The Group ASTRONOMIE & ASTROPHYSIQUE is one of the Contact Groups of the Fonds National de la Recherche Scientifique (FNRS).
This Contact Group is open to any research in astronomy and astrophysics.
The goal of the Group is to give the opportunity to astronomers and astrophysicists, especially the young researchers, to get better acquainted with the astronomical activities carried on in the various institutes of the country.
Since 2009, the Contact Group meeting is held together with the Astronomy Day of the Royal Observatory of Belgium.
