#太平洋电脑网#什么鬼：我们已知的最怪异恒星的故事( 六 )


If the model is anything to go by, thesupergiant planet will have an orbital period of 12 years. And as thingscurrently stand, those interested can expect to see the effect of trojans(assuming they’re there) on the light from Tabby’s star in 2021, followed bythat of the planet itself two years later.
如果这个模型能够成立 ， 那么这颗巨型行星的轨道周期应该是12年 。 根据现有的假说 ， 人们应该能在2021年观测到木马（如果它们存在的话）对塔比星亮度产生的干扰 ， 再过两年将能够看到行星产生的干扰 。
The idea of a ringed planet is particularlycaptivating to scientists, it seems. Another pre-print paper earlier this month made the same claim:maybe a planet with rings can explain the phenomenon…
看起来这个有环行星的概念格外吸引科学家 。 另一篇本月初刊登的预发表论文给出了相同的论断：或许一个有环行星可以解释这种现象……
However, a ringed planet would stillprovide a consistent dimming pattern – something we haven’t yet seen.
然而 ， 即使一颗有环行星仍然可以提供一种稳定的干扰模式——但是我们并未观测到这一模式 。
Starting late 2015, the SETI Institutebegan looking for signs of extraterrestrial intelligence from the direction ofTabby’s star. Specifically, the institute pointed the Allen Telescope Array inCalifornia in the star’s general direction hoping to pick up on radio wavesencoded with information that would betray the hand of an alien intelligence.The odds of actually picking up on a signal were poor. Tabby’s star is 1,500lightyears away. Anything we detect now should’ve been emitted that many yearsago. Moreover, if the Tabbians were an advanced civilisation, beaming radiosignals into arbitrary patches of sky wouldn’t have made much sense. Theywould’ve observed us first and then sent out something intended specificallyfor us – a 3,000-year process because that’s how long radiation would take totravel back and forth.
从2015年末开始 ， SETI研究所开始在塔比星方向搜寻地外智慧生命的迹象 。 该研究所特别使用位于加州的艾伦望远镜阵列指向该恒星的大致方位 ， 希望能够捕捉到外星智慧生命手中泄露出来的包含信息的无线电波 。 但是捕获类似信号的机会微乎其微 。 塔比星位于1500光年以外 。 我们现在探测到的任何信息都是许多年前发送出来的 。 另外 ， 如果塔比星人真的是某种智慧生命 ， 他们也不大会随便对着天空某个部分发射电波 。 他们应该会先发现我们 ， 然后专门对我们发送出什么消息——无线电波走一个来回的时间是3000年 。
Three-thousand years ago – i.e. in 985 BC –the Mauryas were ruling over most of India, and both Confucianism and Hellenismwere just starting to develop. If at all these beings were able to detect lifeon our planet, they would have observed us in the Iron Age. First, they’d havehad to calculate how long we would take to become proficient at detecting radiosignals, then they’d have to beam signals at us for years together so that oneday, someday, we’d finally turn our telescopic ears in their direction.Essentially, the chances are too low.
3000年前——比如公元前985年 ， 孔雀王朝正统治着大部分印度领土 ， 儒家思想和希腊化刚刚开始发展 。 如果这些外星人发现我们的星球上有智慧生命 ， 他们应该会发现我们还处在铁器时代 。 首先 ， 他们应该会计算出还有多久我们才能学会探测无线电信号 ， 然后他们会持续好几年对着我们发送无线电波 ， 这样到某一天我们开启天线对着他们的方向时 ， 我们就能收到信号了 。 说实话 ， 这种机会少到不能再少了 。
