How did the first stars transform the early universe? The MEGATRON project uses powerful cosmological simulations to trace the birth of primordial galaxies, the spread of starlight, and the creation of the first chemical elements. By connecting James Webb Space Telescope observations with clues preserved in ancient stars, the research offers a new way to investigate how the universe became enriched with the elements we see today.
