NGC5189

Why is this beautiful nebula so complicated ? When a star is dying, it blast away its outer layers, usually into a simple overall shape. Sometimes this shape is a sphere, sometimes a double lobe, and sometimes a ring or a helix. In this image, however, no such simple structure has emerged. To help find out why, Hubble Space Telescope recently observed NGC 5189 in Hydrogen, Oxygen and Sulfur emission lines. Previous findings indicated the existence of multiple periods of material outflow, including a recent one that created a bright but distorted bar-like feature running horizontally across image center. Results appear consistent with a hypothesis that the dying star is part of a binary star system with a precessing symmetry axis. Given this new data, though, research is sure to continue.
