在宇宙中漂流时，一团壮丽的星际尘埃云被恒星风和辐射雕刻成一个可识别的形状。它被恰当地命名为马头星云，位于巨大而复杂的猎户座星云（M42）中。这是一个潜在的有价值的物体，但很难用小型望远镜亲自观察，这张特色华丽的细节图像是由哈勃太空望远镜在轨道上拍摄的。这片黑暗的分子云距离我们大约1500光年，编号为巴纳德33，之所以能在上面看到它，主要是因为它被附近的大质量恒星猎户座西格玛的背光所照亮。在接下来的几百万年里，马头星云将慢慢改变它的外观形状，最终被高能星光摧毁。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

While drifting through the cosmos, a magnificent interstellar dust cloud became sculpted by stellar winds and radiation to assume a recognizable shape. Fittingly named the Horsehead Nebula, it is embedded in the vast and complex Orion Nebula (M42). A potentially rewarding but difficult object to view personally with a small telescope, the featured gorgeously detailed image was taken in infrared light by the orbiting Hubble Space Telescope. The dark molecular cloud, roughly 1,500 light years distant, is cataloged as Barnard 33 and is seen above primarily because it is backlit by the nearby massive star Sigma Orionis. The Horsehead Nebula will slowly shift its apparent shape over the next few million years and will eventually be destroyed by high energy starlight.
