The phenomenon occurs anytime a flow exits a nozzle at supersonic speeds and at a pressure that is different than that of the external atmosphere. http://www.aerospaceweb.org/question/propulsion/q0224.shtml The pattern of evenly spaced rings sometimes visible in the exhaust of an engine is typically referred to as shock diamonds or Mach disks.

I've seen it before on other rocket enjines, and I've never figured out why it does that. Either way, that looks WAY COOL! --TwoDragons I wonder what physics are behind that neat "oscillating flame" look...?
