    JWST NIRCam observed the central part of the Orion Nebula, including proplyd 114-426. This observation found a dip at 3 μm, which is seen as evidence of water ice . The grain size was estimated to be smaller than 0.25 to 5 μm and the dust+ice mass of the disk was estimated to be 0.46 M E in the silhouette region. [ 3 ]

    The Orion Nebula is an archetypical example of star formation, from the massive, young stars that are shaping the nebula to the pillars of dense gas that may be the homes of budding stars. Key elements of star formation are only available by observing in wavelengths other than the optical.
