一顆明亮的彗星正在向傍晚的天空移動。C/ 2023 A 3 （Tsuchinshan-ATLAS）彗星已經變亮，儘管它現在很容易被肉眼看到，但它離太陽很近，仍然很難看到。圖中，津欽山-ATLAS 彗星是日出前從秘魯安第斯山脈拍攝到的。天文攝影師冒著寒冷的天氣，站在這個異常高的地方，東方的地平線非常低，彗星在黎明前的天空中非常明顯。 在這張特寫圖片中，我們不僅可以看到一條長長的塵埃尾，而且還可以看到一條長長的藍色離子尾。 本月，當彗星遠離太陽並與地球擦肩而過時，傍晚的觀測者應該能在日落後看到這個巨大的骯髒冰球向西移動。 成長相簿： 2024 年的月山-ATLAS 彗星
原文：A bright comet is moving into the evening skies. C/2023 A3 (Tsuchinshan–ATLAS) has brightened and even though it is now easily visible to the unaided eye, it is so near to the Sun that it is still difficult to see. Pictured, Comet Tsuchinshan–ATLAS was captured just before sunrise from an Andes Mountain in Peru. Braving cold weather, this unusually high perch gave the astrophotographer such a low eastern horizon that the comet was obvious in the pre-dawn sky. Visible in the featured image is not only an impressively long dust tail extending over many degrees, but an impressively long and blue ion tail, too. This month, as the comet moves out from the Sun and passes the Earth, evening observers should be able to see the huge dirty ice ball toward the west just after sunset.
