We present ALMA and VLA observations of the molecular and ionized gas at 0.1-0.3 ^ { \prime \prime } resolution in the Class 0 protostellar system IRAS 16293-2422 . These data clarify the origins of the protostellar outflows from the deeply embedded sources in this complex region . Source A2 is confirmed to be at the origin of the well known large scale north-east–south-west flow . The most recent VLA observations reveal a new ejection from that protostar , demonstrating that it drives an episodic jet . The central compact part of the other known large scale flow in the system , oriented roughly east-west , is well delineated by the CO ( 6-5 ) emission imaged with ALMA and is confirmed to be driven from within component A . Finally , a one-sided blueshifted bubble-like outflow structure is detected here for the first time from source B to the north-west of the system . Its very short dynamical timescale ( \sim 200 yr ) , low velocity , and moderate collimation support the idea that source B is the youngest object in the system , and possibly one of the youngest protostars known .
