An international collaboration led by Assistant Professor Takuya Hashimoto (University of Tsukuba, Japan) and Researcher Javier Álvarez-Márquez (Spanish Center for Astrobiology) has used the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA) to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. This profound observation has revealed this protocluster's dense 'metropolitan' core, indicating accelerated galaxy growth. Simulations suggest this region will merge into a singular, massive galaxy in the forthcoming tens of millions of years, offering insights into early galactic birth and evolution.
