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-物质抛射的不存在。

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

来自太阳的物质喷射也许是你从未听说过的最危险的东西。

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，进可以产生太阳黑子、太阳耀斑和物质抛射。

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

Though some flares do not result in coronal ejections, when they do, the star spews out hot, radiated clouds of plasm.

尽管有一些耀斑不会导抛射，当它们发生时，它们会抛射出炽热的带有辐射的等离子云。

When the DSCOVR satellite records an ejection, it will release a warning.

当DSCOVR卫星记录到抛射时，就会发送警报。

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

也许当时发生了物质抛射。”

Coronal ejections usually occur during a sun flare, which is a sudden increase in energy output on the surface of a star.

抛射通常发生在太阳耀斑期间，是恒星表面能量突然的爆发。

Mr. Berger says we cannot stop the ejections from affecting us, but we can prepare for them if we know when they will happen.

伯格说我们不能阻止这些抛射影响我们，但如果抛射发生，我们可以做好应对的准备。

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物质抛射，或 CME。

While they're actually very common, these ejections just need to be the correct strength and trajectory to cause mayhem for anything caught in their path.

虽然它们非常的常见，但这些喷出物只需要有足够的动力和在正确的轨道下就会对行进道路上的任何物体造成灾难。

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。

Young says studying the sun helps scientists understand solar phenomena that affect our lives like solar winds and coronal mass ejections which he calls huge burps of solar material.

杨说，研究太阳有助于科学家理解影响我们生活的太阳现象，比如太阳风和物质抛射，他称之为太阳物质的巨大撞击。

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，这叫物质抛射。

In the wake of Mr Zeidan's ejection the city's military council, which co-ordinates Tripoli's various local militias, issued an order for the withdrawal of forces occupying strategic positions.

随着扎伊丹被负责协调黎波里大量当地的民兵的军事委员会，他们提出撤回武装占领战略位置的要求。

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、太阳耀斑及物质抛射组成, 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射入太空。

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.

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。
