在遙遠的星空中，有一些閃亮的星星和流星飛過，小朋友們，上天的朋友們可不是在Race哦！我們有兩顆特別的彗星，C/2025 K1 ATLAS（在左邊）和C/2025 R2 SWAN（在右邊）。它們最近在法國的留尼旺島附近碰巧出現在一起，形成了一幅美麗的圖片。雖然這顆比較暗的ATLAS彗星正朝著太陽跑來，可是它要在十月初才會最靠近太陽，屆時可能會是它最亮的時候，雖然我們還是需要透過相機慢慢觀察喔！而更亮的SWAN彗星現在卻是正在遠離太陽，不過它在十月中旬時要靠近地球，那時候，有些人可能可以用肉眼看到它呢！每顆彗星都有一種綠色的氣體雲，還有一條指向太陽的光尾巴。當然，這一切都很神奇，讓我們一起來期待這些宇宙的朋友帶來的奇妙吧！

It may look like these comets are racing, but they are not. Comets C/2025 K1 ATLAS (left) and C/2025 R2 SWAN (right) appeared near each other by chance last week in the featured image taken from France’s Reunion Island in the southern Indian Ocean. Fainter Comet ATLAS is approaching our Sun and will reach its closest approach in early October when it is also expected to be its brightest — although still only likely visible with long exposures on a camera. The brighter comet, nicknamed SWAN25B, is now headed away from our Sun, although its closest approach to Earth is expected in mid-October, when optimistic estimates have it becoming bright enough to see with the unaided eye. Each comet has a greenish coma of expelled gas and an ion tail pointing away from the Sun. Growing Gallery: Comet SWAN25B
