…From physical and astronomical considerations, P. Morrison and G. Cocconi thought that such intelligence was communicating into space at wavelengths close to the 21 cm (1420 MHz) hydrogen line. In 1960, F.D. Drake of the National Radio Astronomy Observatory of the United States followed this idea and observed the solar-like stars Tau Ceti and ε Eridanus, which are relatively close to the Sun, for a total of 150 hours over a period of two months. He named this project Project Ozma after the princess of the Land of Oz in the fairy tale by LF Baum (1856-1919). … *Some of the terminology that mentions "Drake, FD" is listed below.

…物理学的・天文学的考察から,このような知性は,波長21cm(周波数1420MHz)の水素線の近傍の波長で宇宙空間へ向けて通信を行っているとモリソンP.MorrisonとココーニG.Cocconiは考えた。1960年,アメリカ国立電波天文台のドレークF.D.Drakeは,この考えに従って太陽の比較的近傍にあって,太陽類似の,くじら座τ星とエリダヌス座ε星を2ヵ月にわたって延べ150時間あまり観測した。彼はボームL.F.Baum(1856‐1919)のおとぎ話に出てくるオズの国の王女の名をとってこの計画をオズマ計画と名付けた。… ※「Drake,F.D.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
