恒星正在被称为锥状星云的巨大尘埃柱中形成。锥状、柱状和雄伟的流动形状在恒星托儿所中比比皆是,那里的气体和尘埃云被新生恒星的高能风雕刻而成。锥状星云,一个著名的例子,位于明亮的星系恒星形成区NGC 2264内。这张圆锥的特色图像是最近在智利的El Sauce天文台用半米望远镜拍摄的,经过24小时的曝光。圆锥星云位于2500光年外的独角兽星座(麒麟座),它的圆锥形柱延伸约7光年。大质量恒星NGC 2264 IRS,可能是形成锥状星云的风的来源,位于图像的顶部。锥状星云的红色面纱是由发光的氢气产生的。探索+拓展:APOD研究生研究职位开放

Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where clouds of gas and dust are sculpted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The featured image of the Cone was captured recently combining 24-hours of exposure with a half-meter telescope at the El Sauce Observatory in Chile. Located about 2,500 light-years away toward the constellation of the Unicorn (Monoceros), the Cone Nebula's conical pillar extends about 7 light-years. The massive star NGC 2264 IRS, 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 glowing hydrogen gas.
