在恒星风和辐射的雕琢下，一个宏伟的星际尘埃云偶然地呈现出了这个可识别的形状。它被称为马头星云，距离我们约1500光年，镶嵌在巨大的猎户座星云复合体中。这片大约5光年“高”的黑云被编目为巴纳德33，仅仅因为它的模糊尘埃在发光的红色发射星云IC 434的映照下才可见。恒星正在黑云中形成。形成鲜明对比的蓝色反射星云NGC 2023，环绕着一颗炙热的年轻恒星，位于完整图像的左下方。这张特色的彩色图像结合了窄带和宽带图像，这些图像是用几种不同的望远镜拍摄的。更新：在电报上关注APOD

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 of the full image. The featured gorgeous color image combines both narrowband and broadband images recorded using several different telescopes. New: Follow APOD on Telegram
