美国科学家在过去14个月中对浩瀚的宇宙进行了30多万亿次的监听探测,截收到了1.1亿个无线电信号.但这其中只有164个信号还值得作进一步研究,从中搜寻外空可能存在智慧生命的迹像.据报道,60年代以来,全世界的科学家进行了几十次搜索,希望能够截收到其他星球上“外星人”无线电广播或雷达发出的信号.从1980年开始,加利福尼亚大学伯克利分校着手实施一项有史以来最广泛的太空搜索.这一耗资40万美元的计划使用安装在波多黎各岛上、迄今为止功率最大、灵敏度最高的射电望远镜作为探测手段,利用其300米宽天线覆盖了安装地上空86%的天际,相当于地球之外整个天空的28%.
In the past 14 months, U.S. scientists conducted more than 30 trillion snooping surveys of the vast universe and intercepted 110 million radio signals, but only 164 of these signals deserve further study to search for the possibility that outer space may There are signs of intelligent life.Research scientists from around the world have reportedly carried out dozens of searches since the 1960s in the hope of intercepting signals from “alien” radio or other radios on other planets. , The University of California, Berkeley, is set to embark on one of the most extensive space searches ever undertaken in the $ 400,000 program using its most powerful and sensitive radio telescope on the island of Puerto Rico as its probe, using its 300-meter The wide antenna covers the sky above 86% installed, equivalent to 28% of the sky outside the Earth.
