[漢羅] 足特別 ê 紫金山-ATLAS 彗星

紫金山-ATLAS 彗星 ê 尾溜 內底 無四常 ê 烏暗線 是按怎來--ê？ 10 月中有翕著 ê 這粒足光 ê 彗星 相片，毋但翕著 予人印象足深 ê 長彗尾 kah 細細條 ê 倒反彗尾，嘛有一寡人 翕著 長 彗尾 內底 足特別 ê 烏暗 線。 這个烏暗線是按怎來--ê？ 到今猶 tī 咧討論。 有可能是 烏暗 塗粉 雲煙、無仝區 ê 彗尾 相疊、抑是 較厚 ê 彗鬚 內底一寡細粒塗粉粒產生 ê 烏影。 10 月 14 tī 美國德州翕著 ê 這張 相片 嘛有翕著這條烏暗線。 為著欲幫贊科學家分析這个現象，你若是有翕著有清楚烏暗線 ê 彗星相片，請 送來 APOD。 紫金山-ATLAS 彗星 這馬已經轉去 外太陽系 矣，所以伊 tī 天頂會 愈來愈暗。

[English] The Unusual Tails of Comet Tsuchinshan-Atlas

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.
