Lumina simulation brings the early universe to life

Simulations are becoming as important as telescopes in modern astronomy. Researchers at the Center for Astrophysics | Harvard & Smithsonian have developed Lumina, one of the largest and most detailed simulations ever created of the early universe.

The timing matters. The James Webb Space Telescope and the Nancy Roman Space Telescope are revealing the universe's earliest chapters in increasing detail, and observations alone can be hard to interpret. A model that recreates the early universe gives astronomers a reference point to test what they see against what theory predicts.

For anyone working in science communication, data visualization, or scientific computing, this is a reminder of how much the field depends on large-scale modeling and collaboration between institutions. The bridge between raw observation and understanding is increasingly built in code.

Where do you see simulation playing the biggest role in your field?
