[漢羅] NGC 1360：花眉仔卵星雲

這个美麗 ê 星雲 是 tī 1500 光年遠 ê 所在。 Tī 這个望遠鏡景色內底，伊 ê 形體 kah 色光，予人感覺伊看起來 敢若是花眉仔卵。 這个宇宙雲有 3 光年闊，就 tī 南方星座 天爐座 ê 邊界內底。 NGC 1360 是行星形星雲，是卵形--ê，毋過伊毋是恆星拄開始 ê 階段。 伊是一粒 較老 ê 恆星，是恆星演化到上尾一个足短 ê 階段。 實際上，咱會當 tī 這張圖 ê 中心看著一粒中心恆星，伊是一个雙星系統，應該是有 2 粒演化尾期 ê 白矮星 組成--ê。 In ê 紫外光輻射 足強--ê，這 tī 可見光看袂著。 輻射能 kā 包 tī 白矮星外口 幾若層氣體內 ê 原子 ê 電子 擲出去。 NGC 1360 顯目 ê 青藍色，是電子 kah 雙離子化酸素原子 複合 ê 時陣 產生 ê 強輻射光。

譯者踅踅唸：「花眉仔卵星雲」ê 英語原文是 Robin's Egg Nebula，中文是『知更鳥卵星雲』，主要是咧形容這个星雲 ê 色光 Tiffiny 藍，kah『知更鳥蛋』ê 色水仝款 。 毋過『知更鳥』毋是台灣本地 ê 鳥仔，kah「出外講台語」ê 阿廷老師討論了後，伊建議用台灣本地 ê 鳥仔「花眉仔」（華語『台灣畫眉』）來翻。

[English] NGC 1360: The Robin's Egg Nebula

This pretty nebula lies some 1,500 light-years away, its shape and color in this telescopic view reminiscent of a robin's egg. The cosmic cloud spans about 3 light-years, nestled securely within the boundaries of the southern constellation Fornax. Recognized as a planetary nebula, egg-shaped NGC 1360 doesn't represent a beginning though. Instead it corresponds to a brief and final phase in the evolution of an aging star. In fact, visible at the center of the nebula, the central star of NGC 1360 is known to be a binary star system likely consisting of two evolved white dwarf stars, less massive but much hotter than the Sun. Their intense and otherwise invisible ultraviolet radiation has stripped away electrons from the atoms in their mutually surrounding gaseous shroud. The predominant blue-green hue of NGC 1360 seen here is the strong emission produced as electrons recombine with doubly ionized oxygen atoms.
