NotesIt is not unusual for planetary nebulae like this to show more energetic regions - known as FLIERS - extending out from their central stars. In the case of the Saturn Nebula, these lobes are extraordinarily prominent, giving the nebula an appearance not unlike the planet Saturn with its rings viewed edge-on.
