黑暗的马头星云和发光的猎户座星云形成了鲜明的对比。它们漂浮在1500光年外的夜空中最容易辨认的星座之一，出现在上面令人惊叹的马赛克的对角上。我们熟悉的马头星云看起来就像一片黑云，在左下角金色的氢光衬托下，它的轮廓很小。它是猎户座腰带上最东边的一颗星，在马头星的左边是一颗明亮的星。在参宿二的下方是火焰星云，明亮的发射云和引人注目的黑暗尘埃带。壮观的发射区域，猎户座星云（又名M42），位于右上方。紧挨着它的左边是一个突出的反射星云，有时被称为“奔跑的人”。到处都是发光的氢气卷须，很容易在整个地区找到。天体物理学家：在天体物理学源代码库中浏览3500多个代码

The dark Horsehead Nebula and the glowing Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of the night sky's most recognizable constellations, they appear in opposite corners of the above stunning mosaic. The familiar Horsehead nebula appears as a dark cloud, a small silhouette notched against the long glow of hydrogen -- here shown in gold -- at the lower left. Alnitak is the easternmost star in Orion's belt and is seen as the bright star to the left of the Horsehead. Just below Alnitak is the Flame Nebula, with clouds of bright emission and dramatic dark dust lanes. The magnificent emission region, the Orion Nebula (aka M42), lies at the upper right. Immediately to its left is a prominent reflection nebula sometimes called the Running Man. Pervasive tendrils of glowing hydrogen gas are easily traced throughout the region.
