是什么造成了土钦山-阿特拉斯彗星尾巴上不寻常的黑色条纹？这颗明亮的彗星在10月中旬拍摄的一些照片不仅捕捉到了它令人印象深刻的长尾和纤细的反尾，而且还捕捉到了一个相当意想不到的特征：长尾上有一条黑色条纹。黑斑的原因目前尚不清楚，也是一些争论的话题。可能的原因包括黑色尘埃的羽流，明亮尾巴的不同部分不同寻常地重叠，以及昏迷的密集部分在较小尘埃颗粒上的阴影。在10月14日从美国德克萨斯州拍摄的特色照片中可以看到这条条纹。为了帮助未来的分析，如果你拍到了清晰显示这条黑色条纹的彗星的好照片，请把它发送到APOD。图钦山-阿特拉斯彗星现在已经明显褪色，正在返回外太阳系。图片集：2024年的冢山彗星

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
