Messier 17, NGC6618

Messier 17 (M17), also known as the Omega Nebula, Swan Nebula, or Horseshoe Nebula, is a bright emission nebula located in the constellation Sagittarius. It lies about 5,000–6,000 light-years from Earth in the Milky Way and is part of a large star-forming region. The nebula spans approximately 15 light-years across and is rich in hydrogen gas, which gives it its characteristic red-pink glow due to ionization from nearby young, massive stars. M17 is one of the brightest and most massive star-forming regions in the galaxy, making it a popular target for amateur and professional astronomers alike.
