Open versus globular

Open clusters are young, sparse, and in the galactic disk; they disperse within a few hundred million years. Globulars are dense, spherical, and nearly as old as the galaxy.

Why they matter

Every star in a cluster is the same age and distance, which makes clusters the calibration bench for almost everything known about stellar evolution.
