In fact when this happens Cherenkov radiation can occur.

事实上，当这种情况发生时，就会发生切伦科夫辐射。

As high-energy particles shoot into them, traveling faster than light can travel in that medium, they create a cone of Cherenkov radiation, like a wake, that we can detect.

当高能粒子射入它们，以超过光在介质中传播速度的速度传播时，它们产生了我们可以探测到的切伦科夫辐射锥，就像尾流一样。

In other words, Cherenkov radiation, this strange phenomenon that happens when things move faster than the speed of light, is literally shedding light on the invisible realms of the universe.

换句话说，切伦科夫辐射，这种会在物体以比光速更快的速度移动时产生的奇怪现象，实际上就是在宇宙中看不见的领域发光。
