Herbig-Haro object
The Canton of Sains-en-Gohelle is one of the 15 cantons of the arrondissement of Lens, in the Pas-de-Calais département, in northern France.
Herbig-Haro Object
A small clump of emission nebulosity formed where jets of matter streaming from newly formed stars smash into the nearby interstellar gas.
HERBIG-HARO OBJECT - Small bright nebula in a star-forming region, named after the American astronomer George Herbig and Guillermo Haro who discovered the first three such objects in 1946-1947 in images of the nebula NGC 1999 in Orion.
Herbig-Haro Object
An object with many of the characteristics of a T Tauri star (e.g., its spectrum shows a weak continuum with strong emission lines), believed to be a star in the very early stages of evolution.
HERBIG-HARO OBJECTS Small, molecular clouds often occurring in pairs. They are thought to be where jets from young stars or protostars are colliding with the surrounding interstellar material.

Herbig-Haro objects Clouds of dust and gas that are either part of high-speed jets of gas streaming away from very young stars, or clouds of gas that have been hit by such jets.
Herbig-Haro object 30 (HH 30)
This newborn star is about half a million years old.
The star itself is obscured by its protoplanetary disk,
which is viewed edge-on at the bottom of the image as

Herbig-Haro objects are formed when highly energized particles--usually electrons and protons--are ejected from a young star and collide with nearby clouds of interstellar dust and gas.

A Herbig-Haro Object is formed when young stars eject jets of material into interstellar space.
Herbig-Haro objects (NASA Thesaurus) Celestial objects having many of the characteristics of a T Tauri star (e.g., their spectra show a weak continuum with strong emission lines), believed to be stars in the very early stages of development.
Examples of these Herbig-Haro objects (HH; named after George Herbig and Guillermo Haro who independently discovered this type of object) are shown in the images below.
HH 32, about 1,000 light-years from Earth, is an excellent example of a "Herbig-Haro object," which is formed when young stars eject jets of material back into interstellar space.

They are classified as planetary nebulae, supernova remnants, and diffuse nebulae, including reflecting, emission, and dark nebulae. Small, very bright nebulae called Herbig-Haro objects are found in dense interstellar clouds and are probably the ...
