你能找到那顆彗星嗎？在這片衛星軌跡交織的網絡中，正有一位閃亮的客人——彗星 C/2025 R3 (PanSTARRS)，它正穿過內太陽系。由於這張圖片的長時間曝光（超過10分鐘），這些繞軌衛星在相片上只是呈現為條紋。與此相反，肉眼所見的衛星則像是逐漸在夜空中移動的點，只會在日落後和日出前閃耀，因為它們反射著陽光。這幅精彩的圖片是兩週前在德國巴伐利亞拍攝的。在目前的情況下，彗星 R3 PanSTARRS 也難以見到，還有另一個原因——因為它與太陽非常接近。彗星圍繞太陽運行後，將在接下來的幾周內在南半球的天空中最佳觀賞，雖然這時它也將開始前往星際空間，變得越來越暗。如果你還沒找到那顆彗星，別擔心；請仔細看看圖片中心上方的部分。

Can you find the comet? Somewhere through this web of satellite trails is Comet C/2025 R3 (PanSTARRS), a bright visitor passing through the inner Solar System. Now, the orbiting satellites themselves only appear as streaks because of the long camera exposure, over 10 minutes in this case. On the contrary, to the eye, satellites appear as points that drift slowly across the night sky and shine by reflecting sunlight — primarily just after sunset and before sunrise. The featured image was taken just before sunrise two weeks ago from Bavaria, Germany. Presently, Comet R3 PanSTARRS is hard to see for even another reason — because it is so (angularly) close to the Sun. As the comet rounds the Sun, it will be best seen in coming weeks from southern hemispheree skies, although then it will be heading out to interstellar space and fading. If you haven’t yet found the comet, don’t despair; please take a closer look just above the image center.
