Abstract
HERBIG—H ARO jets are shocked beams of gas escaping supersonically from new-born stars. Here I report the discovery of an exceptionally fine jet, HH111, emerging from a young star still embedded in the Orion molecular clouds. The jet system displays four bow-shock-like features, moving in pairs in opposite directions from a 25-L⊙ infrared source. With an extent of more than 0.8 parsec, HH111 is the largest bipolar Herbig—Haro flow known. It is argued that such jets are highly transient phenomena that are related to eruptive accretion events in the build-up of the central star.
