月神山-ATLAS 彗星現在在清晨的天空中清晰可見。 這座骯髒的大冰山以奇特的角度潛入太陽系內部，將在兩天內透過離太陽最近的位置--水星和金星的軌道之間。相機的長時間曝光正在捕捉日出前和日出期間的 C/ 2023 A 3 （Tsuchinshan-ATLAS）（有時簡稱為 A 3 ）及其塵埃尾跡。 這張照片是四天前拍攝的，捕捉到了彗星在澳大利亞新南威爾士州喬治湖上空升起的過程。 左側的垂直條帶是彗星的影像，當時太陽正在升起，黎明前的天空變得越來越明亮多彩。彗星在接下來的一個月裡會變得多亮，目前還不得而知，因為這涉及到彗核會排出多少氣體和塵埃。樂觀的觀天者們希望看到一場精彩的表演，讓一山-ATLAS 創造出地球天空可見的塵埃和離子尾巴，並被稱為 2024 年的大彗星。 調查：色盲與天文影像成長相簿： 2024 年的月神山-ATLAS 彗星
原文：Comet Tsuchinshan-ATLAS is now visible in the early morning sky. Diving into the inner Solar System at an odd angle, this large dirty iceberg will pass its closest to the Sun -- between the orbits of Mercury and Venus -- in just two days. Long camera exposures are now capturing C/2023 A3 (Tsuchinshan–ATLAS), sometimes abbreviated as just A3, and its dust tail before and during sunrise. The featured image composite was taken four days ago and captured the comet as it rose above Lake George, NSW, Australia. Vertical bands further left are images of the comet as the rising Sun made the predawn sky increasingly bright and colorful. Just how bright the comet will become over the next month is currently unknown as it involves how much gas and dust the comet's nucleus will expel. Optimistic skywatchers are hoping for a great show where Tsuchinshan–ATLAS creates dust and ion tails visible across Earth's sky and becomes known as the Great Comet of 2024.
