猎户座著名的马头星云并不孤单。深度曝光显示，在照片中央右侧可见的熟悉的黑色凹痕，是一个巨大的吸收尘埃和发光气体的复合体的一部分。这张引人注目的照片详细描绘了一幅复杂的气体缕和充满尘埃的细丝织锦，这些细丝是由恒星风和古老的超新星在千万年中形成和雕刻的。火焰星云在马头星云的左边以橙色可见。为了突出尘埃和气体，大多数恒星都被数字删除了，尽管一个值得注意的例外是火焰星云上方的宿七星，它是猎户座著名的三颗恒星带中最右边的恒星。马头星云位于距猎户座1500光年远的地方。美国宇航局报道：阿尔忒弥斯1号登月任务教师和学生：在课堂上利用APOD的想法

The famous Horsehead Nebula in Orion is not alone. A deep exposure shows that the dark familiar shaped indentation, visible just right of center, is part of a vast complex of absorbing dust and glowing gas. The featured spectacular picture details an intricate tapestry of gaseous wisps and dust-laden filaments that were created and sculpted over eons by stellar winds and ancient supernovas. The Flame Nebula is visible in orange just to the Horsehead's left. To highlight the dust and gas, most of the stars have been digitally removed, although a notable exception is Alnitak, just above the Flame Nebula, which is the rightmost star in Orion's famous belt of three aligned stars. The Horsehead Nebula lies 1,500 light years distant towards the constellation of Orion. NASA Coverage: Artemis I Mission to the Moon Teachers & Students: Ideas for utilizing APOD in the classroom
