R 3 PanSTARRS 彗星正朝哪個方向移動？它並非朝向影像頂部的恆星，因為那是參宿七，它位於遙遠的背景中，與彗星毫無關聯。它也不會穿過影像中央的星雲，因為那是女巫頭星雲，它同樣位於遙遠的距離——但距離參宿七並不遠。 它也不會進入北半球夜空，因為過去一週裡，彗星C/ 2025 R 3 （PanSTARRS）已移入南半球夜空，目前在日落後面向西方的方向上，在地球南半球最為清晰可見。 從角位置來看，R 3 PanSTARRS 彗星正夜復一夜地緩慢向右上方移動，不久將進入獵戶座。從空間位置來看，這顆彗星目前正駛離我們的太陽系，但在未來約一週內，南半球的天文攝影愛好者仍能透過相機觀測到它。 本文配圖攝於上週，拍攝地點位於智利的帕拉納爾山附近。 相簿持續更新： 2026 年的R 3 PanSTARRS 彗星
原文：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
