[漢羅] 烏暗 Lī-póng 星雲

天頂彼條奇怪 ê 咖啡色 lī-póng 是啥物？ 咱咧觀測 星團 NGC 4372 ê 時陣，觀測者定定注意著附近有一條烏暗帶，伊 ê 角寸尺差不多有 3 度 長。 實際上，這條是一个長 分子雲，叫做烏暗 Doodad 星雲，抑是 烏暗 Lī-póng 星雲。 （Doodad 是土話，是「物件」、「毋知彼是啥」ê 意思。） 相片內底 ê 烏暗 Lī-póng 星雲 就佔 tī 這个豐富多彩 ê 星場中心。 伊 ê 色較深，是因為 星際塗粉 較厚，kā 可見光 散射造成--ê。 上倒爿彼个 霧霧 ê 白點 是 球形星團 NGC 4372，伊正爿頂懸彼粒藍星是 胡蠅座 gamma。 咱只要用較好 ê 雙筒千里鏡 看 tùi 南方 ê 胡蠅座 就會當揣著 烏暗 Lī-póng 星雲。

[English] The Dark Doodad Nebula

What is that strange brown ribbon on the sky? When observing the star cluster NGC 4372, observers frequently take note of an unusual dark streak nearby running about three degrees in length. The streak, actually a long molecular cloud, has become known as the Dark Doodad Nebula. (Doodad is slang for a thingy or a whatchamacallit.) Pictured here, the Dark Doodad Nebula sweeps across the center of a rich and colorful starfield. Its dark color comes from a high concentration of interstellar dust that preferentially scatters visible light. The globular star cluster NGC 4372 is visible as the fuzzy white spot on the far left, while the bright blue star gamma Muscae is seen to the cluster's upper right. The Dark Doodad Nebula can be found with strong binoculars toward the southern constellation of the Fly (Musca).
