猎户座的大星云有隐藏的恒星。在可见光下，它看起来像猎户座中的一小块模糊的斑块。但这张照片是由韦伯太空望远镜拍摄的，它是红色和近红外光的代表性合成色。它以令人印象深刻的细节证实了猎户座星云是一个由年轻恒星、热气体和暗尘埃组成的繁忙社区。翻转图像显示了相同的图像在近红外进一步的代表性颜色。猎户座星云（M42）背后的力量是四边形——星云中心附近的一群明亮的恒星。围绕在明亮恒星周围的漫射和丝状光主要是被加热的星际尘埃。对这些图像的详细检查显示了意想不到的大量木星质量的双星（JuMBOs），这对木星质量的物体可能会给恒星形成的方式提供线索。整个猎户座星云，包括马头星云，将在接下来的几百万年里慢慢消散。APOD编辑发言：10月12日星期四下午6点在密歇根州霍顿

The Great Nebula in Orion has hidden stars. To the unaided eye in visible light, it appears as a small fuzzy patch in the constellation of Orion. But this image was taken by the Webb Space Telescope in a representative-color composite of red and very near infrared light. It confirms with impressive detail that the Orion Nebula is a busy neighborhood of young stars, hot gas, and dark dust. The rollover image shows the same image in representative colors further into the near infrared. The power behind much of the Orion Nebula (M42) is the Trapezium - a cluster of bright stars near the nebula's center. The diffuse and filamentary glow surrounding the bright stars is mostly heated interstellar dust. Detailed inspection of these images shows an unexpectedly large number of Jupiter-Mass Binary Objects (JuMBOs), pairs of Jupiter-mass objects which might give a clue to how stars are forming. The whole Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next few million years.
