Star-forming region called Chamaeleon Cloud I (Cha I), reveals dusty-dark clouds where stars are forming, dazzling reflection nebulae glowing by the light of bright-blue young stars, and radiant knots called Herbig-Haro objects. Herbig-Haro objects are bright clumps and arcs of interstellar gas shocked and energized by jets expelled from infant “protostars†in the process of forming. The white-orange cloud at the bottom of the image hosts one of these protostars at its center. Its brilliant white jets of hot gas are ejected in narrow torrents from the protostar’s poles, creating the Herbig-Haro object HH 909A. This 315-million-pixel composite image is comprised of 23 observations made by Hubble’s Advanced Camera for Surveys. Gaps between those observations were filled by 20 Wide Field and Planetary Camera 2 images. Any remaining gaps were filled with ground-based data from ESO’s VISTA VIRCAM.
