Conclusion

Attached to galaxies are globular clusters that formed at the same time as the galaxies. Globular cluster orbits take them through the galactic plane stripping them of interstellar gas. New star formation ceased soon after the formation of the clusters. We understand how stars age and die - larger stars reach their end points first. Smaller stars live for much longer than the current age of the universe. Globular cluster stars have age distributions that are consistent with the assertion that the universe formed 13.7 billion years ago.
