New results form HST on fast, colimated outflows in dying stars - the primary mechanism for shaping planetary nebulaeIn this paper, we briefly describe the results from imaging surveys of young PNe and PPNe with HST, and then present new results from detailed kinematic studies of several prominent objects which support our hypothesis for shaping PNe.
