Just drop small drops of ink into water and you will see the same rings of turbulence. Dolphins blow air bubbles under water with the same structure. They do this for fun. I blew a smoke ring in 1962 and it floated across a still room.
If you watch very carefully all 'rings' degenerate into smaller rings.
When a star dies it can also give off rings.
Google solitons as it may give you some insight.
