  • Using slitless spectroscopy, JWST/NIRCam has simultaneously mapped three ice species across a dense cloud along 44 lines of sight. This cospatial mapping enables the local cloud chemistry to be probed with a spatial resolution of hundreds of astronomical units, representing a step change in ice mapping.

  • Amino acid glycine is shown here to form in the laboratory at temperatures of <15 K without the need for energetic processing (such as ultraviolet irradiation or particle bombardment). The implication is that amino acids could potentially form at the very earliest stages of star formation and persist until planetary systems are established.

  • Using JWST, the molecules seen in planetary atmospheres can be traced back to their cold origins in ices formed in dense interstellar clouds, before the onset of star formation, revealing that chemical diversity and complexity is achieved early.

  • Cold ice-covered dust grains grow during their journey from the interstellar medium to protoplanetary disks. JWST observations show that this growth begins before the protostellar phase and provide quantitative insights into the grain growth process.
