Which was the role played by Astronomy and astronomers in former centuries? Extended review over the centuries to understand where we have reached, what was lost in that role, what is still needed, to be ready to face the attitude and new actions we should be able to take today.

Astronomy can still be used as a corner stone in our more modern world as a common ground to join people together: we are different individuals belonging to the very same Universe.

We can learn from the musicians of the West-Eastern Divan Orchestra to start concrete actions to undertake small steps towards a better dialogue among people with different backgrounds. And then we think:

• How can astronomers play a very useful role in the society by offering/transmitting knowledge over the place where we all belong: the Universe? To take deep conscious of this fact, and to have a basic but fundamental comprehension of it, can help the members of different societies of the world to discuss in good harmony with the aim of at least reaching the understanding of different possible positions.
• This could become a very useful connection between the work of astronomers and the world and show the relevance of Astronomy.

We have discussed how the communication of our knowledge on Astronomy can be useful for the society so that we can implement the possibility of a dialogue among different background people with the starting point of a shared Universe and a shared common interest to know more about this Universe.

The tool we want to use is then the popularization of our knowledge. This has to be achieved in a difficult equilibrium where simplifying should not imply loosing exactitude or correctness. We have to be extremely careful of the way in which we express ourselves. Besides, we should try to use all the existing multimedia communication tools in order to reach as many people as possible. And in that direction we wonder which role can the media play to help us to establish this initiative?

There are diverse very creative ways of making outreach. Professionals working in different institutions tell us about different methodologies that are used in relation with outreach and education. How can we adapt these activities to make outreach with the background purpose of using astronomy as a common ground?

Planning concrete steps to bring this possible role of astronomers to be a fact. Activities can be organized in working groups among VOSS Alumni and other astronomy associations to be spread afterwards.
