在这张宇宙远景图中，三颗明亮的蓝色恒星沿着对角线从东到西（从右上到左下）。这三颗蓝色超巨星也被称为猎户座带，它们比太阳更热，质量也大得多。它们位于700到2000光年之外，是由猎户座的星际云形成的。事实上，在这个区域漂浮的气体云和尘埃云有一些令人惊讶的熟悉形状，包括右上方靠近Alnitak的黑暗马头星云和火焰星云。著名的猎户座星云本身就在这片彩色星空的右边。望远镜架在天空上的跨度几乎是4度。

Alnitak, Alnilam, and Mintaka are the bright bluish stars from east to west (upper right to lower left) along the diagonal in this cosmic vista. Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie from 700 to 2,000 light-years away, born of Orion's well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have some surprisingly familiar shapes, including the dark Horsehead Nebula and Flame Nebula near Alnitak at the upper right. The famous Orion Nebula itself is off the right edge of this colorful starfield. The telescopic frame spans almost 4 degrees on the sky.
