The planetary nebula NGC 6302 is one the most-studied of cosmic entities of its kind, with a familiar shape and dazzling colors that live up to its “Butterfly Nebula” nickname.
This image takes the viewer on a deep dive into the heart of the Butterfly Nebula, NGC 6302.

The study’s authors were particularly surprised by the discovery of carbon-based molecules called polycyclic aromatic hydrocarbons (PAHs) in the Butterfly Nebula.
