Star clusters
935 CATALOGUEDStars born together and still travelling together — loose open groups, or ancient globes of hundreds of thousands.

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.
