Created to help astronomers interpret observations from the James Webb Space Telescope and the Nancy Roman Space Telescope, Lumina maps the cosmic web and illustrates how the earliest galaxies, stars, and structures emerged from the dark ages following the Big Bang. The simulation covers a scale of 1.5 billion light-years, offering unprecedented detail on primordial plasma, neutral hydrogen, and cosmic evolutio
