Why are star clusters almost ideal "laboratories" for stellar studies?

Question

Quizplus · Accepted Answer

Star clusters have the advantage of containing stars that are roughly the same age, have similar compositions, and are at the same distance from Earth. This makes it easier to analyze and compare their properties, such as luminosity, temperature, and chemical composition, and understand the processes that govern their evolution. In addition, star clusters can be used as benchmarks for determining distances and ages of other galaxies since their stars are well constrained in terms of their properties. Star clusters are almost ideal "laboratories" for stellar studies because stars in clusters have the same age, similar composition, and are at the same distance away. This allows for astronomers to compare the properties of various stars within the cluster and to make more accurate observations and predictions about their behavior.
