Called Auroral Kilometric Radiation (AKR), the noise is generated by the same shaft of solar particles that produces an aurora in the atmosphere below.

所谓光千米辐射，噪声是由太阳微粒产生，而这些微粒又产生大气底层的光。

: In polar region, apart from the bright stars seen under moon night, ever changing aurorae are making scenes after scenes of celestial display in the darkness.

在范围，月夜下除了能够看到天上明亮的星外，变幻莫测的光往往在夜�上著演一幕又一幕的天文表演。
