  Activities related to access to astronomical facilities and data could offer
an effective, entry-level path for outreach and astronomy education. The
Government of Italy proposed the Open Universe initiative that was adopted by
the United Nations Office of Outer Space Affairs. Education in astronomy is a
key method to promoting rational thinking and the scientific method. We shall
discuss how new methods using available data need to be used for outreach and
education to help vizualise and understand actual data. We shall show, using
GAIA DR2 data, how present data analysis and visualization tools can be used to
identify star clusters, moving groups and runaway stars. Thus, with this
example, real data can be used to understand stellar dynamics in the galaxy.
