月琴山-阿特拉斯彗星的異常尾巴
The Unusual Tails of Comet Tsuchinshan-Atlas

是什麼在 "月琴山-阿特拉斯 "彗星的尾部形成了一條不尋常的暗條紋? 10 月中旬對這顆明亮彗星拍攝的一些影像不僅捕捉到了它令人印象深刻的長尾和細長的反尾,還捕捉到了一個相當出人意料的特徵:長尾上有一條黑條紋。目前還不清楚出現暗條紋的原因,也存在一些爭議。 可能的原因包括:一縷暗色塵埃、亮尾的不同部分異常地疊加在一起,以及較小塵埃顆粒上彗星彗尾密集部分的陰影。在 10 月 14 日從美國德克薩斯州拍攝的特寫圖片中,條紋清晰可見。為了幫助今後的分析工作,如果您拍攝到了清晰顯示出這一暗色條紋的彗星影像,請將其傳送給 APOD。月琴山-ATLAS 彗星現在已經明顯變暗,正在返回外太陽系。 相簿: 2024 年的月琴山-ATLAS 彗星
原文:What created an unusual dark streak in Comet Tsuchinshan-Atlas's tail? Some images of the bright comet during mid-October not only caught its impressively long tail and its thin anti-tail, but a rather unexpected feature: a dark streak in the long tail. The reason for the dark streak is currently unclear and a topic of some debate. Possible reasons include a plume of dark dust, different parts of the bright tail being unusually superposed, and a shadow of a dense part of the coma on smaller dust particles. The streak is visible in the featured image taken on October 14 from Texas, USA. To help future analyses, if you have taken a good image of the comet that clearly shows this dark streak, please send it in to APOD. Comet Tsuchinshan–ATLAS has now faded considerably and is returning to the outer Solar System. Gallery: Comet Tsuchinshan-ATLAS in 2024
