[漢羅] M27：啞鐘星雲

咱 ê 太陽未來敢會變做按呢？ 真有可能喔！ 想欲知影咱 太陽 ê 未來，頭一个線索是 1764 年發現--ê。 彼 ê 時陣，Charles Messier 當咧 kā 一寡 kah 彗星會相濫 ê 霧霧的天體，編做目錄。 第 27 粒 Messier 天體，咱 kā 叫做 M27 抑是 啞鐘星雲，是一个 行星形星雲。 伊是天頂上光 ê 行星形星雲 之一，咱會當用 雙筒千里鏡 tī 狐狸 ê 星座（狐狸座）內底揣著伊。 咱到 M27 ê 距離差不多有 1000 光年遠。 相片內底 ê 色光 是 ùi 硫磺（紅色）、水素（青色）、kah 酸素（藍色）發射出來--ê。 咱知影講 差不多閣 60 億年，咱 ê 太陽 就會 kā 伊 ê 外層氣體殼擲--出去，變做 行星形星雲，就親像 M27 仝款。 中央賰 ê 部份會變做溫度足懸 ê 白矮星，發出 X-光。 毋過欲了解 M27 ê 物理 kah 特性，是超過 18 世紀 會當理解 ê 科學範圍。 就算是這馬，行星形星雲 嘛猶是有 足濟神祕 ê 部份 咱毋知。 親像是這款 複雜 ê 外形 到底是 按怎 產生--ê？ 咱嘛足想欲知影。

[English] M27: The Dumbbell Nebula

Is this what will become of our Sun? Quite possibly. The first hint of our Sun's future was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, one of the brightest planetary nebulae on the sky and visible with binoculars toward the constellation of the Fox (Vulpecula). It takes light about 1000 years to reach us from M27, featured here in colors emitted by sulfur (red), hydrogen (green) and oxygen (blue). We now know that in about 6 billion years, our Sun will shed its outer gases into a planetary nebula like M27, while its remaining center will become an X-ray hot white dwarf star. Understanding the physics and significance of M27 was well beyond 18th century science, though. Even today, many things remain mysterious about planetary nebulas, including how their intricate shapes are created.
