The image above is a three-color composite of the young object Herbig-Haro 34 (HH-34) in the protostar stage of evolution. This object has a remarkable, very complicated appearance that includes two opposite jets that ram into the surrounding interstellar matter. This structure is produced by a machine-gun-like blast of "bullets" of dense gas ejected from the star at high velocities (approaching 250 km/sec). This seems to indicate that the star experiences episodic "outbursts" when large chunks of material fall onto it from a surrounding disc. HH-34 is located at a distance of approx. 1,500 light-years, near the famous Orion Nebula, one of the most productive star birth regions. The enigmatic "waterfall" to the upper left is a spectacular feature that is still an unexplained mystery.
