你知道嗎？在浩瀚的宇宙中，曾經出現過一顆非常特別的彗星，叫做Comet Lemmon！有一次，這顆彗星在天空中展示了它最美的一面。在這幅照片裡，最先看到的是中國的梅里雪山，白雪皚皚，像是在呼喚我們去探險呢！接下來就是Comet Lemmon，它的身邊有兩條顏色不同的尾巴哦！一條白色的塵埃尾巴向右飄散，而另一條因為太陽風而變形的藍色離子尾巴則向左延伸。遠遠的地方，我們還能看到美麗的銀河系，它裡面有很多暗暗的塵埃和紅色的星雲，還有數以億計的類似太陽的星星。雖然Comet Lemmon正在漸漸消失，朝著外太陽系移去，但這些美麗的山脈將會在未來的一千萬年中慢慢被侵蝕。而我們的銀河系呢？它將繼續存在，形成新的山脈和彗星，陪伴我們走過許許多多的時間！
原文:
What did Comet Lemmon look like when it was at its best? One example is pictured here, featuring three celestial spectacles all at different distances. The closest spectacle is the snowcapped Meili Mountains, part of the Himalayas in China. The middle marvel is Comet Lemmon near its picturesque best early this month, showing not only a white dust tail trailing off to the right but its blue solar wind-distorted ion tail trailing off to the left. Far in the distance on the left is the magnificent central plane of our Milky Way Galaxy, featuring dark dust, red nebula, and including billions of Sun-like stars. Comet C/2025 A6 (Lemmon) is already fading as it heads back into the outer Solar System, while the Himalayan mountains will gradually erode over the next billion years. The Milky Way Galaxy, though, will live on — forming new mountains and comets — for many billions of years into the future.
