Scientific paper

The last few years witnessed a change of perspective in the context of galaxy formation and evolution. The major role played by bars in the history of these fundamental building blocks of our universe was finally realized. However, and despite the fact that one of the major concerns of any physical science is to measure timescales for natural phenomena, we have as yet no established way to estimate the ages of these important galactic components. In this contribution we outline the method we developed to estimate bar ages and briefly describe its first results.
