Distant galaxy protocluster harbors a remarkably evolved core, observations find

Using the James Webb Space Telescope (JWST), an international team of astronomers has performed deep and high spectral resolution imaging of a distant protocluster of galaxies, designated A2744-z7p9OD. Results of the new observations, published July 8 on the arXiv preprint server, shed more light on the properties of this protocluster, revealing that it hosts a remarkably evolved core.
