On the occasion of the World Year of Astronomy in 2009, this documentary offers to enter the wings of one of the biggest European Services of Astrophysics (the SAp) and to discover, behind research, those who are in charge of it.
For one year, we follow the everyday life of persons who live the countdown of the launch of the Herschel satellite, the biggest space telescope to date, or who go to the famous APEX telescope to over 5000 meters altitude in Chile, for observations.
