Fast radio bursts: Scientists hear ‘huge’,mysterious and repeating signal from deep in space 快速无线电波：科学家听见来自太空深处响声巨大、神秘且不断重复的信号 Astronomersaren’t sure what is causing the mysterious sounds, only 17 of which have everbeen heard 天文学家并不确定是什么导致了这一神秘的声音，这样的响声从以前到现在总共才出现了17次。  Arecibo Observatory in Puerto Rico, whichsimultaneously observes the same targets, simulating a telescope more than6,800 miles in diameter NAIC - Arecibo Observatory, a facility of the NSF 在波多黎各阿雷西博天文台，他们模仿一个直径超过6800英里的望远镜，同时观察同一个目标。NAIC——阿雷西博天文台，属于NSF的设施。 Scientists have heard a long, repeatedsound from deep in space — and nobody is sure where it is coming from. 科学家们听到了从太空深处传来的悠长且重复的声音——而且没有人能确定这个声音是从哪里冒出来的。 Astronomers found 10 millisecond-long“fast radio bursts”, the latest example of a mysterious radio wave coming fromoutside of our galaxy. 天文学家们发现了长达10毫秒的“快速无线电脉冲”，最新发现的这一神秘的无线电波是来自于我们的银河系之外的。 Scientists had previously thought thatthe bursts were singular events. But a new study finds that at least some ofthe sources send out repeated messages. 科学家们早先曾认为这些突发的响声只是单一事件。但是一项新的研究发现这些声源中至少有一部分是一直在发送重复的讯息。 The finding adds to other strangediscoveries about the fast radio bursts that seem to indicate that there may besomething unusual causing them. Scientists said last year that some of themessages appear to be coming in a pattern — one that could even be created byalien technology. 还发现了一些其他关于快速无线电突发消息的奇怪现象，这些现象似乎都表明可能是由于一些不寻常的东西引起的。科学家们说自去年起，其中一些消息开始进入了一个模式——这种模式甚至有可能是由外星技术引起的。 The new research sheds little new lighton what exactly is causing the messages. But it does offer perplexing questionsabout what sort of source could be emitting them. 这项新的研究并未能完全解释出究竟是什么导致了这种消息的产生。但是它的确提出了一个令人费解的问题，那就是释放出这种消息的源头究竟是什么。 “"We're showing that whateverbattery drives FRBs, it can recharge in minutes," said James Cordes, anastronomy professor at Cornell University, in astatement. “我们所展示出来的是，不管这些快速无线电脉冲是受什么样的电池驱动，这个电池可以在几分钟之内就充好电，”康奈尔大学天文学教授James Cordes,，在一份声明中说道。 "The energy of the event becomesvery problematic. We're detecting these FRBs from very far away, which meansthat they are intrinsically very bright. Only a few astrophysical sources canproduce bursts like this, and we think they are most likely neutron stars inother galaxies." “该事件的能量来源问题变得非常困难。我们是从很远的地方侦探到这些快速无线电脉冲的，这也就意味着本质上而言，它们的声音是非常大的。只有几个天体可以发出这样的突发声，而且我们认为它们很有可能是其他星系的中子星。” Previously, scientists had thought thatmessage was coming from something like the collision of neutron stars, sendinga shockwave of energy across the universe. But the new findings show that thesource of the energy isn’t being destroyed, since they send out more than oneburst. 之前，科学家们认为是由于中子星之间的碰撞，在宇宙中发出了冲击波，才产生了这一讯息的。但是该新发现显示，这一能量的来源是没有被损坏的，因为他们发出的并不只是一个突发讯息。 "In our paper, we're showing thatour FRB can't have an explosive origin,” said Shami Chatterjee, a senior researcher at Cornell, in a statement. “So, either there's an oddcoincidence, or maybe there are different types of FRBs. “在我们的报告中，我们展示出了我们收到的快速无线电脉冲是不可能有一个爆炸性来源的，”Shami Chatterjee——康奈尔大学的一位高级研究员，在一份声明中说道。“所以，要么就是有这样一个奇怪的巧合，要么就是存在有不同类型的快速无线电脉冲。” “Either way, it seems we've broken thisenigmatic phenomenon wide open." “不管是哪一种，我们似乎都已经开启了这一神秘现象了。” 评论 You just know it's the signature tune of The Archers from another constellation. Probably Sagittarius. 你只知道那是来自另一个星群的射手的音调。可能是射手座吧。 glyn thompson Try Central Office I expect. 试着联系一下中心局吧，我觉得。 16 days ago Turnpike The message says "There will be consequences if you vote to leave the EU". 该讯息说的是“如果你投票离开欧盟的话，那是要承担后果的。” 16 days ago IraqIran_n_Stan Wrong number? 打错电话了？ 16 days ago QuantumEffectsRule Is it the front line getting closer? 是离前线越来越近了么？ 16 days ago Steve Hill The *nearest* galaxy to our own, Andromeda, is 2.5 million light years away. So I'm not going to worry yet. Andromeda，离我们“最近的”星系，也有250万光年的距离。所以我现在还不会担心。 12 days ago Dharmesh Forget the nearest galaxy, the nearest star is only 4.2 light years away and if there is an advanced life there, it won;t take much time for them to find us ;) 先别说那最近的星系吧，离我们最近的恒星只有4.2光年的距离，如果那里有高级生命的话，那他们要找到我们的话，是花不了多长时间的。;) 12 days ago Steve Hill As the article makes clear, the "noise" is probably caused by a neutron star in another galaxy. If it was that close in our own galaxy, we'd know about it! (Possibly only for the next few milliseconds). 正如这篇文章中表明的，该“噪声”很可能是由另一个星系的中子星引起的。 如果那离我们的星系真那么近，那我们肯定会知道的！（可能就在接下来的几毫秒里）。 16 days ago criticalreader Strange, very strange...maybe it was this: https://www./watch?v=OOP-FQLf0Cs Remember that any reply will take light years to get back to the source, if indeed we are dealing with aliens... 奇怪，非常奇怪……也许是这个吧：https://www./watch?v=OOP-FQLf0Cs 记住任何答复都将会使光年回到源头上，如果真是这样的话，那正和我们打交道的就是外星人。 16 days ago roger If the signals were of 'intelligent' origin then the vast distances involved means that they're all dead now. 如果该信号是“智能”的起源，再考虑到所涉及的遥远距离，那这就意味着他们现在都已经死了。 16 days ago Rev.

I hope they've checked better this time. 上一次，他们说在上午九点时，听到了一些有希望是外星人的声音，结果在中午12点的时候，发现原来是受到了正在加热科学家们的馅饼的微波炉的干扰。我希望他们这次可以做出更好的检查。 16 days ago Mr Paxton They should just get one of those mini tabletop ovens so the pies come out nice and crispy like a good pie should! Besides, ET doesn't want soggy pies. 他们就应该买个迷你桌面烤箱，这样那些馅饼才能烤得又好又脆，就像是一个脆饼该有的样子！ 而且，外星人也不想吃湿湿的、不脆的馅饼。 16 days ago Christopher Searle Erm.... Messages?
