Ozma Project - Ozuma Keikaku (English)

Japanese: オズマ計画 - おずまけいかく(英語表記)Ozma Project
Ozma Project - Ozuma Keikaku (English)

This project was the starting point of attempts to communicate with highly technologically advanced aliens living on other planets through radio waves. In 1960, Frank Donald Drake attempted to receive 21-centimeter radio waves from the stars Tau Ceti and Epsilon Eridanus using a 26-meter antenna at the National Radio Astronomy Observatory in Green Bank, West Virginia (transferred to the Green Bank Observatory in 2016). The observations themselves were discontinued after 400 hours, and the reception was unsuccessful, but the project was significant in that it raised interest in radio astronomy among academics and the general public, and provided a new stimulus to the view of aliens. The name of this project, "Ozma," comes from Princess Ozma, a character in Baum's fairy tale series (such as "The Wonderful Wizard of Oz").

Japanese:

異星の惑星上に住む高度技術文明をもつ宇宙人と、地球人類とが電波で交信しようとする試みの原点となった計画。1960年、アメリカ、ウェスト・バージニア州グリーンバンクにある国立電波天文台の口径26メートルのアンテナ(2016年にグリーンバンク天文台に移管)を使って、ドレークFrank Donald Drakeが、くじら座τ(タウ)星およびエリダヌス座ε(イプシロン)星からの波長21センチメートルの電波を受信しようとした。観測そのものは400時間行われただけで打ち切られ、受信にも成功しなかったが、学界と一般社会に電波天文学への関心を高めたこと、宇宙人観に新たな刺激を与えたことなど、その意義は大きかった。なお、この計画名「オズマ」は、バウムの童話シリーズ(『オズの魔法使い』など)に登場するオズマ姫にちなんだものである。
