#太平洋电脑网#什么鬼：我们已知的最怪异恒星的故事( 七 )


The Allen array didn’t detect anythingduring its observations. Astronomers at SETI also were on the lookout for radiosignals. A smaller effort even looked forflashes of lasers from around the star.
艾伦望远镜阵列没有观察到任何东西 。 SETI的天文学家们也在寻找无线电信号 。 还有个更小的努力是从那颗恒星的区域寻找激光的闪耀 。
Nothing.
一无所获 。

In all this time, Tabby’s Star has beensteadily dimming, with nothing blocking its light as far as we can tell. It’sfading away and we have no idea why.
塔比星正在持续变暗 ， 而到目前为止我们并没发现有什么东西遮挡住了它 。 它在逐渐淡出 ， 我们并不知道原因 。
Monitoring it round-the-clock is importantif only because astronomers can pick up on the smallest clues. But for thispurpose, government-run telescopes are usually overbooked. Even if they wereavailable, their administrators don’t prefer taking on long-term observations.So Boyajian and her team have turned to private observatories – like the LasCumbres Observatory Global Telescope (LCOGT) Network. Its scopes areplaced strategically across the globe soastronomers can use them to look at an obxt (in the sky, not across the road)24×7. And to pay for using them for a year, Boyajian raised $107,421 througha Kickstarter campaign inMay 2016.
如果只是因为天文学家能够捕捉到最小的线索 ， 那么24小时不间断观测是很重要的 。 但是这经常导致政府运行的望远镜被超额预定 。 即使有空缺 ， 望远镜的管理者们也不愿意进行长期观测 。 所以Boyajian和她的团队转向了私人天文台——例如拉斯卡姆博斯天文台全球望远镜（LCOGT）网络 。 它的望远镜战略性地布满全球 ， 使得天文学家可以用它们全时观测一个物体（在天上的 ， 不是马路对面的） 。 为了支付一年的使用金 ， Boyajian在2016年5月举办的一次起步者大会上筹得了107421美元 。
Fast forward to 2017.
时间很快到了2017年 。
All the attention has brought together acommunity of amateur and professional astronomers who are constantly observing,working on and thinking about Tabby’s star. The smallest of fluctuations in itsbrightness is meticulously recorded and shared.
集合了一群业余和专业天文学家 。 他们一直在观察、研究和思索塔比星之谜 。 最微小的亮度波动都会被仔细记录下来并分享 。
On April 24, an alx went out from arobotic telescope at the Fairborn Observatory, Arizona, after it noticed a dipin the star’s brightness. It was a perfectly normal statistical fluctuation andthe brightness returned to its former level in a week. But astronomers weren’t– aren’t – risking any complacency. Eternal vigilance is the official partyline.
在4月24日 ， 亚利桑那州的费尔鲍恩天文台的一台机器人望远镜发出警报 ， 它观测到塔比星出现亮度干扰 。 这是一次完美的正常波动 ， 其亮度在一周后恢复正常 。 但是天文学家们没有自满 。 永远保持警醒是他们的行业底线 。
A similar event occurred on May 14 at theMercator Telescope in Spain. Scientists there promptly contacted Boyajian, butthe data she was shown sported just another statistical variation. “In the end,it ended up being an artefact – i.e. not real,” she told The Wire.
