很少有宇宙景观能像猎户座星云那样激发人们的想象力。这个星云也被称为M42，它的发光气体围绕着1500光年外巨大的星际分子云边缘的炽热年轻恒星。猎户座星云提供了一个最好的机会来研究恒星是如何诞生的，部分原因是它是最近的大型恒星形成区域，但也因为星云的高能恒星已经吹走了遮挡我们视线的模糊气体和尘埃云——提供了一个近距离观察恒星诞生和进化的一系列阶段的机会。这张猎户座星云的特色图像是有史以来最清晰的图像之一，使用哈勃太空望远镜的数据构建而成。整个猎户座星云跨度约40光年，与太阳位于银河系的同一螺旋臂上。

Few cosmic vistas excite the imagination like the Orion Nebula. Also known as M42, the nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1,500 light-years away. The Orion Nebula offers one of the best opportunities to study how stars are born partly because it is the nearest large star-forming region, but also because the nebula's energetic stars have blown away obscuring gas and dust clouds that would otherwise block our view - providing an intimate look at a range of ongoing stages of starbirth and evolution. The featured image of the Orion Nebula is among the sharpest ever, constructed using data from the Hubble Space Telescope. The entire Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.
