Astronomers have discovered the biggest explosion we have ever seen.

天文学家发现了我们所见过的最大的爆炸。

They spotted the remnants of this blast in a distant galaxy, using some of the most powerful telescopes we have, including NASA’s Chandra X-ray Observatory and the Murchison Widefield Array in Australia.

他们在遥远的星系中发现了这次爆炸的残留物，使用了我们拥有的一些最强大的望远镜，包括NASA的钱德拉X射线天文台和澳大利亚的Murchison Widefield阵列。

The observations revealed a strange void at the centre of a huge galaxy about 390 million light years away in the Ophiuchus galaxy cluster.

这些观测揭示了蛇夫座星系团中一个巨大星系中心的一个奇怪的空洞，这个星系距离我们大约3.9亿光年。

The space inside that void is seething with radio waves, which come from electrons accelerated almost to the speed of light.

这个空洞内的空间充满了无线电波，这些无线电波来自于几乎以光速加速的电子。

The researchers concluded that those electrons were accelerated by a huge explosion from just near a black hole, which smashed away all the gas in the area to leave behind just a void filled with electrons and radiation.

研究人员得出结论，这些电子是由黑洞附近的巨大爆炸加速的，它粉碎了该区域的所有气体，留下的只是一个充满电子和辐射的空洞。

The explosion released five times more energy than the previous record holder.

这次爆炸释放的能量是之前记录保持者的五倍。

“You could fit fifteen Milky Way galaxies in a row into the crater this eruption punched into the cluster’s hot gas,” Simona Giacintucci at the US Naval Research Laboratory, who was part of the team that found the explosion, said in a press release.
