  Our study's concern is about how to enlarge the scope of the virtual museum
concept from the mediation activities as they are carried out in today's
digital planetariums to training activities dedicated to the public. We assume
that these educational and cultural tools must be regarded as real immersive
virtual environments and therefore can provide visitors with a new
technological framing directly connected with a scientific field in the making,
cosmography, in its production environment. One of our goals is to make
visitors construct their own knowledge based directly on ongoing research data.
