How NASA's Roman Space Telescope will rewind the universe

A new simulation shows how NASA's Nancy Grace Roman Space Telescope will turn back the cosmic clock, unveiling the evolving universe in ways that have never been possible before when it launches by May 2027. With its ability to rapidly image enormous swaths of space, Roman will help us understand how the universe transformed from a primordial sea of charged particles to the intricate network of vast cosmic structures we see today.
