Lumina simulation brings the early universe to life on a record-breaking scale
Researchers at the Center for Astrophysics have developed 'Lumina,' a massive supercomputer simulation of the early universe's first 2 billion years. This tool helps astronomers interpret data from the James Webb and Nancy Roman space telescopes to refine theories on cosmic evolution.
Why it matters
Advanced simulations are critical for validating modern cosmological theories and interpreting data from next-generation space observatories.
