Images of the young binary XZ Tauri taken with HST/WFPC2 in 1995 and 1998 reveal an outflow of emission nebulosity in the form of an elongated bubble extending from the system. In 1995 this bubble was center-brightened and 4.3'' long, but in 1998 it was limb-brightened and extended to 5.0''. The expansion rate indicates that this feature is only about 23 years old. The appearance of limb brightening suggests that we are observing the formation of the post-shock cooling zone of a Herbig- Haro bowshock.
