麥克諾特彗星的壯麗尾巴
The Magnificent Tail of Comet McNaught

2007 年的大彗星麥克諾特彗星長出了一條壯觀的絲狀長尾。 這條壯觀的尾巴遍佈整個天空，南半球的觀測者可以在日落後看到好幾天。 令人驚歎的離子尾在長時間、廣角相機曝光時顯示出最大的範圍。 在某些時候，許多北半球的觀測者也能在地平線上方看到彗尾本身。據估計，C/ 2006 P 1 （麥克諾特）彗星的峰值亮度為- 5 （負五等），彗星的發現者在 2007 年 1 月日落後從澳大利亞的賽丁泉天文臺拍攝到了這張照片。麥克諾特彗星是幾十年來最亮的一顆彗星，隨著它進一步移向南部天空，遠離太陽和地球，它的亮度逐漸減弱。在接下來的一個月裡，作為 2024 年大彗星候選者之一的月琴山-ATLAS 彗星將展示出從地球上可見的最壯觀的彗尾。
原文：Comet McNaught, the Great Comet of 2007, grew a spectacularly long and filamentary tail. The magnificent tail spread across the sky and was visible for several days to Southern Hemisphere observers just after sunset. The amazing ion tail showed its greatest extent on long-duration, wide-angle camera exposures. During some times, just the tail itself was visible just above the horizon for many northern observers as well. Comet C/2006 P1 (McNaught), estimated to have attained a peak brightness of magnitude -5 (minus five), was caught by the comet's discoverer in the featured image just after sunset in January 2007 from Siding Spring Observatory in Australia. Comet McNaught, the brightest comet in decades, then faded as it moved further into southern skies and away from the Sun and Earth. Over the next month, Comet Tsuchinshan–ATLAS, a candidate for the Great Comet of 2024, should display its most spectacular tails visible from the Earth.
