Comet R3 PanSTARRS Behind Satellite Trails

你能找到這顆彗星嗎？在這片衛星軌跡交織的網中，某處便是彗星C/ 2025 R 3 （PanSTARRS），這是一位正穿越內太陽系的明亮訪客。由於相機曝光時間較長（本次超過 10 分鐘），這些繞行衛星本身在照片中僅呈現為光帶。 相反，肉眼所見，衛星呈現為在夜空中緩慢漂移的光點，它們透過反射陽光而發光——主要出現在日落之後和日出之前。這張特色圖片拍攝於兩週前日出前，地點位於德國巴伐利亞。 目前，R 3 PanSTARRS 彗星還因另一個原因難以觀測——它與太陽的角距離非常近。隨著彗星繞日執行，未來幾周在南半球的天空中將能看到它最清晰，儘管那時它正駛向星際空間並逐漸變暗。如果你還沒找到這顆彗星，別灰心；請仔細觀察圖片中心正上方。
原文：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.
