The magnetosphere is a shield, protecting us from dangerous cosmic rays.

磁层是一个屏障，保护我们免受危险宇宙射线的侵袭。

You don't see similar flashes here on Earth, because the magnetosphere doesn't let cosmic rays reach you.

你们在地球上没有看到过类似的闪光，因为地球磁层不会让宇宙射线接触到你们。

Without an extensive magnetosphere, or a dense atmosphere, half of all radiation coming from space reaches the ground.

没有强大的磁球层或稠密的大气层，来自太空的一半辐射将直射地面。

The magnetosphere of Jupiter is the biggest object is the solar system, is a lot bigger than the Sun.

木星的磁气圈是太阳系里最大的。要比太阳大得多。

You had a jet of plasma traveling very fast that impacted on the magnetopoles-that's the boundary of our magnetosphere.

移动速度极的等离子体射流撞击磁极——也就是地球磁层的边界。

On top of that, Mars also has no magnetosphere so no protection against radiation.

最重要的是，火星也没有磁层，因此没有防辐射措施。

Most of the particles from the sun are deflected by the Earth's magnetosphere, but some make it through to bombard the atmosphere.

这些来自太阳的粒子大部分被地球磁场偏转，但是一些粒子成功到达并轰击着大气层。

These events occur on a colossal scale-the magnetosphere extends outward about 10 times the diameter of the earth.

这些是庞大规模事件——磁层向外延伸的距离约为地球直径的10倍。

Calm down, Magneto. Now the magnetosphere is the area around the Earth in which the Earth's magnetic field is felt.

冷静，万磁王。磁圈就是地球周围能够感受到磁场的范围。

When it arrives, it causes a shockwave that violently compresses the Earth's magnetic field and transfers energy into the magnetosphere.

当它到达的时候，它会产生足以猛烈压缩地球磁场的冲击波，还会向磁层里传达能量。

Archer's team has proposed that future studies look into ground-based sensing methods that can reveal more about the magnetosphere's behavior.

阿切尔的团队提出，未来研究将着眼于能揭示更多磁层行为的地基传感方法。

Remember the whole " Mars has no magnetosphere" thing?

还记得“火星没有磁层”这件事吗？

The invisible magnetosphere shields us from the dangerous ionising radiation of space.

看不见的磁层保护我们免受危险的太空电离辐射。

The magnetic field around the Earth is called the magnetosphere, and like a magnet, it has a north pole and a south pole.

围绕着地球的磁场被称为磁层，就像一个磁体拥有一个南极和一个北极。

Earth's magnetosphere wouldn't be able to protect you from space radiation blasting from all directions.

地球的磁层无法保护您免受来自各个方向的太空辐射冲击。

If you find yourself driving on a dark desert highway, your AM radio might just tune in to the strange sounds of Jupiter's magnetosphere.

如果你发现自己在昏暗的沙漠高速公路上行驶，车上的无线电刚好调到木星磁气圈发出的声音。

To understand the cause of auroras, first picture the Earth enclosed by its magnetosphere, a huge region created by the Earth's magnetic field.

为了解北极光成因，我们需要了解被磁层包围地球，它是一种由地球磁场所产生的气体层。

In 2007 NASA launched five satellites to study the magnetosphere, in a mission called Time History of Events and Macroscale Interactions during Substorms, or THEMIS.

2007年，在亚暴期间事件的时间历史和宏观相互作用的任务中，美国国家航空航天局发射了5颗卫星来研究磁层。

Another explanation is that a freak disturbance of the Earth's magnetosphere due to solar wind can cause a ship's instruments to go haywire, effecting navigation.

另一种解释是，由于太阳风引起的地球磁层异常扰动会导致船舶仪器失灵，影响航行。

They have the potential to overload power grids, disrupt communication channels, and interact with Earth's own magnetosphere so astronomers pay close attention to the rare CME pointed toward Earth.

它们有可能使电网过载，破坏通信信，并与地球自身的磁层相互作用，因此天文学家密切关注指向地球的罕见日冕物质抛射。
