aurorae

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

所光千米辐射，噪是由太阳微粒产生，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.

在北圈范围，月下除了能够看到天上亮的星外，变幻莫测的光往往在�上著一幕又一幕的天文表。
