在遙遠的宇宙中，有三顆閃亮的藍色超大星星，分別叫做Alnitak、Alnilam和Mintaka。它們像串珠一樣排列在一起，稱為獵戶座的腰帶，從東到西（上右到下左）在星空中閃耀。這些星星比太陽更熱、更大，距離我們有700到2000光年遠，它們是在獵戶座的星際雲中出生的。在這片區域裡，還有一些挺熟悉的形狀，比如黑暗的馬頭星雲和接近Alnitak的烈焰星雲。著名的獵戶星雲就在這五顆亮星的右邊，而且它們在星空中覆蓋了將近4個度的範圍，讓人忍不住想要探索這奇妙的星空！
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.
