R 3 PanSTARRS:一顆獵戶座彗星
R3 PanSTARRS: An Orion Comet

R 3 PanSTARRS 彗星或許最令人難忘的身份就是“獵戶座彗星”。主要原因在於,當C/ 2025 R 3 (PanSTARRS)彗星經過這標誌性的星座前方時,其彗尾的可見度正處於最壯觀的階段。 儘管較為罕見,但也有其他明亮的彗星曾穿越獵戶座,包括 2015 年的洛夫喬伊彗星、 1997 年的海爾-博普彗星以及 1264 年的大彗星。這張精選圖片拍攝於上週,攝於紐西蘭的克雷吉本山脈,透過長時間曝光效果最佳。 在深空背景中,可見獵戶座大星雲、巴納德環,以及透過R 3 彗星尾部若隱若現的明亮恆星賽弗(Saiph)——它是獵戶座中第六亮的恆星。隨著R 3 PanSTARRS 彗星繼續向南移動,其亮度正逐漸減弱,預計將在未來幾天內進入獨角獸座(Monoceros)。 天空驚喜:在你的生日那天,APOD(每日天文圖片)展示了哪張圖片?( 1995 年之後)
原文:Comet R3 PanSTARRS might be best remembered as an Orion comet. A key reason is because Comet C/2025 R3 (PanSTARRS) was near its most spectacular -- in terms of tail visibility -- when passing in front of the iconic constellation. Although rare, other bright comets, too, have ventured across Orion, including Lovejoy in 2015, Hale-Bopp in 1997, and the Great Comet of 1264. Best visible in long duration exposures, the featured image was captured last week from the Craigieburn Mountain Range in New Zealand. Visible in the deep background image are the Orion Nebula, Barnard's Loop, and through R3's tail, the bright star Saiph, the sixth brightest star in the constellation of Orion. Comet R3 PanSTARRS continues to fade as it moves further south, passing into the constellation of the Unicorn (Monoceros) in the next few days.
