| Description: Structure of the H-R Diagram (b) The black bands indicate where data from various star clusters fall on the H-R diagram. The ages of turnoff points (in years) are listed in red alongside the main sequence. The age of a cluster can be estimated from the location of the turnoff point, where the cluster’s most massive stars are just now leaving the main sequence.
