[漢羅] Messier 81

Messier 81 是 tī 地球天頂上光 ê 一个大閣 媠 ê 星系,伊 kah 咱 ê 銀河欲平大。 伊閣叫做 NGC 3031,嘛叫做 Bode 星系,是 tī 18 世紀予人發現 ê。 這个 大捲螺仔星系,會當 tī 北爿 ê 星座,大熊座(大隻熊),揣著。 Tī 這个 清楚閣詳細 ê 望遠鏡 景色內底,看會著 M81 光閣黃 ê 核心, 藍色 ê 捲螺仔手骨,粉紅仔色 ê 恆星形成區,kah 大片 ê 宇宙塗粉帶。 有一寡塗粉帶迒過星系盤(tī 倒爿中央),kah 其他有明顯 捲螺仔 特色 ê 星系無仝。 這个 突出 ê 塗粉帶,可能是 M81 kah 無 tī 這張影像內底 ê 厝邊星系 M82 互相倚近,才產生這个 掰袂離 ê 結果。 Tī M81 ê 大捲螺仔下跤,有一个較暗 ê,無規則 ê 衛星矮星系, Holmberg 9 號。 檢查 M81 內底 ê 變星,會當予 咱知影伊 ê 距離。 伊離咱有 1180 萬光年遠,是銀河外口 ê 星系。

[English] Messier 81

One of the brightest galaxies in planet Earth’s sky is similar in size to our Milky Way Galaxy: big, beautiful Messier 81. Also known as NGC 3031 or Bode’s galaxy for its 18th century discoverer, this grand spiral can be found toward the northern constellation of Ursa Major, the Great Bear. The sharp, detailed telescopic view reveals M81’s bright yellow nucleus, blue spiral arms, pinkish starforming regions, and sweeping cosmic dust lanes. Some dust lanes actually run through the galactic disk (left of center), contrary to other prominent spiral features though. The errant dust lanes may be the lingering result of a close encounter between M81 and the nearby galaxy M82 lurking outside of this frame. M81’s faint, dwarf irregular satellite galaxy, Holmberg IX, can be seen just below the large spiral. Scrutiny of variable stars in M81 has yielded a well-determined distance) for an external galaxy – 11.8 million light-years.
