It is suggested that during the star's development, cones were ejected at near-right angles. The cone theory has some support with the radial spokes that might run along the cone walls. It is also speculated that the cones from a different viewpoint would look akin to the rings around supernova 1987A. MWC 922 here might also go nova someday (if it's over 8 solar masses). Looks like the camera's peering into a train tunnel, or the hourglass on the underside of a widow spider's abdomen. (no people, it is NOT the most deadly spider)
