The Omega Nebula (also Swan Nebula) is an H II region in the constellation Sagittarius between 5,000 and 6,000 light-years from Earth and 15 light-years in diameter. It is one of the brightest and most massive star-forming regions of our galaxy. The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars.
