Galaxies in the Loktak Protocluster were 1.4x larger in optical light than similar galaxies in sparse environments, despite comparable star-forming cores. This discovery proves environmental effects influenced galaxy growth far earlier than previously thought, when the universe was only 1.2 billion years old.
