极光的

Also there is a 1960's featurette included on the northern lights that is enjoyable too.

并且还有一部20世纪60年代描绘北极的短片，也很有观赏性。

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

所谓极辐射，噪声是由太阳微粒产生，而这些微粒又产生大气底的极。

: 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.

在北极圈范围，月夜下除了能够看到天上明亮的，幻莫测的极往往在夜�上著演一幕又一幕的天文表演。
