Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY Researchers are using extraordinarily detailed computer simulations to reconstruct one of the most transformative periods in cosmic history: the era when the first stars and galaxies began to emerge. Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron.

The MEGATRON project could bridge JWST observations of the earliest galaxies with chemical clues preserved in ancient stars today. Science News from research organizations Powerful simulations reveal how the first stars changed the universe Powerful new simulations are recreating how the first stars lit up the Universe and forged the elements that eventually made planets and life possible.

Together, they represent the collaboration's first major collection of published results, with additional studies expected in the future.
