In the last years, several organic molecules, some of which of prebiotic interest, have been observed in different astronomical environments. For instance, Acetonitrile CH3CN was detected in the molecular cloud Sag B2 and in the protostar MWC480; formamide (a building block for sugars and amino-acids) was detected in some outer galaxies and in the protostar SVS13-A (in this case together
From the large number of exoplanets discovered by missions such as Kepler and CoRoT, it is clear that the presence of planets is a common feature in stars of our Galaxy. In particular, it has been estimated that on average each low mass star has one planet. Planets formation is thus an ubiquitous phenomenon across the Milky Way. It is
