like HH 7611, which are described as "bright patches of nebulosity near newborn stars," will not be around as long as most objects in the universe.
The bursts of gas have shaped the turbulent surroundings into sneeze-like structures known as Herbig-Haro objects
. Launched due to magnetic fields around the forming star, these energetic releases can contain as much mass as our home planet, and cannon into nearby clouds of gas at hundreds of kilometres/miles per second.

, and measurements of a circumstellar disk," The Astrophysical Journal, vol.
The presence of young embryonic stars within the bluish reflection nebula NGC 7129 is betrayed by the tiny reddish Herbig-Haro objects
that dot the field.
Evidence for such stellar precursors comes from nebulae termed Herbig-Haro objects
, named after George Herbig and Guillermo Haro, who first studied them, albeit individually.
de Witt was registered for a PhD on shock-excited masers in Herbig-Haro objects
under the supervision of Smits and had a student assistantship post.
Astronomers have viewed with greater clarity than ever before a dust-cloaked region of starbirth in the Milky Way, The violent interactions they recorded there may shed new light on luminous knots of gas, known as Herbig-Haro objects
, whose origin has been controversial ever since they were discovered in the late 1940s.
are found to have short lives by astronomical standards; they are said to last just a few thousand years, and modify themselves dramatically over just a few years.
are nebulosities associated to high-velocity clouds of ionized gas.

Called Herbig-Haro objects
, these outflows--the birth cries of newborn stars--have been seen in many nebulae, though rarely as clearly as in Hubble's new Carina mosaic, which clearly shows bipolar jets erupting from two different elephant trunks.
are patches of material that are associated with baby stars, and that is where this protostar gets its name.
