彗星R3 PanSTARRS往哪个方向走？不是朝着图像上方的那颗恒星，因为那是参宿七，它在遥远的背景中，与彗星无关。不是通过图像中间的星云，因为那是女巫头星云，它也在很远的地方——但离参宿七不远。因为在过去的一周里，彗星C/2025 R3 （PanSTARRS）已经进入了南方的天空，现在在地球的南半球日落后向西看得最清楚。从角度上看，彗星R3 PanSTARRS正慢慢地向右上方移动，夜复一夜，很快就会进入猎户座。从空间上看，这颗彗星现在正在离开我们的太阳系，但在大约一周的时间里，南方天空的照相机应该还能看到它。这张特色图片是上周在智利的塞罗帕拉纳尔附近拍摄的。成长画廊：2026年的彗星R3 PanSTARRS
查看原文解释
Which way is Comet R3 PanSTARRS going? Not towards the star at the top of the image, because that is Rigel, which, being far in the background, is unrelated to the comet. Not through the nebula in the image middle, because that is the Witch Head Nebula and it, too, is far in the distance -- but not far from Rigel. Not into northern skies because over the past week Comet C/2025 R3 (PanSTARRS) has moved into southern skies and is now best visible in Earth's Southern Hemisphere toward the west after sunset. Angularly, Comet R3 PanSTARRS is slowly moving toward the upper right, night by night, and will soon be in the constellation Orion. Spatially, the comet is now headed out of our Solar System but should remain visible to cameras in southern skies for about a week. The featured image was captured last week near Cerro Paranal in Chile. Growing Gallery: Comet R3 PanSTARRS in 2026
