Summary The traditional theory of globular clusters is that their stars all formed at roughly the same time so stars of the same mass should have the same properties. But a close look at the clusters' color magnitude diagrams reveals most have two, occasionally, three populations of stars likely formed hundreds of millions of years apart. Spectra of certain elements in the stars reinforce the presence of multiple stellar populations.
