银河系内出现神秘无线电信号

Mysterious Radio Signal is Coming from Inside our Galaxy

天文学家称，在我们自己的星系中已经探测到了神秘而强烈的射电能量爆炸。

Mysterious, intense blasts of radio energy have been detected from within our own galaxy, astronomers have said.

快速射电爆发（FRB）持续时间仅为几分之一秒，但其威力可能是太阳的1亿倍。尽管它们的强度很大，但它们的起源基本上仍是未知的。

Fast radio bursts, or FRBs, last only a fraction of a second but can be 100 million times more powerful than the Sun. Despite their intensity, their origin remains largely unknown.

现在，天文学家首次成功在我们的银河系中观测到快速的射电爆发。这次爆发比以往任何发现的爆发都要近之外，它们最终可以帮助解开它们来自何处的谜团。

Now astronomers have been able to observe a fast radio burst in our own Milky Way, for the first ever time. As well as being closer than any FRB ever detected before, they could finally help solve the mystery of where they come from.
