Powerful observatories such as NASA’s James Webb Space Telescope offer glimpses of galaxies that formed when the universe was still young, but new supercomputer simulations are helping fill the gaps in the mysterious early history of the cosmos.

Now, a team of international researchers has developed one of the most detailed models yet of the early universe, according to a recent study published in the scientific journal Monthly Notices of the Royal Astronomical Society.
