Which of the following statements about globular clusters is true?

Question

Quizplus · Accepted Answer

Globular clusters are collections of stars that are tightly bound by gravity, often containing older stars. Most stars in these clusters are indeed older, which means they are typically at later stages in their evolution, manifesting as yellow or reddish in color. This is because the most massive and quickly evolving stars have already ended their life cycles, leaving behind the less massive, longer-lived stars that tend to be cooler and thus redder.
