Magnetars can also be prone to a phenomenon known as starquakes which are just like earthquakes but on a star.

磁星也容易发生一种被称为星震的现象，这就像地震，但发生在一颗恒星上。

But this was back in the '90s, before scientists had the tools to observe starquakes in space.

霍尔：但那是在上世纪 90 年代，那时科学家们还没有工具来观察太空中的星震。

The most powerful of these starquakes ever observed was from a Magnetar called SGR 1806-20, about 50 000 light years away from us.

迄今为止观测到的最强力的星震来自于一颗名为 SGR 1806-20 的磁星，距离我们约五万光年。
