NGC 206 和仙女座星雲
NGC 206 and the Star Clouds of Andromeda

這個被命名為 NGC 206 的大型恆星群與鄰近的仙女座星系的粉紅色恆星形成區一起,依偎在仙女座星系的塵埃臂中。這個螺旋星系也被稱為 M 31 ,距離我們只有 250 萬光年。NGC 206 位於這張仙女座星系盤西南部清晰細緻的特寫照片的中心。NGC 206 明亮的藍色恆星表明它還很年輕。事實上,它最年輕的大質量恆星還不到 1000 萬年。NGC 206 比銀河系盤面上由年輕恆星組成的疏散星團或銀河星團要大得多,橫跨約 4000 光年。其大小與附近旋渦 M 33 中的巨型恆星苗圃 NGC 604 和大麥哲倫星雲中的塔蘭圖拉星雲相當。
原文:The large stellar association cataloged as NGC 206 is nestled within the dusty arms of the neighboring Andromeda galaxy along with the galaxy's pinkish star-forming regions. Also known as M31, the spiral galaxy is a mere 2.5 million light-years away. NGC 206 is found at the center of this sharp and detailed close-up of the southwestern extent of Andromeda's disk. The bright, blue stars of NGC 206 indicate its youth. In fact, its youngest massive stars are less than 10 million years old. Much larger than the open or galactic clusters of young stars in the disk of our Milky Way galaxy, NGC 206 spans about 4,000 light-years. That's comparable in size to the giant stellar nurseries NGC 604 in nearby spiral M33 and the Tarantula Nebula in the Large Magellanic Cloud.
