Explanation: Go outside at sunset tonight and see a comet! C/2023 A3 (Tsuchinshan–ATLAS) has become visible in the early evening sky in northern locations to the unaided eye. To see the comet, look west through a sky with a low horizon. If the sky is clear and dark enough, you will not even need binoculars — the faint tail of the comet should be visible just above the horizon for about an hour. Pictured, Comet Tsuchinshan-ATLAS was captured two nights ago over the Lincoln Memorial monument in Washington, DC, USA. With each passing day at sunset, the comet and its changing tail should be higher and higher in the sky, although exactly how bright and how long its tails will be can only be guessed.

说明: 今晚日落时，请走到户外去看彗星。在北半球的傍晚天空中，彗星C/2023 A3（紫金山–阿特拉斯）已经成为肉眼可见的天体。想要观赏这颗彗星，请在有低地平线的地方往西看。如果天空晴朗而且够暗，你不需要借助望远镜，即可在日落后的1小时期间，见到这颗悬在地平线上方的彗星之暗淡彗尾。这幅摄于美国华盛顿特区的影像，呈现2天前紫金山-阿特拉斯彗星在林肯纪念堂上空的身影。在接下来每天的日落时，这颗彗星及其彗尾在天空的位置会越来越高，不过，到底彗星会有多亮及彗尾会有多长，则很难说。
