M17, Omega Nebula is part of huge cloud of molecular gas in the constellation of Sagittarius in which star formation is still taking place. Cluster of some 35 hot, young stars is contained within the nebula. These stars excite hydrogen atoms in the cloud to shine. The nebula contains large amounts of dark obscuring material. That material is sculptured by the intense radiation of stars in the nebula creating interesting features. Omega nebula is 15 ly across and its distance is between 5000 and 6000 ly.
