Explanation: 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.

说明: 在这片星空景观里，前景是位在地球．中国北方的荒芜无垠的腾格里沙漠。这幅大视野的全景影像，摄于当地甫月落后的日出前时分。在当时仍然很黝黑的天空中，组成北天冬季六边形的亮星环拱着明亮的银河。拍照的时间点则选在双子流星雨的极大期附近，因此影像也记录了一颗无比明亮的火流星。这颗闪现在西方地平线上空、亮星五车二下方的流星，其匕首状的流星痕回指位在双子座之内的辐射点。双子座不难辨认，其内的双子星、泛蓝的北河二和泛黄的北河三，高悬在影像的顶缘中心附近。
