The Giant Herbig–Haro Flow HH 212 and Associated Star Formation The bipolar jet HH 212, among the finest collimated jets known, has so far been detected only in near-infrared H_2 emission. Bipolar outflows are fundamental characteristics of young stars and have been detected at all evolutionary stages from Class 0 to Class III. These outflows are detected in molecular, atomic, and ionized transitions, representing physical conditions from shock-heated fast moving plasmas to slower and denser molecular gas entrained from the ambient medium. Outflows are important sources of feedback into the ambient medium in star forming regions and form part of the self-regulation of star formation. The most dramatic manifestations of the outflow phenomenon are the Herbig-Haro jets, highly collimated high-velocity bipolar flows that emit mainly in Balmer lines, forbidden lines of [SII], [OII], [FeII], and molecular transitions of H2.
