原文:
Sculpted by stellar winds and radiation, a magnificent interstellar dust cloud by chance has assumed this recognizable shape. Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex. About five light-years “tall”, the dark cloud is cataloged as Barnard 33 and is visible only because its obscuring dust is silhouetted against the glowing red emission nebula IC 434. Stars are forming within the dark cloud. Contrasting blue reflection nebula NGC 2023, surrounding a hot, young star, is at the lower left. The gorgeous featured image combines both narrowband and broadband images.

由恆星風和輻射雕塑而成，這個壯麗的星際塵埃雲碰巧呈現出這個可識別的形狀。恰如其分地被命名為「馬頭星雲」（Horsehead Nebula），它距離地球約1,500光年，嵌入於廣大的獵戶座雲輪廓中。這個約五光年「高」的黑暗雲氣被列為巴納德33（Barnard 33），僅憑它的塵埃在發光的紅色發射星雲IC 434前形成的陰影而可見。這個黑暗的雲層內正在形成恆星。位於左下角的對比藍色反射星雲NGC 2023，圍繞著一顆炙熱、年輕的恆星。這張美麗的特寫照片結合了窄帶和寬帶圖像。
