在炽热的氢气中，恒星正在猎户座诞生。这些恒星托儿所位于巨大的猎户座分子云复合体的边缘，距离我们大约1500光年。这张详细的照片横跨著名的星座中心约12度，在右下方可以看到最近的大型恒星形成区——猎户座大星云。深马赛克还包括，靠近顶部中心，火焰星云和马头星云。用氢- α滤镜获得的图像数据为这张广角宇宙远景增添了其他显著特征：无处不在的充满能量的原子氢气卷须和巴纳德环线周围的部分区域。虽然猎户座星云和猎户座中的许多恒星很容易用肉眼看到，但从广泛的星际气体中发射出来的气体是微弱的，很难记录下来，即使是用望远镜观察这个星云丰富的复体也是如此。《天空惊喜》：《APOD》在你生日那天给你拍了什么照片？(1995年以后)

Cradled in red-glowing hydrogen gas, stars are being born in Orion. These stellar nurseries lie at the edge of the giant Orion molecular cloud complex, some 1,500 light-years away. This detailed view spans about 12 degrees across the center of the well-known constellation, with the Great Orion Nebula, the closest large star-forming region, visible toward the lower right. The deep mosaic also includes, near the top center, the Flame Nebula and the Horsehead Nebula. Image data acquired with a hydrogen-alpha filter adds other remarkable features to this wide-angle cosmic vista: pervasive tendrils of energized atomic hydrogen gas and portions of the surrounding Barnard's Loop. While the Orion Nebula and many stars in Orion are easy to see with the unaided eye, emission from the extensive interstellar gas is faint and much harder to record, even in telescopic views of the nebula-rich complex.
