中国的望远镜没有发现外星信号。搜索仍在继续。

A Chinese Telescope Did Not Find an Alien Signal. The Search Continues.

Word flashed around the world that Chinese astronomers had detected a radio signal that had the characteristics of being from an extraterrestrial civilization — namely, it had a very narrow bandwidth at a frequency of 140.604 MHz, a precision nature doesn’t usually achieve on its own.

世界各地都有消息称,中国天文学家探测到一个具有外星文明特征的无线电信号——也就是说,它的带宽非常窄,频率为140.604兆赫兹(MHz),这种精度通常是自然本身无法达到的。

They made the detection using a giant new telescope called the Five-hundred-meter Aperture Spherical radio Telescope, or FAST. The telescope was pointed in the direction of an exoplanet named Kepler 438 b, a rocky planet about 1.5 times the size of Earth that orbits in the so-called habitable zone of Kepler 438, a red dwarf star hundreds of light years from here, in the constellation Lyra. It has an estimated surface temperature of 37 degrees Fahrenheit, making it a candidate to harbor life.

我们使用FAST进行了探测。望远镜指向的是一颗名为开普勒438 b的系外行星,这是一颗岩石行星,大小约为地球的1.5倍,其轨道位于所谓的开普勒438宜居区,开普勒438是天琴座数百光年外的一颗红矮星。据估计,它的表面温度为37华氏度,是孕育生命的理想地区。

Just as quickly, however, an article in the state-run newspaper “Science and Technology Daily” reporting the discovery vanished. And Chinese astronomers were pouring cold water on the result.

然而,官方报纸《科技日报》报道这一发现的一篇文章也很快消失了。而中国天文学家正在为这一结果泼冷水。

Zhang Tong-jie, the chief scientist of China ET Civilization Research Group, was quoted by Andrew Jones, a journalist who tracks Chinese space and astronomy developments, as saying, “The possibility that the suspicious signal is some kind of radio interference is also very high, and it needs to be further confirmed or ruled out. This may be a long process.”

追踪中国太空和天文学发展的记者安德鲁·琼斯引用中国ET文明研究小组首席科学家张通杰的话说:“可疑信号是某种无线电干扰的可能性也很高,需要进一步确认或排除。这可能是一个漫长的过程。”
