Explanation: 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.

说明: 在这张宇宙景观中，从东到西（从右上到左下）沿着对角线排列的三颗明亮的蓝色恒星分别是参宿一（Alnitak）、参宿二（Alnilam）和参宿三（Mintaka）。这三颗蓝色超巨星也被称为猎户座腰带，它们比太阳更热且质量更大。这些恒星距离地球约700到2,000光年，诞生于猎户座已被广为研究的星际云中。事实上，这片区域漂浮的气体和尘埃云形成了一些令人惊讶的熟悉形状，例如在右上方靠近参宿一的黑暗马头星云和火焰星云。著名的猎户座星云则位于这片色彩缤纷星场的右边缘。望远镜拍摄的画面在天空中横跨了将近4度的范围。
