Discovery of the most distant dwarf galaxy detected so far
An international team, including the Ikerbasque research professor of the University of the Basque Country (UPV/EHU) and associate of Donostia International Physics Center (DIPC) Tom Broadhurst, used the high resolution of the James Webb Space Telescope (JWST) combined with a powerful gravitational lens to conclude that the galaxies that formed in the early universe were typically very small, indicating a hierarchical process of evolution from dwarf galaxies gradually merging together as a result of mutual gravity, until massive galaxies such as our Milky Way were formed. The study has just been published in the journal Science.
