Explanation: What are those bright lights in the sky ahead? When hiking a high mountain pass in northern Italy three weeks ago, a conjunction between our Moon and the distant planet Jupiter was visible as both rose together in the southwest after sunset. The picturesque mountains in the distance are Tre Cime di Lavaredo (Three Peaks of Lavaredo), a UNESCO World Heritage Site and three of the best known mountain peaks in Italy, the Dolomites, and the entire Alps. In the foreground on the left is Locatelli Hut, a refuge for tired hikers as it is located over an hour from nearest parking lot. The bright sky object on the upper left is Saturn. The entire scene was captured on a single 8-second exposure. Jupiter and Saturn will remain prominent in the western sky after sunset this month, while the Moon, in its monthly orbit around the Earth, will pass near Jupiter again in about four days.

说明:前方天空中那些明亮的灯光是什么?三周前,当我在意大利北部的一个高山隘口徒步旅行时,看到了日落后在西南方同时升起的木星合月。远处风景如画的山脉是联合国教科文组织世界遗产地-拉瓦雷多三尖峰,那是意大利最著名的三座山峰,白云石山脉和整个阿尔卑斯山脉。影像左侧前景中的是洛卡特利小屋,是一间为疲惫的徒步旅行者准备的避难所,因为它位于距离最近的停车场有超过一个小时的路程。影像左上方的明亮天体则是土星。整个场景是在时长为8秒钟的单次曝光下拍摄的。本月日落后,木星和土星将仍在西方的天空中闪耀,而每月绕地球运行一周的月球将在大约四天后再次经过木星附近。
