What is the oldest universe?

Which type of galaxy are the oldest and least bright?
elliptical galaxies
Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren’t nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born. The existing stars inside an elliptical galaxy tend to be older, giving off more red light than younger stars.
