The most detailed and complete images ever taken of a Photo-Dissociation Region (PDR) in the closest site of massive star formation, the Orion Molecular Cloud, have been obtained with the Keck telescope and portends what JWST should soon accomplish. These observations are critical for understanding the interaction of young massive stars with the gas and dust cloud in which they are born and where Sun-like stars form.
The PLATO project has reached a new decisive stage in the development of the calibration structure for the cameras intended for flight at IAS. The first EM (Engineering Model) camera to be calibrated by the three Test Houses of the PLATO consortium has just arrived at the IAS. This measurement campaign will allow the three production sites to be validated with the same functional camera, which is a prerequisite for being authorised to host all the flight cameras.
The first data were presented on Tuesday 12 July. They confirm the exceptional performance of the JWST and its four scientific instruments (NIRSPec, NIRISS, NIRCam, MIRI), in particular the angular resolution and sensitivity which are often better than predicted.
Adélie Gorce was awarded the Astronomy & Astrophysics Journal Best PhD Thesis Award on the 29th June 2022 during a ceremony at the European Astronomical Society's annual conference.
On the occasion of its thirtieth anniversary, the Institut d'Astrophysique Spatiale (IAS - CNRS, Université Paris-Saclay) wished to highlight its activities and the know-how of its staff, in the form of a film lasting just over an hour, directed by Frédéric Hullin, a video maker from the Université Paris-Saclay.
