哈勃望遠鏡拍攝的錐狀星雲
The Cone Nebula from Hubble

恆星正在被稱為錐狀星雲的巨大塵柱中形成。在恆星苗圃中，錐狀星雲、柱狀星雲和雄偉的流動形狀比比皆是，在這些地方，氣體和塵埃雲被來自新生恆星的高能風吹拂著。錐狀星雲就是一個著名的例子，它位於明亮的銀河系恆星形成區 NGC 2264 中。這個由地球軌道上的哈勃太空望遠鏡拍攝的特寫合成照片以前所未有的細節捕捉到了錐狀星雲。錐狀星雲位於約 2500 光年外的摩諾塞洛斯星系，長約 7 光年，而圖中圍繞錐狀星雲鈍頭的區域直徑僅為 2 . 5 光年。在我們銀河系中，這個距離是太陽到半人馬座阿爾法星系中最近恆星鄰居的一半多。哈勃的紅外相機在 1997 年看到的大質量恆星NGC 2264 IRS 很可能就是雕刻錐狀星雲的風的來源，它位於影像的頂部。錐狀星雲的紅色面紗是由塵埃和發光的氫氣產生的。
原文：Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The Cone was captured in unprecedented detail in this close-up composite of several observations from the Earth-orbiting Hubble Space Telescope. While the Cone Nebula, about 2,500 light-years away in Monoceros, is around 7 light-years long, the region pictured here surrounding the cone's blunted head is a mere 2.5 light-years across. In our neck of the galaxy that distance is just over half way from our Sun to its nearest stellar neighbors in the Alpha Centauri star system. The massive star NGC 2264 IRS, seen by Hubble's infrared camera in 1997, is the likely source of the wind sculpting the Cone Nebula and lies off the top of the image. The Cone Nebula's reddish veil is produced by dust and glowing hydrogen gas.
