Quizplus · Accepted Answer

A collection of 10⁵ to 10⁶ old stars in a region 30 to 100 light-years in diameter is called a globular cluster. Herbig-Haro objects are nebulae associated with newly formed stars, open clusters have fewer stars and are typically younger, and there is no such thing as a "giant cluster" in astronomy.
