[漢羅] M27：啞鐘星雲

咱 ê 太陽 紲落來會變做啥物？ 咱太陽 ê 未來，頭一个暗示 tī 1764 年 to̍h 有人無意中揣著矣。 彼陣，Charles Messier 當咧編一个星表。 內底是一寡 boăi kah 彗星相濫 ê 擴散天體。 Messier 星表 內底第 27 个天體，叫做 M27 抑是啞鐘星雲。 伊是一个 行星形星雲，是天頂上光 ê 行星形星雲 之一。 用雙筒望遠鏡 ùi 狐狸 ê 星座（狐狸座） ê 方向 to̍h 看會著。 光線 ùi M27 到咱愛開 1000 年 ê 時間。 相片 內底 ê 色光是 ùi 水素 kah 酸素 來 ê。 咱知影講，差不多閣 60 億年，咱 ê 太陽 to̍h 會 kā 伊 ê 氣體殼㧒出去，變做一粒行星形星雲，to̍h kah M27 仝款。 中央賰 ê 部份，to̍h 會變做一粒會發出 X-光、燒燙燙 ê 白矮星。 毋閣 tī 18 世紀 ê 科學，猶無法度了解 M27 ê 物理 kah 重要性。 To̍h 算是到今，行星形星雲 猶是 留足濟謎團 落來，包括 in 複雜 ê 形體 是 按怎 產生 ê。

[English] M27: The Dumbbell Nebula

What will become of our Sun? 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 toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27, featured here in colors emitted by hydrogen and oxygen. 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.
