Herbig–Haro object - Wikipedia, the free encyclopedia

Herbig–Haro object - Wikipedia, the free encyclopedia:

 "Herbig–Haro objects (HH) are small patches of nebulosity associated with newly born stars, and are formed when narrow jets of gas ejected by young stars collide with clouds of gas and dust nearby at speeds of several hundred kilometres per second. Herbig–Haro objects are ubiquitous in star-forming regions, and several are often seen around a single star, aligned with its rotational axis."
