This webpage is dedicated to an observing program for the James Webb Space Telescope Early Release Science.

The James Webb Space telescope (NASA/ESA/CSA) will be launched in 2019. During the first months of operations, 500 hours of director’s time has been allocated to 13  “Early Release Science” programs. The goals of these programs will be 1) to provide first-look public data to a wide community as soon as possible after launch, 2) to test the instruments and observing modes, 3) to help prepare the community for the open time proposals.

Our program concerns observations of  photodissociation regions and is coordinated by an international “Core team” of 20 scientists and supported by “science collaborators“. The PI team is composed of Olivier Berné, Emilie Harbart, and Els. Peeters. More information on the scientific objective is given in the rationale
