[漢羅] M33：三角星系

這个較細 ê 北方星座 三角座 內底有這个壯麗 ê 正向捲螺仔星系 M33。 伊較有名 ê 名是 風吹星系 kah 三角星系。 M33 ê 直徑超過 5 萬光年長，是 本星系群 內底第三大 ê，排 tī 仙女座 (M31) kah 咱 ê 銀河系後壁。 M33 離咱銀河系 差不多 有 3 百萬光年遠，有人認為伊是仙女座星系 ê 衛星星系。 毋閣蹛 tī 這兩个星系 ê 天文學家，可能會互相看著對方 ê 大捲螺仔系統。 Ùi 地球來 kā 看，這張清楚 ê M33 影像 有櫳櫳 ê 捲螺仔手骨，面頂有藍色星團 kah 粉紅仔色 ê 恆星形成 區。 實際上，ùi 這个星系中心 4 點 ê 方向看--去，有一个上光 ê 恆星形成區，是 NGC 604。 M33 kah M31 仝款，內底 ê 變星已經量過足濟擺矣。 這會當幫贊咱了解這款離咱較近 ê 捲螺仔星系，嘛會當予咱 閣較確定 宇宙 ê 大細。

[English] M33: The Triangulum Galaxy

The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. [About][About] 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy and astronomers in these two galaxies would likely have spectacular views of each other's grand spiral star systems. As for the view from planet Earth, this sharp image shows off M33's blue star clusters and pinkish star forming regions along the galaxy's loosely wound spiral arms. In fact, the cavernous NGC 604 is the brightest star forming region, seen here at about the 4 o'clock position from the galaxy center. Like M31, M33's population of well-measured variable stars have helped make this nearby spiral a cosmic yardstick for establishing the distance scale of the Universe.
