Millions of Stars in Omega Centauri

Pictured above is the largest ball of stars in our Galaxy.
About 10 million stars orbit the center of this globular cluster - named
Omega Centauri - as this giant globular cluster orbits the center of our
Galaxy. Recent evidence indicates that Omega Centauri is by far the
most massive of the about 160 globular clusters in the Milky Way.
The stars in globular clusters are generally older, redder and less
massive than our Sun. Studying globular clusters tells us about the
history of our Galaxy and the age of the universe.
