While this does show a meteor breaking apart, the resulting, expanding ring is called a &#8220;persistent train&#8221; and is NOT a debris ring.  Rather, it is glowing gas &#8211; charged gas that has been heated by compression caused by the meteor and giving off electrons (similar to how a neon sign works).
