…It was observed that auroral electrons emit radio waves into space. Because the wavelength of this radio wave is on the order of kilometers (frequency = tens to hundreds of kHz), it is called auroral kilometric radiation (AKR). The discovery of AKR made it clear that the Earth, like Jupiter and Saturn, is a planet that emits radio waves into space. … *Some of the terminology that refers to "auroral kilometric radiation" is listed below.

…オーロラ電子が宇宙空間に電波を放射していることが観測されたのである。この電波の波長がkmのオーダー(周波数=数十~数百kHz)であることからオーロラ・キロメーター放射(AKR)と呼ばれている。AKRの発見で地球も,木星や土星と同じく宇宙空間に向けて電波を発射している惑星であることが明らかになった。… ※「オーロラ・キロメーター放射」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 |
