COMMENTARY: The Swan Nebula (alternately Omega or Horseshoe Nebula) is located in the beautiful teapot Constellation Sagittarius, at an approximate distance of 5,000 light-years. It is an emission nebula embedded in an open cluster of stars. On a dark night, it can be seen as a small fuzzy patch of light with the naked-eye. The patch of glowing gases forming the Swan's body spans about 12 light-years. Some six to seven hundred suns are sprinkled across the nebula, although only about 35 can be easily detected.
