Bipolar Outflow

(streams of matter from the poles of a protostar)

A Bipolar Outflow is essentially a pair of Jets from the poles of a Protostar, and can also occur in stars late in their evolution. They are observed by the effect of heat on surrounding cloud or Interstellar Medium (ISM) due to the Shock Waves generated by the jet.

This glow can be the brightest aspect of some stages of Star Formation (SF), thus is considered an important means of locating and observing protostars.
