Low earth orbit is probably a lot closer than wherever those radio bursts came from.

近地轨道可能比那些无线电脉冲来自的地方要近得多。

And scientists say they have detected some sort of signal from outside it, fast radio bursts that repeat.

科学家们说，他们已经探测到某种来自外部的信号，快速无线电重复爆发。

Radio bursts, which are signals that only last for a millisecond or so, aren't that rare in space.

无线电脉冲，这种信号只能持续一毫秒左右，在太空中并不罕见。

Stay tuned for a sequel, as researchers try to understand exactly how the magnetars produce these radio bursts.

请继续关注后续报道，因为研究人员试图确切了解磁星是如何产生这些射电暴的。

Fast radio bursts — short, powerful flashes of radio waves from distant galaxies— have tantalized astronomers for 13 years.

快速电波爆发——来自遥远星系的短而强大的射电波闪光——13 年来一直在诱惑着天文学家。

Fast radio bursts are a real mystery.

快速射电暴是一个真正的谜。

Number three are fast radio bursts.

第三个是快速射电暴。

There are probably more theories about what makes fast radio bursts, than there are actual detections of these things.

可能有更多关于是什么产生快速射电暴的理论，而不是对这些东西的实际检测。

Considered one of the biggest mysteries in astronomy, fast radio bursts or FRBs were first discovered in the year 2007 and since then, over two dozen of them have been observed.

被认为是天文学中最大的谜团之一，快速射电暴或 FRB 于 2007 年首次被发现， 从那时起，已经观察到超过两打。
