漆黑的馬頭星雲和發光的獵戶座星雲是截然不同的宇宙景觀。它們漂浮在 1500 光年之外的夜空中,是最容易辨認的星座之一,出現在上述令人驚歎的馬賽克照片的兩角。我們熟悉的馬頭星雲以烏雲的形式出現,在左下方長長的氫光(這裡顯示為金色)的映襯下,形成了一個小小的輪廓。阿爾尼塔克星是獵戶座腰帶中最東邊的一顆恆星,是馬頭星雲左下方最亮的一顆恆星。阿爾尼塔克的左側是火焰星雲,有明亮的發射雲和壯觀的暗塵埃道。獵戶座星雲(又名 M 42 )位於右上方,是一個壯觀的發射區。緊挨著它左側的是一個突出的反射星雲,有時也被稱為 "奔跑的人"。在整個區域內,可以很容易地追蹤到無處不在的發光氫氣卷鬚。 天體物理學家瀏覽天體物理學原始碼庫中的 3 , 500 多個程式碼
原文:The dark Horsehead Nebula and the glowing Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of the night sky's most recognizable constellations, they appear in opposite corners of the above stunning mosaic. The familiar Horsehead nebula appears as a dark cloud, a small silhouette notched against the long glow of hydrogen -- here shown in gold -- at the lower left. Alnitak is the easternmost star in Orion's belt and is seen as the brightest star just below and to the left of the Horsehead. To the left of Alnitak is the Flame Nebula, with clouds of bright emission and dramatic dark dust lanes. The magnificent emission region, the Orion Nebula (aka M42), lies at the upper right. Immediately to its left is a prominent reflection nebula sometimes called the Running Man. Pervasive tendrils of glowing hydrogen gas are easily traced throughout the region.
