Explanation: It was one of the better skies of this long night. In parts of Antarctica, not only is it winter, but the Sun can spend weeks below the horizon. At China‘s Zhongshan Station, people sometimes venture out into the cold to photograph a spectacular night sky. The featured image from one such outing was taken in mid-July of 2015, just before the end of this polar night. Pointing up, the wide angle lens captured not only the ground at the bottom, but at the top as well. In the foreground, a colleague is taking pictures. In the distance, a spherical satellite receiver and several windmills are visible. Numerous stars dot the night sky, including Sirius and Canopus. Far in the background, stretching overhead from horizon to horizon, is the central band of our Milky Way Galaxy. Even further in the distance, visible as extended smudges near the top, are the Large and Small Magellanic Clouds, satellite galaxies near our huge Milky Way Galaxy.

说明: 它是那个漫漫长夜较出采的天空景观之一。在该时的南极洲某些地区，不但时值寒冬，太阳更是连续数星期都未曾冒头。然而在中国的南极中山站，人们有时会顶着酷寒出门拍摄精采的夜空。这幅主题影像，即是在2015年7月中旬南极夜行将结束时，某次冒险出门之所得。当时上指的广角镜头，不但记录了下方的地面，更捕捉到影像顶端另一侧地面的景观。影像的前景有正在拍照的同事，远处有球形的卫星接收器和数座风车。而夜空则散布着点点繁星，其中包括天狼星和老人星。在远方的背景里，从地平线伸展到另一侧地平线的，是我们银河系的中央盘面。而在头顶附近的更遥远后方，可见到以弥漫光斑之姿现身的大与小麦哲伦星系，这二个邻近我们庞大银河系的伴星系。
