Comet G3 ATLAS Setting over a Chilean Hill

Explanation: Where is Comet ATLAS going? In the featured time-lapse video, the comet is not itself moving very much, but the Earth’s rotation makes it appear to be setting over a hill. The Comet C/2024 G3 (ATLAS) sequence was captured with an ordinary camera on January 22 from the Araucanía Region in central Chile. Comet ATLAS has been an impressive site in the evening skies of Earth‘s Southern Hemisphere over the past few weeks, so bright and awe-inspiring that it may eventually become known as the Great Comet of 2025. Unfortunately, Comet G3 ATLAS is not going anywhere anymore because its central nucleus broke up during its close pass to the Sun last month. Some of the comet’s scattered remains of rocks and ice will continue to orbit the Sun, some in nearly the same outward section of the orbit that the comet’s nucleus would have taken.

智利山丘上空西落的阿特拉斯彗星

说明: 阿特拉斯彗星要前往何方？在这部缩时影片里，彗星本身只移动少许，但地球的自转让它看似落向山丘后方。这组阿特拉斯彗星（C/2024 G3 ATLAS）的序列影像，是在1月22日用普通的相机摄于智利中部的阿劳卡尼亚大区。在过去几星期里，阿特拉斯彗星一直是地球 南半球夜空中令人赞叹的壮丽景观，其亮度与壮观的程度，有机会为它博得2025年大彗星的美誉。然而很遗憾的是，阿特拉斯彗星可能那里也去不了，因为其彗核已在上个月接近太阳时发生崩解。尽管如此，彗星散落的部分岩石与冰屑残骸，会持续绕行太阳，有些甚至沿着原先彗核远离的轨道前行。
