choose A B C D QUESTION 5 When astronomers look at globular clusters they don't see any stars hotter/more luminous than our Sun. What does this mean for the age of the globular cluster? The globular cluster doesn't have enough gravity to capture any stars more massive than our sun yet. The globular cluster is younger than the typical lifetime of a star like our Sun. The globular cluster is older than the typical lifetime of a star like our...
