Herbig-Haro objects are small, bright regions of gas and dust found in space, typically associated with young stars. They form when jets of gas ejected from these stars collide with surrounding material, creating shock waves that heat the gas and cause it to glow. These objects are named after astronomers George Herbig and Guido Haro, who studied them in the 1950s. Herbig-Haro objects can provide valuable insights into the processes of star formation and the early stages of stellar evolution, helping scientists understand how stars and planetary systems develop over time.
