在遙遠的太空中，有兩顆來自前所未見的新朋友，他們叫做彗星C/2025 R2 (SWAN)和C/2025 K1 (ATLAS)。這兩顆彗星像小船一樣，在太陽系內部游來游去。C/2025 R2 (SWAN)有著長長的明亮尾巴，好像在天空中畫出了一道閃閃發光的彩虹。它的周圍有一圈綠色的光圈，這對小朋友們來說非常神奇！在SWAN的上方和左邊，還有一顆比較微弱的彗星C/2025 K1 (ATLAS)，它也來到太陽系中玩耍，它在閃爍的星星之間顯得有些害羞。就像在一場比賽中，這兩顆彗星似乎正在一同奔向太陽，C/2025 R2 (SWAN)已經經歷過它和太陽最近的時刻，但C/2025 K1 (ATLAS)還在路程中，期待在10月8日的時候也能到達那裡！地球上親愛的朋友們，每當夜晚來臨，伴隨著紅色的小行星火星，他們也會非常開心地一起漂浮在太空之中，真的好有趣哦！
原文:
A new visitor to the inner Solar System, comet C/2025 R2 (SWAN) sports a long ion tail extending diagonally across this almost 7 degree wide telescopic field of view recorded on September 21. A fainter fellow comet also making its inner Solar System debut, C/2025 K1 (ATLAS), can be spotted above and left of SWAN’s greenish coma, just visible against the background sea of stars in the constellation Virgo. Both new comets were only discovered in 2025 and are joined in this celestial frame by ruddy planet Mars (bottom), a more familiar wanderer in planet Earth’s night skies. The comets may appear to be in a race, nearly neck and neck in their voyage through the inner Solar System and around the Sun. But this comet SWAN has already reached its perihelion or closest approach to the Sun on September 12 and is now outbound along its orbit. This comet ATLAS is still inbound though, and will make its perihelion passage on October 8.
