流星一直从双子座流出。这是意料之中的，因为12月中旬是双子座流星雨的时间。这张照片是周六清晨在波兰的一片白雪皑皑的森林里连续几个小时拍摄的，其中有二十多颗流星。这些转瞬即逝的条纹足够明亮，可以在右上方近乎满月的嘈杂声中看到。这些条纹都可以追溯到天空中一个被称为辐射的点，指向图像中心的亮星波鲁克斯和卡斯特。双子座流星最初是3200号小行星法厄同在其椭圆形轨道上穿过内太阳系时喷出的沙子大小的碎片。拼图挑战：当天的天文学难题

Meteors have been flowing out from the constellation Gemini. This was expected, as mid-December is the time of the Geminid Meteor Shower. Pictured here, over two dozen meteors were caught in successively added exposures taken over several hours early Saturday morning from a snowy forest in Poland. The fleeting streaks were bright enough to be seen over the din of the nearly full Moon on the upper right. These streaks can all be traced back to a point on the sky called the radiant toward the bright stars Pollux and Castor in the image center. The Geminid meteors started as sand sized bits expelled from asteroid 3200 Phaethon during its elliptical orbit through the inner Solar System. Jigsaw Challenge: Astronomy Puzzle of the Day
