The calibration of the cosmic distance scale significantly impacts the determination of the age of globular star clusters. Cepheid and RR Lyrae variable stars serve as primary distance indicators for these clusters, although their relevance to age assessments is limited. Understanding this calibration is crucial for accurate age estimations. For further insights, refer to the study by Krauss and Chaboyer (2003) available at Caltech.
