An international collaboration of astronomers has reported the observation of the largest sample of galaxy groups to date, using data collected by the James Webb Space Telescope (JWST). The observations were conducted in a region of the sky known as COSMOS Web, which is a well-studied area for extragalactic research. By employing advanced imaging and data analysis techniques, the team was able to identify and study galaxy groups located up to more than 12 billion light years away. This study represents a significant milestone in extragalactic astronomy, as it allows researchers to examine the properties, formation, and evolution of galaxies at a much earlier stage in the universe's history. The findings contribute to a better understanding of how galaxies assemble into groups and clusters, and how these large-scale structures have evolved over cosmic time. The data from JWST, with its high sensitivity and resolution, enables astronomers to detect faint and distant galaxies that were previously inaccessible, thereby expanding knowledge of the universe's structure and evolution.
