Figure 1. The Swan Nebula (M 17)

M 17, also known as the Swan Nebula or Omega Nebula, is a bright emission nebula located in the constellation Sagittarius. It is one of the most massive star-forming regions in our galaxy, glowing with the light of ionized hydrogen gas energized by young, massive stars. Its distinct swan-shaped structure makes it a favorite object for both visual observers and astrophotographers.
