发生了日冕物质抛射。”

These solar flares and Coronal Mass Ejections, or CMEs, can hit Earth and have serious consequences for humanity.

这些太阳耀斑与日冕物质的喷发（简称CME），会击中地球并对人类造成严重的后果。

An absence of sunspots also means an absence of solar flares and their more violent siblings, coronal mass ejections.

缺少太阳黑子也意味着太阳耀斑以及它们更强烈的同胞-日冕物质抛射的不存在。

A coronal mass ejection from a filament lifted off the sun on March 3rd, according to the U.S. government.

据美国政府称，3月3日，从暗条变成的日冕物质抛射飞出了太阳。

Coronal mass ejections range in speeds, but they can occur as quick as 800-900 miles per second, which is extremely fast and they expell a massive amount of material.

日冕物质喷射，其抛射速度会有变化，但是有时候它们能以每秒800至900英里速度抛射，这是非常快的速度。

About a day or two later, the biggest part of the storm arrives. It is called a coronal mass ejection.

大约一两天后，太阳风暴中最大的一部分会抵达地球，这叫日冕物质抛射。

The sun's strong magnetic energy is the source of solar flares and bursts of plasma known as coronal mass ejections.

太阳的强磁能是太阳耀斑和被称为日冕物质抛射的等离子体爆发的来源。

Extreme solar storms called " coronal mass ejections" can erupt into space almost without warning, unleashing huge waves of charged particles.

名为日冕物质抛射能的极端太阳风暴毫无预警地向宇宙爆发，释放巨大的带电粒子波。

Hot plasma moves inside the Sun, creating magnetic fields, which in turn can create sunspots, solar flares, and coronal mass ejections.

炽热的等离子体在太阳内部移动，产生磁场，进而可以产生太阳黑子、太阳耀斑和日冕物质抛射。

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学家所说的“日冕物质抛射”的伤害，这种强风暴发生在太阳的表面。

While sunquakes and solar tsunamis pose no danger to Earth, the violent action of a flare frequently triggers dangerous eruptions called coronal mass ejections, or CMEs.

而日震和太阳海啸，不会给地球造成危害，耀斑剧烈的活动，经常会引发危险的喷发，这被称为“日冕物质喷射”，简称CME。

Although this is slower than the speed of the light and materials emitted by solar flares, coronal mass ejections can have much more dramatic effects on Earth.

虽然这比太阳耀斑发射的光和物质的速度要慢，但日冕物质抛射对地球的影响要大得多。

These explosions are known as coronal mass ejections.

这些爆炸被称为日冕物质抛射。

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质抛射的东西，这就是为什么我们喜欢用不同的波长来观察它的原因。

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.

日冕物质抛射的美妙之处在于，这是一个我们可以用肉眼看到太空的天文事件。
