James Webb Space Telescope and ALMA capture the core of the most distant galaxy protocluster

The study of how individual stars are born and die in galaxies, how new stars are born from remnants of old stars, and how galaxies themselves grow are important themes in astronomy, as they provide insight into our roots in the universe. Galaxy clusters, one of the largest structures in the universe, are the assembly of more than 100 galaxies which are bound together through mutual gravitational force.
