有那么一瞬间，这颗明亮的火球流星在地球的夜晚比木星还亮。这张偶然的照片是在12月14日双子座流星雨高峰附近，在加拿大寒冷的天空下用延时模式相机捕捉流星时拍摄的。双子座流星雨，3200号小行星法厄同的年度礼物，总是在12月到来。这颗神秘小行星的轨道上散落的尘埃造成了流星条纹，因为蒸发的颗粒以每秒22公里的速度穿过我们美丽星球的高层大气。当然，双子座流星雨似乎是从双子星座的某个点辐射出来的。它在这个框架的左边和下面。明亮的木星在右边，在十二月的夜空中还有昴宿星团和毕宿星团。

For a brief moment, this brilliant fireball meteor outshone Jupiter in planet Earth's night. The serendipitous image was captured while hunting meteors under cold Canadian skies with a camera in timelapse mode on December 14, near the peak of the Geminid meteor shower. The Geminid meteor shower, asteroid 3200 Phaethon's annual gift, always arrives in December. Dust shed along the orbit of the mysterious asteroid causes the meteor streaks, as the vaporizing grains plow through our fair planet's upper atmosphere at 22 kilometers per second. Of course Geminid shower meteors appear to radiate from a point in the constellation of the Twins. That's below and left of this frame. With bright Jupiter on the right, also in the December night skyview are the Pleiades and Hyades star clusters.
