What is a globular cluster? EarthSky

WebA globular cluster is a dense aggregate of stars, spherical and symmetrical in shape. They are almost as old as the universe itself. Globular clusters are ancient, spherical collections of some of the oldest stars in the cosmos. The clusters are giant – they contain millions of stars densely packed together symmetrically.

The galaxy spans out around … WebGlobular Clusters are a dense collection of roughly a million stars. Since all of the stars in a globular cluster formed at roughly the same time, they can serve as cosmic clocks. This way of estimating the age of the universe is based on our understanding of the life cycles of stars. The life of a star depends upon its mass. WebExplanation: Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are perhaps 200 left. Many globular clusters were destroyed over the eons by repeated fateful encounters with each other or the Galactic center. blacklist taken off netflix
