A Herbig-Haro object is a small bright nebula in a star-forming region, created when fast-moving (about 150 km/s) jets of material from an infant star collide with the interstellar medium. Jets around low- and intermediate-mass young stellar objects (YSOs) contain a fossil record of the recent accretion and outflow activity of their parent star-forming systems. Call The Express!!
