在中国中北部干旱的腾格里沙漠，地球占据了这片星空的前景。这张广角全景照片是在12月14日当地黎明前的月落后不久拍摄的。在静止的黑暗天空中，北方冬季六边形的星星围绕着明亮的银河系。在一年一度的流星雨的高峰期附近，一颗明亮的双子座火球流星的惊人闪光也在当晚被捕捉到。在西方地平线上，就在明亮的卡佩拉星的下方，它的匕首状轨迹指向双子座流星雨的光芒。当然，双子座很容易被发现。它的两颗明亮的恒星，淡蓝色的蓖麻星和淡黄色的波吕星在画面的上方中心附近。

An arid expanse of the Tengger Desert in north-central China, planet Earth fills the foreground of this starry scene. A widefield panoramic view, it was recorded shortly after moonset in the local predawn hours of December 14. Pictured in the still dark sky, stars of the northern winter hexagon surround a luminous Milky Way. Seen near the peak of the annual meteor shower, the startling flash of a bright Geminid fireball meteor was also captured on that night. Above the western horizon and just below bright star Capella, its dagger-like trail points back to the meteor shower's radiant in Gemini. Of course, the constellation Gemini is easy to spot. Its twin bright stars, bluish Castor and yellowish Pollux are near top center in the frame.
