Explanation: Comet NEOWISE has been wowing photographers around much of the world during dawn and dusk, at the margins of day and night. For the most northern residents of planet Earth, however, the comet circles the North Star and never sets. The night part of this circular arc is apparent in the featured composite of images assembled from a webcam located at a ski resort in the Swiss Alps. Images were selected at 30-minute intervals throughout the night from July 12th -13th. Comet NEOWISE (C/2020 F3) will continue to become more accessible to northern hemisphere observers as its motion places it higher in the sky each evening after sunset over the next few weeks, as it begins its outbound journey. As with all comets, departure from the inner Solar System comes with inevitable fading. Binoculars are the best way to find and observe the comet visually.

说明:低徊在落日后或破晓前天空NEOWISE彗星,吸引了世界各地的摄影者拍照。对地球北半球的住民来说,目前这颗彗星旋绕着北极星并且彻夜可见。在这幅组合自瑞士阿尔卑斯山滑场的网络相机照片之主题影像里,摄于夜晚时段的弧状拱极彗星身影清楚可辨。组成夜间时段影像、间隔30分钟的照片,则是摄于7月12日-13日那晚。而随着NEOWISE彗星(C/2020 F3)踏上归程,在接下来的数星期,它会持续往天空攀升,所以对北半球的观星者来说越来越容易观测。不过就像其他彗星一样,远离太阳系内围意味着它必然会变暗,因此使用双筒望远镜有助于寻找和观赏这颗彗星。
