NGC 1365 :壯麗的島嶼宇宙
NGC 1365: Majestic Island Universe

棒狀螺旋星系 NGC 1365 是一個真正雄偉的宇宙島,直徑約 20 萬光年。NGC 1365 位於僅 6000 萬光年遠的微弱但熾熱的福納克斯星座,是研究得很透徹的福納克斯星系團的主要成員。這張清晰的彩色圖片顯示了該星系中央條帶兩端附近以及旋臂上強烈的紅色恆星形成區。從精細的細節中可以看到,遮擋的塵埃通道穿過星系明亮的核心。在核心處有一個超大質量黑洞。天文學家認為,NGC 1365 的突出條帶在星系的演化過程中起著至關重要的作用,它將氣體和塵埃捲入恆星形成的漩渦,並最終將物質送入中央黑洞。
原文:Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the faint but heated constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This sharp color image shows the intense, reddish star forming regions near the ends of the galaxy's central bar and along its spiral arms. Seen in fine detail, obscuring dust lanes cut across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.
