JWST sheds light on the structure of interstellar water ice

Using the James Webb Space Telescope (JWST), a team of researchers including Paola Caselli, Barbara Michela Giuliano and Basile Husquinet from MPE, have probed deep into dense cloud cores, revealing details of interstellar ice that were previously unobservable. The study, published in the journal Nature Astronomy, focuses on the Chamaeleon I region, using JWST's NIRCam to measure spectroscopic lines toward hundreds of stars behind the cloud.
