  • 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.

  • 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.

  • Observations of the jellyfish galaxy JO206 reveal an ordered, large-scale magnetic field and extremely high polarization, which can be explained by the accretion of magnetized plasma from the intergalactic medium that condenses onto the external layers of the tail.

  • In order for quiescent galaxies to maintain their low-to-non-existent star formation, there must be a mechanism to remove or heat gas that would otherwise cool to form stars; now supermassive black hole winds that are sufficient to suppress star formation in such galaxies are reported.

  • The majority of ‘jellyfish’ galaxies, characterized by long ‘tentacles’ of gas, also have active nuclei, indicating that gas is being fed to the central supermassive black hole by ram pressure.
