雅思閱讀材料之美國啟動尋找外星人計劃
The giant dish began this week pointing toward each of the 86 planets -- culled from a list of 1,235 possible planets identified by NASA's Kepler space telescope -- and will gather 24 hours of data on each one.
The mission is part of the SETI project, which stands for Search for Extra Terrestrial Intelligence, launched in the mid 1980s.
"Our search employs the largest fully steerable radio telescope on the planet, and the most sensitive radio telescope in the world capable of undertaking a SETI search of this kind," Siemion told AFP.
美國的天文學家近日開始了一項計劃,他們將使用各種工具(天文望遠鏡之類的吧),開始有組織有規(guī)模的在地球以外的86顆行星上,尋找外星人。
這86顆星球,是NASA 開普勒望遠鏡從1235顆星球中,探測出來的最有可能的86個。
該計劃名為Search for Extra Terrestrial Intelligence/搜尋外星智能,是在1980年代提出的。一直拖到了本周才開始啟動。據說首先科學家們將監(jiān)視這86顆星球24小時,并收集相關數據。
研究人員Siemion 說:我們將使用最敏感的射線望遠鏡來收集數據,每秒就可掃描1Ggigabyte 的數據。
