The official NASA/ESA version of the Ring Nebula, as seen by #JWST.
The Ring is a planetary nebula. Planetary nebulas got their name because they look like fuzzy planets through small telescopes. They were believed to be simple, round objects with a single dying Sun-like star at their centers. However, modern observations like this show a variety of intricate and complex structures.
How does a spherical star create a non-spherical nebula?

1. The Ring Nebula appears as a distorted doughnut. The nebula’s comparatively clear inner cavity appears in shades of blue and green, with subtle hoirzonal bands of darker and lighter blue gas in the center. The detailed ring transitions through shades of orange in the inner regions and pink in the outer region. It appears to have a rough texture, made of thousands of tiny filamets along the edge of the ring. Outside of the the ring are very faint, concentric arcs of gas.
