  • Little is known about the star-birth activity of the earliest galaxies. Observations of a particularly distant galaxy provide evidence for such activity when the Universe was just 2% of its current age.

  • Synergies between JWST and ALMA are providing a multiwavelength view of galaxies, active galactic nuclei and the interstellar medium at high redshifts. This Review provides an overview of results so far and identifies areas for future development.

  • Gravitationally magnified images of a faint galaxy from only 500 million years after the Big Bang suggest that galaxies of that age may be the dominant source of the radiation responsible for the re-ionization of the intergalactic medium.

  • A search for galaxies at z≈7–8, roughly 700 million years from the Big Bang finds only one candidate galaxy at z≈7–8, where ten would be expected if there were no evolution in the galaxy population between z≈7 and z≈6. The simplest explanation is that the Universe is just too young to have built up many luminous galaxies at z≈7–8 by hierarchical merging of small galaxies.

  • A study of 36 massive galaxies at redshifts between 5 and 9 from the JWST FRESCO survey finds that galaxy formation of the most massive galaxies is 2–3 times higher than the most efficient galaxies at later epochs.

  • The neighbourhoods of extremely bright astronomical objects called quasars in the early Universe have been incompletely probed. Observations suggest that these regions harbour some of the most massive known galaxies. See Letter p.457

  • The emission of singly ionized carbon is used to identify two galaxies with redshifts of nearly 7—corresponding to the Universe’s first billion years—and with velocity structures suggestive of rotation.
