  • The JWST, with the aid of gravitational lensing, confirms the extreme distance of an ultra-faint galaxy at a redshift of 9.79, showing it to have a luminosity typical of the sources responsible for cosmic reionization and highly compact and complex morphology.

  • The infrared view of JWST has opened up the early Universe to study. This Perspective summarizes the key developments in our understanding of the high-redshift Universe from the first 18 months of JWST observations.

  • JWST detections of Si, C and Fe absorption lines in a bright z = 9.31 galaxy with a two-component clump structure suggest that mergers contributed to the rapid build-up of mass and chemical enrichment soon after the Big Bang.

  • A selected group of intermediate-redshift galaxies appear similar to primeval galaxies. Analysing spectra of these nearer analogues for chemical abundances and ionization levels gives an improved understanding of galaxies that are too faint to study well.
