很少有宇宙美景能像獵戶座大星雲一樣激發人的想象力。肉眼看到的是一個模糊而平淡的天體汙點,最近的大型恆星形成區遍佈這幅色彩鮮豔的望遠鏡影像。獵戶座星雲在梅西耶星表中被命名為M 42 ,熾熱的氣體和塵埃環繞著年輕的恆星。M 42 直徑約 40 光年,位於一個巨大的星際分子云的邊緣,距離太陽只有 1500 光年,與太陽位於銀河系的同一旋臂中。包括畫面左側的帶灰塵的藍色反射星雲NGC 1977 (也被稱為 "奔跑者 "星雲)在內,星雲只代表了我們銀河系附近豐富的恆星形成物質的一小部分。在這個研究得很透徹的恆星苗圃中,天文學家們還發現了似乎是無數個太陽系的雛形。
原文:Few cosmic vistas can excite the imagination like The Great Nebula in Orion. Visible as a faint, bland celestial smudge to the naked-eye, the nearest large star-forming region sprawls across this sharp colorful telescopic image. Designated M42 in the Messier Catalog, the Orion Nebula's glowing gas and dust surrounds hot, young stars. About 40 light-years across, M42 is at the edge of an immense interstellar molecular cloud only 1,500 light-years away that lies within the same spiral arm of our Milky Way galaxy as the Sun. Including dusty bluish reflection nebula NGC 1977, also known as the Running Man nebula at left in the frame, the natal nebulae represent only a small fraction of our galactic neighborhood's wealth of star-forming material. Within the well-studied stellar nursery, astronomers have also identified what appear to be numerous infant solar systems.
