[漢羅] M1：毛蟹星雲

毛蟹星雲 ê 編號是 M1，伊毋是彗星，是 18 世紀 Charles Messier 星表頭一个天體。 實際上，咱這馬已經知影 毛蟹星雲 其實是一个 超新星殘骸，是大質量恆星死亡爆炸了後 ê 雲屑仔。 天文學家 tī 1054 年 ê 時陣 to̍h 有發現伊 矣。 這是用 地面望遠鏡翕 ê 影像，是 kā 闊頻 kah 狹頻資料鬥做這張遮爾清楚 ê 彩色相片。 狹頻資料是追蹤硫磺離子、水素離子、酸素原子 ê 發射線，是欲探索 脹大星雲 內底交纏做伙 ê 雲絲。 對現代天文學家來講，其中上特別 ê 天體是 毛蟹星雲脈動星，to̍h 是相片中央上光彼粒，這是一粒一秒鐘踅 30 擺 ê 中子星。 這粒恆星核心崩塌 ê 殘骸 to̍h kah 宇宙發電機 仝款，伊是毛蟹星雲 ê 動力來源，予伊 tī 電磁波頻譜產生發射線。 毛蟹星雲差不多是 12 光年闊，伊 tī 金牛座 內底，離咱干焦 6500 光年遠爾爾。

[English] M1: The Crab Nebula

The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. This sharp, ground-based telescopic view combines broadband color data with narrowband data that tracks emission from ionized sulfur, hydrogen, and oxygen atoms to explore the tangled filaments within the still expanding cloud. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as a bright spot near the nebula's center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is a mere 6,500 light-years away in the constellation Taurus.
