Colorful Clouds of Orion
Explanation: Revisiting one of the most famous nebulae in planet Earth's night sky, astrophotographer Robert Gendler has constructed this stunning, color-enhanced mosaic of the region surrounding the Great Nebula in Orion . As seen here, the clouds of Orion are dominated by the reddish emission nebula M42 near the bottom of the image, with blue reflection nebulae, including NGC 1977 , near the top. Strewn with dust lanes and dark nebulae, the striking cosmic apparitions surrounding Orion's stellar nurseries are about 1,500 light-years away and are themselves several light-years across. Located at the edge of a giant molecular cloud complex spanning hundreds of light-years, these nebulae represent only a small, but very visible(!), fraction of this region's wealth of interstellar material . Within these colorful clouds of Orion , astronomers have also identified what appear to be numerous infant solar systems .
