## Resource

New observations from the James Webb Space Telescope and Subaru Telescope reveal that the environment was already shaping galaxy evolution just 1.2 billion years after the Big Bang. Scientists studying the ancient Loktak Protocluster discovered that galaxies in dense regions grew faster and developed larger outer structures than isolated systems. The findings suggest that cosmic neighborhoods influenced the size and evolution of galaxies far earlier than previously believed.
