NGC 5189.

NGC 5189 known as the Spiral Planetary is a small bright unusual planetary nebula in Musca at about 3000 light years distance and spans 3 light years across. The unusual spiral structure is though to be caused by a binary star system causing these curves and spiral patterns. These stars are by far too small to be seen.
