阿爾尼塔克星、阿爾尼拉姆星和明塔卡星是這幅宇宙遠景中從東到西（從右上角到左下角）沿對角線排列的明亮藍星。這三顆藍色超巨星又被稱為獵戶座腰帶，它們的溫度和質量都比太陽高得多。它們位於 700 到 2000 光年之外，誕生於獵戶座的星際雲中。事實上，漂浮在這一區域的氣體和塵埃雲有一些令人驚訝的熟悉形狀，包括右上角阿爾尼塔克附近的黑暗馬頭星雲和火焰星雲。著名的獵戶座星雲本身就位於這個多彩星域的右側邊緣。望遠鏡框架在天空中的跨度將近 4 度。
原文：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.
