你能找到那颗彗星吗？彗星C/2025 R3 （PanSTARRS）穿过这张卫星轨迹网的某个地方，是一个穿过内太阳系的明亮访客。由于长时间的相机曝光，在这种情况下，超过10分钟的曝光，轨道卫星本身只能以条纹的形式出现。相反，在肉眼看来，卫星是在夜空中缓慢移动的点，通过反射阳光而发光——主要是在日落之后和日出之前。这张特色照片是两周前日出前在德国巴伐利亚州拍摄的。目前，由于另一个原因，很难看到彗星R3 PanSTARRS——因为它（从角度上）离太阳很近。当这颗彗星围绕太阳运行时，未来几周在南半球的天空可以看到它的最佳景象，尽管那时它将向星际空间飞去并逐渐消失。如果你还没有找到彗星，不要绝望；请仔细观察图像中心上方。

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.
