description Spiral Planetary Nebula (NGC 5189) Overview
NGC 5189, often called the Spiral Planetary Nebula, is a complex planetary nebula located in the southern constellation of Musca, approximately 1,800 light-years from Earth. It is distinguished by its unusual S-shaped morphology, which is produced by a precessing bipolar outflow of gas from its dying central binary star system. Astronomers study this nebula to understand the dynamic late-stage evolution of intermediate-mass stars. It is primarily observed and imaged by southern hemisphere astronomers due to its declination.
