In 2004, the radiation from the explosion caused by this starquake reached earth.

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

Move that magnetar and its starquake up to 10 thousand light-years away, and things would get much worse.

将磁星及其星震移动到1万光年之外，情况会变得更糟。

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。
