说明: 在12月11日从月球后方返回地球之时，猎户号太空船以接近每秒11公里的速度切入地球的大气层。而这个速度，则是在12月13日双子流星雨极大期附近，曳出这道颀长火流星迹的尘埃微粒，穿过大气层的速度之半。当我们美丽的地球每年穿过神秘的小行星3200 Phaethon（法厄同）的尘埃尾流时，所产生的双子流星之平行迹线，皆看似辐散自双子座内的辐射点。不过，在这幅摄于中国．云南省美丽的蓝月谷的夜空影像里，双子座的双子星隐藏在左侧绿树的后方。此外，在山湖平静湖面的中心附近，可见到倒映的东升猎户座群星。而在这片星空里，耀眼的火星依旧是其中最明亮的天体明灯。

Explanation: Returning frombeyond the Moon, onDecember 11the Orion spacecraft entered Earth's atmosphereat almost 11 kilometers per second.That's half the speed of the grain of dust that created this longfireball meteor when it entered the atmosphere on December 13,near the peak of the annualGeminid meteor shower.As our fair planet makes its yearly pass through the dust trail of mysteriousasteroid 3200 Phaethon,the parallel tracks of all Geminid meteors appearto radiate from a point in the constellation Gemini.But the twin starsof Gemini hide just behind the trees on theleft in this night skyscapefrom the beautiful Blue Moon Valley, Yunnan, China.Reflected in the still waters of the mountain lake, stars ofthe constellation Orion are rising near center.Captured before moonrise,dazzling Marsis still the brightest celestial beacon in the scene.
