Animation: Comet Tsuchinshan-ATLAS Tails Prediction

月琴山-ATLAS 彗星的尾巴會變得多麼明亮和奇特？在過去的幾周裡，這顆彗星的亮度急劇增加，因為它越過了離太陽最近的位置，就在三天前，它還越過了離地球最近的位置。在過去幾天裡，C/ 2023 A 3 （Tsuchinshan-ATLAS）成為上個世紀最亮的彗星之一，但不幸的是，由於它幾乎與太陽重疊，所以很難看到。 隨著這顆彗星逐漸遠離太陽，它正在成為一道亮麗的風景線--但可能很快就會開始暗淡下去。 這段動畫影片展示了從地球上看彗尾的發展過程，並對彗尾的進一步發展做出了預測。如影片所示，彗星尾部塵埃較重的部分已經開始與塵埃較輕的部分以及彗星的離子尾（即被太陽風直接從太陽推出的藍色尾巴）指向幾乎相反的方向。 成長相簿： 2024 年的月山-ATLAS 彗星
原文：How bright and strange will the tails of Comet Tsuchinshan-ATLAS become? The comet has brightened dramatically over the few weeks as it passed its closest to the Sun and, just three days ago, passed its closest to the Earth. C/2023 A3 (Tsuchinshan–ATLAS) became of the brightest comets of the past century over the past few days, but was unfortunately hard to see because it was so nearly superposed on the Sun. As the comet appears to move away from the Sun, it is becoming a remarkable sight -- but may soon begin to fade. The featured animated video shows how the comet's tails have developed, as viewed from Earth, and gives one prediction about how they might further develop. As shown in the video, heavier parts of the dust tail that trails the comet have begun to appear to point in nearly the opposite direction from lighter parts of the dust tail as well as the comet's ion tail, the blue tail that is pushed directly out from the Sun by the solar wind.
