One of the brightest nebulae in the night sky is Messier 42, the Orion Nebula, located south of Orion’s belt. At its core is the young Trapezium Cluster of stars, the most massive of which illuminate the surrounding gas and dust with their intense ultraviolet radiation fields, while protostars continue to form today in the OMC-1 molecular cloud behind.
