在巨大的猎户座分子云复合体中，几个明亮的蓝色星云特别明显。照片中央是两个最突出的反射星云——被嵌入的明亮恒星的反射光照亮的尘埃云。更著名的星云是位于图像中心的M78，它是在200多年前编目的。它的左上角是鲜为人知的ngc2071。天文学家继续研究这些反射星云，以更好地了解内部恒星是如何形成的。整个红光来自于弥漫的氢气，它覆盖了猎户座的大部分复合体。在这个距离我们1500光年远的大星云附近，有猎户座星云、马头星云和巴纳德环带——图中左上角的白色带部分可见。几乎超空间：随机APOD生成器

In the vast Orion Molecular Cloud complex, several bright blue nebulas are particularly apparent. Pictured here in the center are two of the most prominent reflection nebulas - dust clouds lit by the reflecting light of bright embedded stars. The more famous nebula is M78, in the image center, cataloged over 200 years ago. To its upper left is the lesser known NGC 2071. Astronomers continue to study these reflection nebulas to better understand how interior stars form. The overall red glow is from diffuse hydrogen gas that covers much of the Orion complex that spans much of the constellation of Orion. Nearby in the greater complex, which lies about 1,500 light years away, are the Orion Nebula, the Horsehead Nebula, and Barnard's Loop -- partially seen here as the white band on the upper left.
