说明: 猎户座大星云是一个很有趣的天体。肉眼即可见的猎户座大星云，外观像是猎户座里的一片模糊小光斑。这张合成自广域红外线巡天卫星(WISE)四个红外光波段数据的影像，证实猎户座星云是一个熙攘喧嚣的区域，蜂拥着最近形成的恒星、炙热气体及黝黑尘埃。而驱动猎户座星云(M42)发光的主要能源，则是位在这幅主题影像中心附近的四边形星团内之恒星。影像里环拱在亮星周围的橘色辉光，源自被此区域大量複杂丝缕状尘埃所反射的星光。包括 马头星云在内的猎户座分子云複合体，在接下来的10万年里将逐渐分道扬镳。

Explanation: The Great Nebula in Orion is an intriguing place. Visible to the unaided eye, it appears as a smallfuzzy patch in the constellation of Orion.Butthis image, an illusory-color four-panel mosaic taken in different bands of infrared light with the Earth orbiting WISE observatory, shows the Orion Nebula to be a bustling neighborhood of recently formed stars, hot gas, and dark dust. The power behind much of the Orion Nebula (M42) is the stars of the Trapezium star cluster, seennear the center of the featured image.The orange glow surrounding the bright stars pictured here is their own starlight reflected by intricate dust filaments that cover much of the region. The current Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years.
