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.

移动速度极快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。
