An artist's conception of the possible geometry of the G192.16 protostellar system.  North is up. 
The G192 S1  protostar is shown surrounded by a 130-AU-diameter accretion disk with a wide-angle outflow emanating from the central disk region.  
The G192 S2 companion is located 80 AU north of the primary S1 protostar.  
Near the northern edge of the circumbinary torus, a lower mass protostar with a well-collimated jet is shown.  The actual location of this protostar and its associated disk is unknown because it has not been detected.  However, the collimated jet and H2O masers along the jet axis have been detected (10).  Thus, the artist's rendition shows the protostar located somewhere along the observed jet axis.  
This drawing illustrates the dramatic difference between a typical jet outflow from a low-luminosity protostar that will become a star like our Sun (top of the image) and the outflow and accretion system of the massive protostar G192 S1.  
A scaled size of our solar system showing the 80-AU-diameter orbit of Pluto is in the bottom left. [Illustration: B. Starosta, NRAO/AUI/ NSF]
