 Is 'Oumuamua an alien spacecraft? Initial scans show no signs of technology 奥陌陌是外星人飞船吗？ 最初扫描结果显示没有外星科技的征兆 An artist’s impression of the ‘Oumuamua asteroid, which scientists are scanning for signs of intelligent life.

The body is twice as far from Earth as the sun, but the telescope is so sensitive it could detect transmissions as weak as those produced by a mobile phone. 由互联网亿万富翁Yuri Milner资助的“突破探听计划”的科学家们, 使用在西弗吉尼亚州的绿岸天文望远镜，探测到了这个400米长的、被命名为“Oumuamua”物体。这个名字是夏威夷语“信使”或“侦察员”的意思。它与地球的距离是地球离太阳的两倍，但望远镜是如此敏感，它可以检测到像移动电话产生的那么弱的信号。 scout：侦查者 eavesdrop： 偷听 But on Thursday, the astronomers declared that the first observations across four bands of the radio spectrum had found no evidence that ‘Oumuamua is anything other than a long lump of space rock. Scientists on the project have released the data from the observations so anyone can study the information. 但在星期四，天文学家宣布，在四波段的无线电频谱的第一次观测中发现奥陌陌只不过是一个长块的太空石头。该项目的科学家已经发布了这些观测数据，任何人都可以研究这些信息。 “This is a fishing expedition,” said Avi Loeb, professor of astronomy at Harvard University and an adviser to the Breakthrough Listen project. “We are most likely not to find anything, but it is worth checking steadily our fishing hooks. We will keep searching for artificial signals from ‘Oumuamua or any other interstellar object that will be discovered in the future.” "这是一次试探性调查," 哈佛大学天文学教授、“突破探听计划”的顾问 Avi Loeb说。”我们很可能不会发现任何东西，但却是对于我们鱼钩来说，是值得检验一下的。我们将继续从奥陌陌、或任何将来可能发现的星际物体上，寻找人工信号。 The first batch of four observations ran from 8.45pm UK time on Wednesday until 2.45am on Thursday morning and spanned a frequency range from 1 to 12 GHz. While the search for alien signals has so far found nothing in the 1.7 to 2.6GHz range，the rest of the data is still being processed. 第一批的四个观测是从英国时间的周三的8.45pm一直到星期四早晨的2.45am。搜索的频率范围从1到12GHz。虽然搜索外星信号到目前为止在1.7到2.6GHz范围内一无所获，其余的数据仍在处理中。 The interstellar asteroid was first spotted by researchers on the Pan-Starrs telescope project in Hawaii as it swept past Earth at 85 times the distance to the moon. As ‘Oumuamua sped towards the sun, it gathered speed, reaching 196,000mph. The body is moving so fast it will eventually leave the solar system completely. 在夏威夷的泛星计划的研究人员首次发现了这颗星际小行星, 它在距地球约85倍于地月距离飞过时被发现。随着 Oumuamua 加速向太阳行驶, 它聚集速度达到196,000mph。这个物体移动得这么快, 最终它会完全离开太阳系。 asteroid: 小行星
