[漢羅] M33：三角座星系

這个美麗 ê 正向捲螺仔星系 M33 是停踮北方星座三角座 內底 較細 ê 星系。 伊閣有一个較有名 ê 名稱是風吹星系，若無叫伊 三角座星系 嘛是會使。 M33 ê 直徑超過 5 萬光年，是 本星系群 內底第三大–ê，比仙女座星系 (M31) kah 咱 ê 銀河 較細。 M33 kah 咱銀河 ê 距離 差不多 有 300 萬光年遠。 伊去 hŏng 認為是仙女座星系 ê 衛星星系。 蹛踮這兩个星系內底 ê 天文學家，可能會互相看著對方這个壯觀 ê 大捲螺仔星系。 Ùi 銀河內底看，這張清楚 ê 相片 是 kā 地面望遠鏡 kah 太空望遠鏡 ê 觀測資料 組合出來 ê 影像。 咱會當看著 M33 櫳櫳 ê 捲螺仔手骨內底，有藍色星團 kah 粉紅仔色 ê 恆星形成區。 實際上，佇星系中心一點鐘方向彼糊上光–ê，是恆星形成區 NGC 604。 M33 kah M31 仝款，咱已經有量著足濟變星矣。 這會當幫贊咱 kā 這个厝邊捲螺仔星系當做一个宇宙尺度，按呢咱才有法度 建立 距離尺度，予咱了解 咱 ê 宇宙到底有偌大。

[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 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 the Milky Way, this sharp image combines data from telescopes on and around planet Earth to show 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 1 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.
