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

磁层是个屏障，保护我们免受危险宇宙射线侵袭。

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

没有强大磁球层或稠密大气层，来自太空辐射将直射地面。

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——磁层向外延伸距离约为地球直径10倍。

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

木星磁气圈是太阳系里最大。要比太阳大多。

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

移动速度极快等离子体射流撞击磁极——也就是地球磁层边界。

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.

当它到候，它会产生足以猛烈压缩地球磁场冲击波，还会向磁层里传能量。

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

阿切尔团队提出，未来研究将着眼于能揭示更多磁层行为地基传感方法。

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，它是种由地球磁场所产生气体层。

" And that was really ideal for trying to tease apart exactly what happens when something impulsive hits our magnetosphere."

“对于尝试梳理冲击性物体撞击地球磁层后情况来说，这真是非常理想状态。”

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

这些来自太阳粒子大部分被地球磁场偏转，但是些粒子成功到并轰击着大气层。

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

围绕着地球磁场被称为磁层，就像个磁体拥有个南极和个北极。

And even though they're happening over 90 million miles away, they're so powerful that their effects can linger in our magnetosphere and atmosphere for days or weeks.

尽管发生在9000万英里以外, 但却如此强大, 以致于这样效果会停留在我们大气层和 磁层数天或数周之久。

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沙漠高速公路上行驶，车上无线电刚好调到木星磁气圈发出声音。

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